Research On Trust Model In The Mobile P2p Network

This paper puts forward a new trust model CTM (Credit Transfer Model) in the mobile P2P (Peer to Peer) network. Applying a hybrid P2P network topology structure, the CTM selects large servers in the cable network as super nodes which maintain the identity information, resource information, transaction records and trust information of ordinary nodes. The CTM simplifies the calculation of the node's trust value, identifies and suppresses the three kinds of malicious nodes in the network. And the credit transfer mechanism is proposed for the high dynamic performance of the mobile P2P network. In the simulation experiments, it shows that the model makes a good performance in the system overhead, security and transaction success rate, and can resolve some trust problem in the mobile P2P network.
