Heuristic resource discovery in p2p network

How to discovery resources effectively in a distributed system without centralized index services has been gained great concerns. In this paper, we proposed a modified chord algorithm, built a semantic P2P network. In research, we generated the resource's index by its semantic knowledge, and dynamically established routes between peers by the accumulated knowledge from their received search results. Experiment results showed that our prototype system has improved efficiency than the classic Chord. Furthermore, we also proposed a method of information sharing to accelerate the route establishing process.
