无线网状网中基于D-S证据理论的可信路由

Trusted routing based on D-S evidence theory in wireless mesh network

结合Dempster-Shafer(D-S)证据理论,提出了一个信任评估模型;同时,在AODV的基础上,给出了一个可信的路由协议T-AODV,该路由协议根据节点的信任值选择可信的路由进行数据传输。仿真结果表明,所提机制能够有效地监测和隔离恶意节点,抵御攻击,能够提高网络的可靠性、顽健性以及安全性。

Combined with Dempster-Shafer （D-S） evidence theory, a trust evaluation model was given, meanwhile, a trusted routing—— T-AODV was also proposed which built trusted routings according to the trustworthiness of nodes calculated by the proposed trust evaluation model. Simulation results show that the proposed scheme can detect and isolate malicious nodes efficiently and resist attacks to some extent and improve the reliability, robustness and security of the over all network effectively.
