Abstract—In most of the current trust model, the evaluation of whether an entity is trust is different to different judger. The reason of this phenomenon is that different judger use the different standard in its opinion. So the evaluation lack of convincing, are not well describe the relationship between two parties. In response to these issues, drawing on the trust relationship between human societies, the introduction of the domain and domain trust, building the trust evaluation model based on service satisfaction. In every domain according to the service of the node itself, abstracting representative multiple service attributes from the trusted relationship of the node service, service requester comprehensive evaluates multiple service attributes provided by service provider based on personal interest, and combines with the trust value, decide whether to trade finally; after the transaction, service request calculates QoS(quality of service) difference degree according to actual QoS and service provider’ own QoS claimed to judge the credibility of service provider, then gives corresponding rewards and punishment and trust update. The simulation results show that the model can more accurate assessment of the trust entity, to some extent effective against malicious attacks, which proves the validity and accuracy of the model.
