Abstract—In order to improve the Peer-to-Peer (P2P) network resource locating efficiency and isolate malicious peers, a topology adjustment algorithm for unstructured P2P networks is proposed. TTL (time-to-live) value for each neighbor has been set up and adjusted; specific information on the query path is recorded; a topology adjustment algorithm is given. The topology adjustment algorithm is evaluated by peer shortest path, simulation and analysis show that the topology adjustment algorithm can isolate malicious peers to the network edge, and improve service quality of P2P networks.

Index Terms—Peer-to-Peer; unstructured; topology; shortest path
