Status:: finished
Abstract:: Since mobility models are the basis for the planning of new Radio Networks, the aim of this work is to test different mobility models, which are used for mobile communication. These models are tested for their advantages and disadvantages in selected szenarios. Some of these models are implemented and simulated in the CRRM- Simulator and the results are analyzed. Additionally a self developed mobility model is tested for its applicability. The models are implemented with the programming language Java.

Abstract:: This paper deals with the application of agents in the field of software programming. It briefly explains this concept and shows advantages of the Java programming language in this application area. The second part will present some agent systems. After that there is a detailed description of the “Java Agent Development Framework“ JADE, which is particularly suitable for our practical needs. It also shows a mobile agent as an application example.

Placement of software services on servern in communication networks

Kind of work:: Diploma Thesis
Supervisor:: Dr.-Ing. Florian Liers
Students:: Ronny Lehmann
Status:: finished
Abstract:: This diploma thesis deals with the placement of services on servers in a network. The main question, on which node one or more servers should be installed, was investigated. This problem is known in graph theory as the "k-median problem". In the course of this thesis different algorithms, known from literature, were classified. Afterwards a selection of those algorithms was tested on real as well as on generated networks. Four algorithms were chosen for testing: Random, BruteForce, HotSpot-Greedy and HotSpot-Cluster. Thus it was possible to compare their result quality, implementation complexity and run-time complexity. It turned out that the results were depending on network topology and parameters. Therefore no universal algorithm exists to solve the problem even though the random algorithm provided good results nearly everytime.

Multiagentsystems and Onotologies

Kind of work:: Advanced Seminar

Status:: finished
Abstract:: This paper deals with the combination of Multi-Agent-Systems and Ontologies. Our intention was to present several applications based on examples issued in literature.
Eventually potential perspectives of this synergy will be highlighted and evaluated in the form of devised scenarios.
As an approach we decided to firstly provide an insight into basics of Agents and Multi-Agent-Systems as well as Ontologies. Chapter 2 deals with these issues in order to communicate essential knowledge to build up on in Chapter 3. Here we point out the conjunction of both concepts on the basis of the mentioned examples in literature in a practice-oriented way.
Finally this issue is enhanced in Chapter 4, where we will discuss some specific scenarios which could be, according to our view, the future of technological development. We will end with a summarizing review based on the exposed applications.

Design of an QoS-aware Multicast Protocol for MPLS-based Radio Access Networks

Kind of work:: Diploma Thesis
Supervisor:: Dipl.-Ing. René Böringer
Students:: Steffen Schmidt
Status:: finished
Abstract:: This document describes two approaches for the integration of a Quality of Service-aware multicast into MPLS-based Radio Access Networks (RAN). The first protocol, O-MRP (Multicast Tree Optimization-enabled QoS-aware Multicast Routing Protocol), simply relies on an IP network structure. O-MRP provides fast joining and leaving capabilities for mobile users to multicast groups. Additionally, the protocol allows for multicast route optimization, aiming on different optimization goals. O-MRP uses a unicast routing protocol to construct multicast routing tables. I-MRP (Integrated Multicast Routing Protocol), on the other hand, directly integrates into MPLS and RSVP-TE. For this purpose I-MRP extends RSVP-TE to distribute multicast routing information over the MPLS network and construct multicast Label Switched Paths (LSP). I-MRP, however, does not support multicast route optimization. Both approaches require only changes to routers within the RAN. The protocols are transparent to Mobile Nodes (MN) and network elements outside the RAN.

Self-organizing Monitoring for MPLS-based Networks

Kind of work:: Diploma Thesis
Supervisor:: Dipl.-Ing. René Böringer
Students:: Stefan Leistritz
Status:: finished
Abstract:: MultiProtocol Label Switching (MPLS)- based networks obtaining more and more acceptability and distribution in provider- and backbone networks. Nevertheless, concepts for monitoring MPLS-based networks efficiently are still missing. In this diploma thesis a concept for self-organizing monitoring for MPLS-based networks is developed. At first some possibilities of designing monitoring more efficiently by using MPLS-specific information are shown. Therefore it is shown how to maximize the advantage of a single monitor by using information out of existing signaling messages (RSVP-TE). Based on this knowledge a novel concept of monitoring the whole network
with only a couple of monitors is proposed. Afterwards different positioning algorithms are studied. This helps for reducing the number of necessary monitors to a minimum. The concept of positioning of monitors at runtime should requires for new network management technologies.
By means of these approaches the monitoring system can adapt itself to different situations in the network. The behavior
and opportunities of these positioning algorithms are simulated in Matlab and by means of various MPLS-based networks reference networks. At last the extensibility of this concept and some possibilities for transferring the gained results to other technologies are shown. This work shows that only 10% of the networks nodes have to be monitors. It is sufficient that each of these monitors observe only 10 randomly chosen LSPs to monitor the whole network completly.
