Abstract

Peer-to-peer computing (P2P) has become popular recently, but the concept itself has been successfully employed for decades in computer networks and distributed systems. In a pure P2P system all instances start out as equal. Self-organization then structures the specialization process according to the capabilities of the individual instances and the needs of the entire system. As a result, self-organizing systems are often very robust (no single point of failure) and highly scalable (instances both supply and demand resources).

In this talk, Thomas Fuhrmann illustrates the workings of self-organization by describing a new routing algorithm, scalable source routing (SSR). SSR transfers a well-known P2P algorithm, Chord, into an entirely different application area:
SSR provides network layer routing, especially in large unstructured networks of resource-limited embedded devices. Here, it outperforms mobile ad hoc routing protocols such as the ad hoc on demand distance vector (AODV) routing protocol. At the same time, SSR directly provides the semantics of a structured routing overlay. Thus SSR can serve as efficient basis for the development of distributed applications and services, for example, in the field of "ambient intelligence".

Thomas Fuhrmann is with the faculty of informatics at the University of Karlsruhe. He heads a small group of currently four PhD students, established in 2003 by the Deutsche Forschungsgemeinschaft (DFG) as part of the Emmy-Noether excellence programme. Thomas pursued post-doctoral studies with Prof. Zitterbart in Karlsruhe (2001-03) and with Prof. Effelsberg in Mannheim (1998-2000). In the years 2000/01 he was with the Boston Consulting Group top management consultancy, mainly working in strategy projects in the Internet and new media industry. Thomas studied mathematical physics in Heidelberg and Cambridge (UK) and holds a PhD of the University of Heidelberg. His thesis was on computer simulations in physics.
