Research on the Evaluation Method of Relay Node Trust in Wireless Communication Network

This thesis studies the trust evaluation method of relay nodes in wireless communication networks. The relay nodes of wireless communication network play a key role in the process of data transmission, so it is very important to evaluate the trust of the relay nodes for network performance and security. In this article, through comprehensive consideration of the node power, surplus energy and bit error rate and other indicators, a relay node comprehensive trust value assessment method, the method to quantify the indicators, and use the appropriate weighting them together, calculate the relay node trust value. Through experimental simulation and analysis, the stability and feasibility of the proposed method are proved.
