WonGoo: a pure peer-to-peer full text information retrieval system based on semantic overlay networks

Compared with centralized information retrieval system, peer-to-peer (P2P) full text information retrieval system is more scalable, cost effective, fault tolerant, and powerful to search scarce content at the edge of Internet. However, P2P full text search is a very challenging problem, and the traditional broadcast ways are quite ineffective. We present a P2P full text information retrieval system WonGoo that is based on P2P structured overlay networks. We also implement a simulation program and test the performance of the system. Experimental results show that WonGoo is a steady system with high recall, good load balance and low resource usage.
