Research Focus of Our Group

In recent years, Peer-to-Peer (P2P) file sharing systems for the Internet have gained rapidly increasing popularity. Meanwhile, more than 70% of the traffic in the backbone of the Internet is generated by such P2P systems. The major advantages of P2P mechanisms compared to traditional client/server mechanisms lie in the increased scalability for supporting millions of users as well as achieving more dependability through decentralization. However, the P2P concept is not only restricted on file-sharing, but may also be deployed for decentralized coordination and communication in a variety of other distributed applications.
The focus of previous research and development for mobile software systems is almost solely based on the client/server approach, without exploring or exploiting the numerous possibilities and challenges provided by P2P mechanisms. P2P mechanisms can be deployed for multihop extensions of the Internet, mobile ad hoc networks (MANET), as well as wireless mesh networks. However, novel concepts for network architecture and operation are needed for a feasible deployment of mobile P2P systems due to limited availability of resources in such classes of networks.
The goal of our research comprises the design and development of mobile P2P systems as well as the optimization of P2P application scenarios through analytical modelling, simulation studies, and performance evaluation. Specifically, we are working on:
