A Trust Model Based on Reputation in P2P Network

A trust model is put forward based on reputation to solve trust issue between nodes in the P2P network. The trust is divided into direct trust and indirect trust in the model when the node trust is computed. And the value of the two trust as mentioned before is computed though the given method. According to the historic results and other's recommendation, node can evaluate the trust and then make a choice. Simulation results show that, the trust model can effectively resist the malicious nodes, greatly improve the success rate of information interaction and make more effective in building trust relationship between nodes.
