摘要：To improve the resource location efficiency and guarantee resource download quality of nodes in P2P systems, we propose a node Interest bias based P2P Interest domain partition mechanism, give the concept of Interest similarity as well as its computation method, and then present an adaptive P2P topology evolvement model ISPT based on interest similarity ISPT. In ISPT, by computing interest similarity of each other, nodes with similar interest bias and service trust value are connected as neighbors. Since nodes that have similar interest are more likely to share resources, ISPT improves node resource query response efficiency, and provides an incentive mechanism to encourage node offer more contribution so as to get better service. Simulation results show that ISPT improves the efficiency and security of P2P topology effectively.
