Target diPS in examIng

Within the framework of examING, an existing practical experiment at the Department of Communication Networks, which deals with the programming of sockets for communication on the Internet and practically deepens the understanding of Internet protocols by means of a few simple Java programs, is to be converted into a digital experiment while retaining the group work, which can be carried out completely online and thus opens up a Makerspace. The three existing experiment sections are to be retained:

  • By means of test questions, which are to be transferred into a Moodle online quiz, it will be checked whether the internship participants have the competences to carry out the experiment.
  • Afterwards, the required functions are to be added to the Java programs provided, for which the internship environment must be made accessible remotely. It should be possible for the internship group to work on the internship at any time, which is why a pause of the experiment and a later resumption should be supported. In addition, a communication channel between the group participants as well as between the group participants and the internship supervisor must be implemented.
  • Finally, the supplemented programs are to be started so that the communication can be monitored with the help of the freely available network monitoring tool Wireshark. Students must then analyze and interpret these measurements in a report to be submitted. The digital version of the lab experiment must then also provide a feedback channel for evaluating the report.

It should be ensured that all group participants:in participate equally in the experiment execution and thus achieve the goals of the internship.

Finally, feedback on the digitization of the experiment is to be obtained in a survey of the group participants in order to explore the possibility of digitizing other internship experiments at the department.

Target P:Mover

Intelligent transport solutions are being researched in Ilmenau's P:Mover project.

How can rural areas be better linked to the city? This question has been asked in Ilmenau since the territorial reform, which saw the municipality's area triple in size. In addition, there is a challenging topography and distinctive seasons due to its location in the Thuringian Forest. As a modern city with the seat of a technical university and "smart city" ambitions, Ilmenau thus becomes an ideal real laboratory: In the P:Mover project, entrepreneurs and scientists are jointly researching intelligent transport solutions that are of supraregional importance for the structural change of local public transport (ÖPNV).

Automated vehicles are combined with the latest generation of mobile communications.

A high degree of vehicle automation combined with the latest generation of mobile communications offers scope for innovation. The powerful real-time data connection of the 5G network is not only the basis for autonomous local public transport in the future. It also opens up new possibilities for passenger information systems and municipal tasks such as road condition monitoring. The P:Mover project is working on the challenges of the future.

Target EXIST

With Cotrack Link, we want to develop a wearable that connects groups in a simple way. Joint activities of families, children, youth and sports groups require a high degree of coordination and organization. Thus, it easily happens that group participants unintentionally stray too far from the group or that simple arrangements cost a lot of time. This is a particular burden for supervisors such as educators, caregivers, mothers or fathers. We developed the idea of a wearable that wirelessly connects group participants and enables direct communication with the group. Our technology has four main performance characteristics:

  • A self-sufficient, encrypted network: group participants form a decentralized wireless network independent of existing cellular networks and usage fees. Using powerful 868 MHz radio technology, they remain connected even at long distances (up to 8 km).
  • Distance warning: If a single subscriber threatens to move too far away from the group, a warning is signaled to him and the group management. Each Cotrack link also presents a representation of the group's propagation radius (virtual group radius).
  • Group Ping: Each participant can be identified by a color. If a participant pushes a button, all other group participants will receive a light signal in the color of the sender.
  • Ultraportable: The small and lightweight terminal can be attached to wrist, backpack or clothing. The battery life of several weeks allows it to be worn continuously.

Duration: from 01.10.2019 to 30.09.2020

Target Objective TOK-MASK Innovation Voucher

This project was designed as an R&D cooperation project for the development of a networked adaptive sensor system for monitoring and analyzing physical processes and systems arranged over a wide area for application areas such as building monitoring, Industry 4.0 or security technology. The AI-supported analysis and documentation of physical processes will be implemented for a wide variety of application areas for object data acquisition, such as holistic monitoring, hazard detection and the realization of comprehensive security structures. This is to be achieved by the core module for the pre-detection and defense of hidden and unforeseeable dangers, for the averting of undesired events and their consequential effects, from physical processes and sequences. Further modules that can be added flexibly allow the object data monitoring to be adapted and individually designed.

Target Power- & Radio Train

A total of 7 departments of the TU Ilmenau are involved in the PORT research group, whereby the research group itself belongs to the "Thuringian Innovation Center Mobility" (ThIMo, According to the name of this project, which is composed of the words Power- and Radio-Train, both drive systems and information technologies for new vehicle concepts are at the center of the research activity. The field of communication networks deals with two challenges in particular. On the one hand, internal vehicle communication and its possible redesign are examined in more detail. In the future, the trend towards an increasing share of information, communication and sensor technology will necessitate a new networking concept in the vehicle, as existing systems have only been developed to a very limited extent in the past and will reach their performance limits in the future. Ethernet is a much-discussed option that can offer the necessary performance for gateway networking. However, Ethernet can only guarantee technically secure communication within strict limits, as is necessary in the safety-sensitive automotive environment. Therefore, extensions such as Ethernet AVB or middleware-based approaches will be investigated in more detail in order to clarify the question whether and how a secure vehicle network can be realized with these means. On the other hand, the topic of "vehicle-to-vehicle communication" (in English "car-to-car" or often "C2C" for short) will be examined more closely as a research object. The vision of intelligent assistance systems and ultimately fully autonomous vehicles can only be realized if the vehicles can recognize their surroundings and exchange information with them. Since such a network is extremely dynamic due to the varied road conditions and traffic situations, it must be investigated here how this information exchange can be designed efficiently and reliably.

Target Smart Home Service

The objective is to realize a system that can be used as a universal basic infrastructure to realize an intelligent house. However, not only the system structure but also corresponding applications to realize this goal shall be designed, developed and integrated.

The SHS project has been initiated by the industry cluster ELMUG eG (Elektronische Mess- und Gerätetechnik). This has been subdivided into various specialist groups. The SHS project is assigned to the group "Building Services Engineering". In order to better manage this extensive project, the SHS project has been divided into three sub-projects:

  • SHS: Facility
  • SHS: Services
  • SHS: Home

As already indicated, the SHS project aims to design and realize the intelligent home of the future. Both the landlord and the tenant are to benefit from this new system in order to ensure acceptance on both sides and to increase marketing opportunities. The SHS: Facility subproject focuses primarily on the tasks to be implemented in order to make the system attractive from the landlord's point of view, including, for example, the central recording of heating costs. SHS: Services attempts to implement services for the tenant based on the information obtained from the installed infrastructure and from sensors such as motion detectors, smoke detectors and temperature sensors in the individual apartments. This could be, for example, a configurable heating control, which ensures a different room temperature depending on the presence or absence of the tenant. It would also be possible to monitor electricity consumption or to selectively switch off the power supply to electrical appliances in stand-by mode during the night in order to reduce electricity consumption and the associated costs.

Target Knowledge-based technologies and needs-based services for seniors through individualized care concepts.

In this project, algorithms were developed for the sustainable optimization (in terms of mediation and timing) of existing, as well as integration of newly created age appropriate services, taking into account the specific requirements of service providers and the specific needs of service users. Methods for monitoring spatial (position, direction of movement, speed of movement) and physical (pulse, ECG, blood sugar) parameters were developed. Prototype hardware was also built to integrate physical and position sensors and to ensure location-independent and transmission channel-transparent communication. Routing, addressing, and coding methods were created to ensure the customer's (senior and service provider) usual and or preferred mode of communication (telephone, Internet, face-to-face). Service dependent requirements were considered with the possibility of implementation between communication channels.

The following subtasks were implemented:

  • Interest- and ability-oriented mediation of service offers (care, social contacts, hobby, wellness, ...) and assistance in the perception of these offers,
  • Route guidance for the perception of services, control of compliance with specified areas in the case of corresponding mental restrictions (e.g. Alzheimer's, dementia) as well as monitoring of compliance with medically specified vital parameter limits,
  • Wide access to services by lifting the perception limits set by preferred communication channels (offers only by e-mail, ...) among seniors. Maintenance of data transmission under changing transmission conditions.

Proof of functionality was provided by building an infrastructure and implementing the assistance system in three scenarios.

Additional information about farsightedness

In the WEITBLICK project, an assistance system with comprehensive, complementary communication structures and a dynamic, self-adapting knowledge base is being developed that provides comprehensive support to users in requesting services according to their needs and in coordinating the timing of service provision, thus integrating them into the community. A structured and organized but adaptive information flow is the central element. The following system functionality is planned:

  • Recommendation and mediation of service offers (care, household errands, cultural offers, contacts between users, offers from users themselves).
  • Device-independent, flexible communication infrastructure
  • Provision of an infrastructure to improve existing and create new service offers

This will enable an improvement in the quality of life and a longer, self-determined life at home. The implementation of the project goals is prepared as follows:

  • Establishment of a knowledge base for the structured mapping of users and offers
  • Application of the knowledge base for service recommendation and optimization, and possibly detection of missing services
  • Creation of concepts for monitoring seniors

The developed and implemented assistance modules will be evaluated by implementing three scenarios in cooperation with different institutions of the elderly care association of the AWO in Ilmenau.

Mobile info point

For the mobile info point of the SEI company, the information system is to be transferred to a platform that enables mobile use as a pocket device and integrates the barrier-free interface. This platform has to be realized by a commonly available device, which is therefore available at an affordable price. A first proposal is the use of a personal digital assistant (PDA).

The information inventory is significantly enhanced by geographic references and device technology with a GPS for location determination. This means that the determined location information must be sent to the control center, where corresponding information must be sent back to the mobile info point. This communication should be based on wireless communication techniques, as this is the only way to enable the mobility of the device. For cost reasons, it is quite appropriate to integrate several network interfaces into the mobile info point so that the optimal technology can be selected in each case. In addition, the barrier-free terminals should be equipped with wireless network access technology so that they can serve as switching devices between the control center and the mobile info points.

Personal attendant

The personal attendant is a mobile terminal that is shaped and sized in such a way that the tourist, can easily integrate such a device into his environment without any additional aids. There are already a number of such devices available. These include PDAs (personal digital assistants) or handhelds, palmtops, smaller notebooks, webpads, mobile phones, etc. The personal companion is intended to serve the user as an access point to information of the tourist environment. To realize this functionality, the following objectives should be achieved. Based on the results obtained under the previous working point, general en devices shall be used as personal companions. Therefore, on the one hand a device independence is in the foreground, which has to be achieved by the fact that the developed mobile infopoint is modular and therefore only the device specific modules have to be changed. On the other hand, in the case of a personal companion, a much more detailed user profile can be created, which allows optimal adaptation of the information displayed and the information transmitted. This is especially important for multimedia information to be sent to the user. Only this allows for an easily understandable presentation of the transmitted information that can be used even by inexperienced users. From different possibilities for the localization of the tourist, e.g. with the help of GPS, tags, field strength measurements, a suitable and cost-effective variant is to be selected for the area to be technically developed. The different areas to be considered have to be categorized, because the technical realization of the localization has to be done differently in higher frequented tourist areas (e.g. sight) compared to lower frequented areas (e.g. hiking trail). Furthermore, the end devices are to be examined with regard to their usability. This includes the technical feasibility of the localization, the connection to the TAS network as well as a user-friendly operability of the end devices. For the connection to the network, different transmission methods will be investigated according to the geographical conditions and technical feasibility. Possible access variants here are GPRS (General Packet Radio Services), WLAN (Wireless Local Area Network), GSM (Global System for Mobile Communication) or UMTS (Universal Mobile Telecommunication System). The first context-sensitive approaches are to be implemented for the personal companion. For example, it is conceivable that tour planning could be based on a person's degree of walking disability. In this case, the routing for a wheelchair user may not include stairs, high curbs, narrow gates or doors, while this is usually not a problem for a person without a walking disability. Likewise, solutions for the visually impaired (e.g., audio playback of information) must be implemented and verified. Finally, the system is also of interest to tradesmen. Through the addressed localization, it will be possible to draw the tourist's attention specifically to nearby offers (e.g. restaurants, souvenirs, etc.).

Personal assistant

The personal assistant has the same capabilities as the personal companion described above, but is extended by some functionalities. With the help of sensors and appropriate technical modifications, it can record the context of a tourist more extensively than described above. After analyzing this data, the tourist is provided with information specific to his or her current situation. This information can depend on the time of day, the weather, or the like. This makes it possible, for example, to guide tourists only to sights or museums that are open at the current time. Another example would be the weather. In case of rain, unpaved roads are simply avoided during route planning. It has to be investigated which contextual information is of interest and useful. Context awareness strategies need to be developed and implemented. The usability of the different end devices has to be verified. Since the interaction possibilities by the user are in the foreground here, with the mobile end device taking a back seat rather in the sense of ubiquitous computer use, new user interfaces are to be defined and context-sensitive services and adaptations are to be designed. For this purpose, the user profile defined in the previous work item must be refined once again and enriched with the aforementioned context data from the environment. This has just as effects on communication.

Conception of the networking of the individual components

In order for the information to be communicated between the control center, the accessible terminals and the mobile devices that the tourists will use (mobile info point, personal attendant, personal assistant), a concept for networking must first be created.


The main scientific/technical goal of the project is the sensible combination of communication and automation technology for the control of integral building services systems. A modular "togetherness" of both technologies shall be realized to cost-efficient solutions, by the multiple usability of an embedded microcomputer (LISTIG-Basisgerat), whose modifications are achieved by plug-in modules, smart cards and/or downloads.

Target study Mobilcom

The object of the study was to examine mobile applications and mobile terminals. In particular, offerings based on GSM - GPRS/HSCSD, W-LAN and UMTS (IMT-2000 as an international platform for broadband mobile networks and their applications, e.g., NTT DOCOMO) and mobile applications that develop independently of specific networks and terminal devices had to be taken into account. Of course, the trends in network development themselves were also of interest, since they played a major role in determining the framework of future applications. Specific trends of the next generation (4G or beyond 3G) were consequently to be taken into account. In particular, the results of current projects on telelearning, location-dependent services (e.g., tourist assistance systems) and context-dependent services were incorporated into this study.

The following subtasks were addressed:

  • Communication services for mobile subscribers
  • Requirements for mobile communication networks and terminals (especially mobile radio)
  • Trends in the development of mobile communication networks
  • Trends in the development of mobile terminals

In addition, it can also be used for demonstrations in the context of events of the TU and for the recruitment of students. On the other hand, from a scientific point of view, the conception and realization of mechanisms for the integration of mobile devices into multimedia applications should be mentioned as a goal.

DescriptionFor the research focus "Mobile Communication", several institutes at the TU Ilmenau cooperate across faculties in order to be able to competently deal with all aspects of the broad research field to which this focus is dedicated. An essential aspect, on which the success of this research focus also depends, is the acceptance of the research results in industry, which in turn is geared towards increased demand on the customer side. Thus, it must be possible to realize and demonstrate applications that indicate customer interest.Therefore, a laboratory for the demonstration of multimedia applications in the mobile environment must first be established in the environment of the research focus. On the one hand, this laboratory should have the latest technology from the multimedia field, but on the other hand it should also use products from the mobile communications market. A major problem of mobile communication networks is the mobility of subscribers and the handover of information streams that this requires. For its reproduction and the investigation of the emerging quality of the representation of multimedia information streams, the division of the laboratory into at least two spatially separated parts is inevitable. Multimedia has many facets and does not simply consist of a mixture of text, images andaudio/video sequences. On the one hand, the synchronization of the individual media streams must be taken into account. On the other hand, the enormous information content of such streams requires an efficient and yet easy-to-process compression with little loss. If both are already very problematic to handle in the fixed network area, the complexity for mobile end users increases even more by orders of magnitude. These usually have a limited transmission channel that allows only low transmission rates and is also extremely error-prone, so that disconnections and missing connectivity must be expected even more frequently.Furthermore, a mobile terminal does not have the same resources available as its counterparts in the fixed network. Limited displays with low color depth, poor audio reproduction, weak computing power and limited memory capacity must therefore be taken into account in multimedia applications. This has particular implications for group communications applications, where some of the fixed network receivers have sufficient resources to reproduce the multimedia stream in the best possible way, whereas mobile subscribers cannot receive or process such a stream at all. But also in the mobile area, very heterogeneous participants have to be taken into account: On the one hand, a modern seminar room with the help of a wireless local area network offers much better transmission speed and quality than a mobile participant who is driving his vehicle at a speed of 200 km/h can experience. Thus, the higher the mobility requirements of the end participants, the more difficult it becomes to provide an appealing communication service quality for these participants. Finally, interactive multimedia applications must also be controllable, which is possible without much effort in the fixed network using conventional input devices such as keyboard, mouse, trackball or touchpad. In the case of mobile devices, however, which are characterized primarily by their small size, such input mechanisms are often not practical. Innovative inputs must then be made possible there, based on voice recognition or touch-sensitive displays, for example. User interfaces must therefore be adapted for mobile end devices.

Target LLK

The aim of the project was to provide tools for the development and use of multimedia and interactive learning documents and their integration into digital learning platforms. In contrast to e.g. authoring systems, these should enable the integration of existing documents of different types. However, the documents should not only be integrated, but also provided with special attributes and interfaces to the learning platforms. Learning is understood as an interaction between teacher and student, thus promoting the active role of the student. Thus, innovative didactic concepts such as cognitivism and constructivism were supported, which require as a technical prerequisite the extension and motivation of student interactions.

Continuing education and multimedia learning technologies

The current global development in almost all fields, which is characterized by a rapid increase in knowledge in all areas, places completely new demands on education. The constant updating of knowledge but also the professional reorientation require lifelong learning of ever broader layers of the population. In particularly innovative disciplines, deficits can already be clearly seen today. This results in a growing need for continuing education. In continuing education, which is mostly part-time, there are a number of special requirements with regard to time efficiency and individual support. One approach to meeting these demands is the use of new, multimedia learning technologies. At present, exaggerated hopes have been placed in the new technologies. Now that valuable practical experience is available, it is becoming clear which problems need to be addressed. An important aspect is the use of the possibilities of new technologies for the change of the learning process and not the preparation of the learning contents with in the nearly same teaching and learning behavior.

Necessity of the project

Previous developments in the field of new learning technologies can be characterized mainly in three directions:

  • Development of multimedia teaching documents, often referred to as Computer Based Training (CBT). They are usually developed and implemented on the basis of special systems supporting the authors. The main goal is to use the media and special concepts such as hypertext to provide new teaching materials. The interactivity is often limited to the possibility of elegant navigation. However, it is difficult to promote an active role of the learner through this, i.e. to support new didactic concepts such as cognitivism and constructivism.
  • Development of interactive, net-enabled learning modules (Web Based Training WBT). They are typically created from scratch using net-oriented programming languages such as HTML and JAVA. This programming is very complex and requires appropriate computer science skills.
  • Development of so-called learning platforms, also referred to as learning environments, virtual learning environments, etc. Fundamental is in any case the use of telecommunication possibilities of modern data networks like the internet. The learning platforms should above all be independent of the hardware platform and provide a user and document (or generally information) management. The design of the documents is not directly considered, it should be possible to use all occurring formats and types. It is to be recognized that a comfortable support of the production of electronic, multimedia learning documents, which are platform-independent, is missing. Rather, it is necessary to create tools or libraries of classes that facilitate the programming of net-based modules. They are the necessary prerequisite to use multimedia possibilities at all in the presentation of certain facts and to integrate simulations.

Solution approach

It is difficult to achieve the presented goals with integrated tools. An alternative is the use of programming languages and thus programming of the documents. However, this method is considerably more costly compared to the use of integrated tools. A comparison of the requirements with the paradigms of object-oriented programming shows however that the represented tasks can be solved by a class library. By integration of class library and programming surface (e.g. Java cafe or visual Java) can be partially achieved similar working environments as with authoring systems. The inheritance of classes makes however a constant expandability and free use and organization possible. The concept of the Bottom up Design inherent in the object-oriented programming promotes the use of existing elements and functions and thus existing interfaces and also organization guidelines, which again a uniform Look and Feel benefits. In order to realize the greatest possible platform independence, Java is to be used as the programming language within the project. In the AMULET project, good experience with this approach has already been gained in another field of education.

Procedure, expected results of the project

Within the project, an existing teaching module of the Telecommunications Manager course, which is currently offered as a purely classroom-based course, is to be converted into a learning program. The learning program is to be used to acquire a part of the material in self-study and to be able to supplement it with a seminar. A script and a slideshow exist, which were created with different tools. Within the project it is to be examined first, which supplementing characteristics must be added to the existing materials for the organization as learning software. This will be followed by an investigation of which of the features can be provided with existing tools that have already been adopted unchanged or slightly modified. The missing characteristics are then abstracted as far as possible and transferred into an inheritance hierarchy, which becomes finally basis of a class library. With the help of this library then the learning program is to be provided. The work is to be accomplished as far as possible independently of the used programming language, practical work is to be accomplished in Java.

The result will be a class library as a basis for the transfer of existing documents into WBT. This can be continued and supplemented as desired. The object-oriented paradigm ensures that partial results are also used when deriving new classes. The teaching module, which is being developed as a practical example, will make the telecommunications manager course, which has been very successful up to now, even more attractive. In an evaluation phase, students are encouraged to develop self-study materials and also offer them to fellow students for use. In particular, the effort-benefit ratio and acceptance will be supported.

Involvement of students

Student research topics will be assigned for research on existing tools and conceptual research on specific issues. Especially for programming, student assistants are used, who have and want to consolidate practical programming skills. This practice has already been successfully applied in past work. For the programming of user interfaces especially students of the study course media technology are recruited. The participating students will also be involved in the conceptual discussion. In particular, they can provide important input from the learners' point of view. The continuing education course students have been and will be involved in the evaluation of the learning software by providing important feedback on the extent to which the set goals have been achieved. Furthermore, they are able to provide important hints from the perspective of potential future users.

Target learning environments

In this project, selected contents of university teaching at the TU Ilmenau were prepared for further education and distance learning using the advantages of modern information and communication technologies. Part of these results could also be used for direct engineering education.
