A trusted routing algorithm based on D-S evidence theory combined with physical layer security

Abstract

With the rapid development of the communication technology, the traditional routing algorithms which only consider functional QoS metrics are difficult to meet the needs of applications. In this paper, we propose a trusted routing algorithm to overcome this problem. First, we propose a trust evaluation model of service instances based on the Dempster-Shafer theory combined with physical layer security, and then the trusted routing algorithm is proposed by using this model to improve the traditional routing algorithms. The simulation results show that the proposed trusted routing algorithm can effectively improve the success rate of routing and the performance of the QoS metrics.
