Abstract

Many peer-to-peer (P2P) applications benefit from node speciali-sation. For example, the use of supernodes, the semantic clustering of media files or the distribution of different computing tasks among nodes. We describe simulation experiments with a simple selfish re-wiring protocol (SLAC) that can spontaneously self-organise networks into internally specialized groups (or “tribes”). Peers within the tribes altruistically pool their specialisms, sharing tasks and working altruistically as a team – or “tribe”. This approach is scalable, robust and self-organising. These results have implications and applications in many disciplines and areas beyond P2P systems.
