Trust Evaluation Based Reliable Routing in Wireless Mesh Network

The transmission reliability of wireless mesh network relies on the cooperative and the trusted between the network nodes. To reliable route and forward data packets, it is important to evaluate the trustworthiness of nodes in network But due to the nature of wireless mesh network, the sample space of evidence which is used to evaluate trust may be incomplete or unreliable. So the existing trust evaluation model could not apply to it unalterably. A novel trust evaluation based reliable routing scheme is proposed to solve this problem. It evaluates the trust value of nodes through a novel uncertainty measurement infinitesimal algorithm and discovers reliable routes according to the trust value of nodes. The simulation shows that the proposed model is able to evaluate the trustworthiness of nodes effectively and improve the transmission reliability of the network.
