Thema

Optimal Frequency Reuse Rules for High Reliability Low Latency Future Cellular Communication

Typ:
Masterarbeit
Betreuer:
M. Sc. Gebrehiwet Gebrekrstos Lema
Status:
ausgeschrieben
Beschreibung:

In recent years, Long Term Evolution (LTE) cellular networks are rapidly growing in 4G cellular systems. LTE has come up with increased user Quality of Service (QoS) and even better QoS is expected in 5G. However, the bandwidth and frequency spectrum to support these services is critically limited. To address this, service providers need new tools to help them efficiently and effectively optimize their networks. Though different techniques have been proposed against this, it is evident that they either increase in system complexity or results in significant degradation of the quality of service [1].
Hence, in the next generation network designs, an optimal frequency reuse rule is needed that not only maximizes the spectral efficiency but also guarantees the High Reliability Low Latency (HRLL) communications. It would thus be worth revisiting more advanced efficient and effective frequency reuse technique that results in HRLL at minimum possible system cost [2].

Tasks:
1. Literature study on frequency reuse in 4G/5G cellular communications
2. Investigate the impact of frequency reuse in supporting HRLL communications
3. Propose an optimal frequency reuse technique that meets the HRLL requirements
4. Implement and show its novelty with different types of user profiles and/or with different radio conditions

Requirements:
1. The passion of scientific research
2. Knowledge of cellular communication systems
3. Very good programming skills in MATLAB/C#/C++ (any one of them)

Radio Resource Allocation Algorithms in Overlay Vehicle-to-Vehicle (V2V) Communications for 5G Wireless Networks

Typ:
Masterarbeit
Betreuer:
M.Sc. Dariush M. Soleymani
Status:
ausgeschrieben
Beschreibung:
Vehicle-to-vehicle (V2V) based on device-to-device (D2D) communications were introduced in Release 12 and Release 13 of 3GPP standard. Generally, the connected vehicles are likely utilized for mission critical applications, which needs extremely high-reliable and low-latency communications. Due to extremely dynamic propagation environment of V2V communications, several challenges have emerged. One of key challenges is efficient usage of radio resources. To this end, two approaches are available, overlay and underlay resource allocation. Here, we mainly focus on overlay radio resource allocation and aim to find avenues to fulfill low-latency and high-reliability required by V2V communications. In addition, the proposed algorithms should be robust for both high-speed and low-speed vehicles.
Tasks:
• Literature review on radio resource allocation algorithms in V2V communications.
• Study on potential applications used in V2V communications
• Propose a novel algorithm to allocate radio resources in an efficient way
• Preparation of scenarios and models to evaluate the proposed algorithms
Requirements:
• Very Good knowledge of wireless communications, i.e. LTE, D2D and V2V
• Very good knowledge of C++ programing language
• Knowledge of NS3 simulator / MATLAB (OOP)

Hauptseminar
Betreuer:
M.Sc. Oleksandr Andryeyev
Status:
ausgeschrieben
Beschreibung:
According to the literature, users of mobile stations (MSs) usually are moving in a predictable pattern. Moreover, together they are organizing clusters.
Usually it is assumed that each user is doing random walk while we are interested also in the movement of a cluster itself. Thus, the mobility model with the following features should be implemented:
* each user is moving inside the cluster
* the cluster is moving towards some target waypoint
* support for different mobility patterns - uniform random walk, Gaussian random walk etc.
Main focus of this work:
* Literature study on available models
* Mobility model implementation
* Verification of the developed model
Requirements:
* Analytical mind, ability to work independently
* Python programming skills

Novel Dynamic Path Planning Algorithm for localization of wireless nodes in multi-UAV scenario using implicit signaling in DTN

Typ:
Masterarbeit
Betreuer:
M. Sc. Alina Rubina
M.Sc. Mehdi Harounabadi
Status:
ausgeschrieben
Beschreibung:
In unknown environments, dynamic trajectory planning for a UAV represents an effective solution for localizing wireless nodes. The UAV must localize wireless nodes accurately and efficiently without wasting resources.
However, employing a single UAV for localization in vast areas causes long latency and may not be feasible. To overcome these problems, multiple UAVs can be applied in the network.
In this case, cooperation between UAVs is required to avoid redundant visits of already localized nodes. Also, covering the same area by different UAVs will waste time and time is the most crucial parameter in disaster scenarios.
As UAVs may not be always connected to exchange information about their planned trajectory and localized nodes, one possible solution will be employing a signaling of control information among UAVs.
There are two types of signaling. In the first case an explicit signaling is used, where a UAV exchanges the control information whenever it encounters another UAV. However, in the vast networks this cannot be applicable as UAVs have short communication range.
The other feasible solution is implicit signaling through wireless nodes. This can also be called delay tolerant signaling. To implement this, a list of localized nodes is stored in the network among localized nodes.
Wireless nodes act as relay nodes to exchange signaling information among UAVs (indirect signaling of UAVs).
By indirect signaling of UAVs through nodes, the redundancy in time, covered area and number of localized nodes can be decreased significantly. It can improve the latency of localization and decrease the traveled distance of UAVs.
Tasks of the student:
1- Literature review about existing work in static and dynamic UAV trajectory planning for localization and delay tolerant networks routing
2- Developing a cooperative multi-UAV dynamic trajectory planning approach for localization of wireless nodes employing indirect signaling among UAVs
a. Modeling the problem
b. Proposing a solution for the modeled problem
3-Implementation and evaluation of the proposed algorithm comparing two scenarios: no signaling and indirect signaling

Implementation and Evaluation of Different Path Planning Algorithms for UAV in Wireless Networks

Typ:
Masterarbeit
Betreuer:
M. Sc. Alina Rubina
Status:
ausgeschrieben
Beschreibung:
Quite recently, considerable attention has been paid to the problem of anchor placement, i.e. a design of a trajectory for a mobile anchor (UAV in our case). Previous studies on this issue have shown that a well-planned mobile anchor trajectory increases the speed and accuracy of the localization process [1].
In this paper, one very challenging scenario is considered where an unmanned aerial vehicle (UAV) is flying over an urban area, which suffers from a disaster. The purpose of a UAV is to localize ’survived’ devices, enabled with Wi-Fi module. The obtained information will help to accelerate the rescue process of people who are stuck inside a building.
This work will be mainly divided into two parts:
1) Simulation part
Implementation of chosen three trajectories (namely, Sierpiński curve, Lebesgue curve and Peano curve) in Python.
Simulation of those and comparison with the existing trajectories.
Consideration of two scenarios, with and without a building.
Based on the simulation results, choosing one or two for the experimental evaluation.
2) Experimental part
Evaluation of the chosen trajectory in a real-world experiment considering two scenarios.

Applying the solution of MTSP for path planning of multiple message ferries

Typ:
Advanced Research Project (MSCSP)
Betreuer:
M.Sc. Mehdi Harounabadi
Status:
ausgeschrieben
Beschreibung:
Message ferrying is a solution to exchange delay tolerant messages among disconnected wireless nodes that are located out of the transmission range of each other. A ferry node (e.g. UAV), travels among disconnected nodes and deliver their messages. The mobility of a ferry node can be controlled and its travel path can be given in advance. The solution for Multiple Traveling Salesman Problem (MTSP) is a possibility to plan the path of message ferries when several ferries are employed in a network.
The goal of this project is to study MTSP solutions and apply one of them in the multi ferry path planning problem.

Performance evaluation of different multi-ferry path planning approaches

Typ:
Masterarbeit
Betreuer:
M.Sc. Mehdi Harounabadi
Status:
ausgeschrieben
Beschreibung:
Message ferrying is a solution to exchange delay tolerant messages among distant wireless nodes that are located out of the transmission range of each other. The ferry node (UAV), flies to visit ground nodes and in each contact exchange information with them. Ferry is a wireless node with controllable mobility. It picks up messages from a ground node, flies to the destination and offloads messages. Decision about which ground node to visit (ferry path planning) impacts the performance of message forwarding in network. Having a single ferry in networks that has been established in large areas cannot support communication needs of different traffic types in the network. Multi-ferry approach employs several ferries in the network to meet the performance requirements of the network. Several approaches has been proposed in literature for multi ferry path planning. The objective of this project is:
1. Literature study on existing multi ferry path planning approaches
2. Implementation of some of the selected multi ferry approaches on the existing simulator (python based simulator)
3. Investigation on results to make conclusion

E-Assessment auf Basis interaktiver Simulationswerkzeuge

Typ:
Masterarbeit
Betreuer:

Christian Saul
Status:
ausgeschrieben
Beschreibung:
Existierende E-Assessment-Systeme, sowohl Alleinstehende (z.B. Questionmark Perception, Respondus) als auch in Lernplattformen (z.B. moodle, ILIAS, Backboard) integrierte Werkzeuge setzen nur einfache Fragetypen (z.B. Multiple-Choice) für die Überprüfung des gelernten Wissens ein. Dies ermöglicht meist nur das Abprüfen von Faktenwissen. Eine selbstständige Bearbeitung komplexer Verständnis-, Anwendungs- und Analyseaufgaben kann damit nicht überprüft werden. Bezogen auf die Bloom’sche Taxonomie bedeutet dies, dass die unteren Stufen durch bestehende Assessment-Systeme und -Werkzeuge abgedeckt werden, wohingegen die oberen 3 (Analyse, Synthese, Evaluation), auch als Kompetenzen höherer Ordnung bezeichnet, ein Problem darstellen.

Ziel dieser Arbeit ist die konzeptuelle Integration von interaktiven und simulativen Werkzeugen in die Prozesse eines E-Assessment-Systems und deren prototypische Implementierung am Beispiel des am FG Integrierte Kommunikationssysteme entwickelten Online-Laboratoriums RemoteLab sowie des am Fraunhofer IDMT entwickelten E-Assessment-Systems askme!.

Beschreibung:
Multimediale Lehr- und Lerninhalte (oder kurz „Lernobjekte“) sind in den unterschiedlichsten Technologien bezüglich Erzeugung, Speichermedium und Distributionsmöglichkeiten in den letzten Jahren entwickelt worden. Es wurden unterschiedliche Autorenwerkzeuge eingesetzt, die die weitere Verwendbarkeit der so erzeugten Lernobjekte wesentlich beeinflussen. Sie werden entweder auf Datenträgern und Servern der Autoren oder komfortabler in Contentmanagement- (CMS) oder Lernmanagement- Systemen (LMS) verwaltet. Um derartige Materialien zu nutzen gibt es gegenwärtig nur die Möglichkeit, in Kontakt mit den Autoren zu treten und individuelle Kooperationen einzugehen. Sollen die Materialien dann zusätzlich noch in einen neuen, eigenen Kontext gestellt werden, so ist der hierfür notwendige Arbeitsaufwand meist höher als ein Neuentwurf.

Zeil des Hauptseminars ist es, exemplarisch wiederverwendbare Lernobjekte zu realisieren, die auf unterschiedlichen Plattformen laufen können.

Robust Resource Allocation Algorithm for Overlay D2D Communication in Intersection Area

Typ:
Masterarbeit
Betreuer:
M.Sc. Dariush M. Soleymani
Bearbeiter:
Avinash Tarale
Status:
in Bearbeitung
Beschreibung:
The continuous increasing of connected devices in near future has inspired the evolution of cellular communication networks from 4G to 5G. For fulfillment of the rising needs of users and efficient utilization of the available scarce resources, device-to-device (D2D) communication is being looked upon as an important emerging technology for present and future cellular networks.
According to 3GPP, D2D communication is classified into two modes or categories.
• In-band underlay mode (Mode I): D2D and the cellular users share resources
• In-band overlay mode (Mode II): Separate radio resources are allocated for the D2D communications.
A wide range of researches has been done in Mode I as compared to Mode 2. In Mode I,the main challenge is to find an appropriate algorithm to mitigate the arising interference due to sharing the radio resources. However, in Mode II, the proposed guidelines by 3GPP fail to provide an appropriate strategy to fulfill the applications with high-reliability and low-latency requirements. In addition, when the D2D users are in the intersection area between two cells, finding an optimal algorithm becomes even more complicated. Here, in this study, we aim to find methodology to allocate resources more efficiently to D2D users located in the intersection area.
Tasks:
• Literature review in radio resource allocation in D2D communication.
• Propose a methodology for distributed, de-centralized resource allocation
for Mode II D2D communications in intersection area.
• Evaluation of the proposed algorithms.
• Preparation of scenarios and models to evaluate the proposed algorithms

Requirements:
• Very Good knowledge of wireless communications, i.e. LTE, D2D
• Very good knowledge of C++ programing language
• Knowledge of NS3 simulator

Implementation of localization software for UAV in real-time

Betreuer:
M. Sc. Alina Rubina
Status:
in Bearbeitung
Beschreibung:
In this project we are considering mobile anchor based localization. We are using an UAV as a mobile anchor and mobile phones represent wireless sensors. UAV explors the area and measures received signal strength of mobile phones which need to be localized. Localization process includes mapping those received signal strengths to distances. Also, knowing the distances we can estimate the position of the node.
The main goal of this project is to develop a localization software for UAV. This software needs to process data in real-time.
