A Reputation Model base on Transactions in Peer-to-Peer Networks

We present a method to compute global reputation values of peers in P2P based on the transaction between peers in the past.The traditional reputation model can hardly solve the collusion between Evil Peers. In this paper we compute the simlarity between Peers in the networks, in the global reputation model Unsimularity peers has more credibly then simularity peers. The simulation show that the model is availability and feasibility. Keywords : Reputation P2P Transactions
