A Trust Model Based on Dual Trust Requirement For Mp2p Network
Combining the characteristics of Mobile P2P (MP2P) network and the node needs of trust, a trust model based on dual trust requirement (DTRTM) is proposed.In this model, the node requirement of trust is divided into two types: resource trust requirement and service trust requirement, resource trust value and service trust value are used to describe their credibility respectively.Using the node feature of strong dynamic, we introduce the familiarity of network scenarios and resources to portray the node reliability of resource.Using the node feature of weak stability, we introduce the credibility of service and the stability of service to portray the node reliability of service.Simulation experiments show that DTRTM can reduce the impact of collusion and restrain free ride behaviors effectively.It also can reduce the overhead of trust evaluation,improve the rationality of trust value, increase successful transaction rate in MP2P network.
