一种用于车载Ad Hoc网络的可信路由算法

摘要

本文在当前的信任理论研究基础之上，结合了车载网络固有的特点，创建了用于评估节点行为的信任模型并提出了基于信任模型的可信路由算法（Trust Mode Based Trust Routing Protocol）。通过分别对两种仿真环境（使用可信路由算法的VANET环境和传统的VANET环境）进行NS2仿真并对结果进行比较，验证了可信路由算法可以实现降低恶意节点使用率并提高路由生存期的目的。%Based on the investigation of the current Trust Theory and the inherent characteristics of vehicle networks, we proposed the trust model for evaluating the nodes’ behavior and developed the trusted routing algorithm based on the proposed trust model (Trust Mode Based Trust Routing Protocol). In order to verify the correctness and effectiveness of the algorithm, we designed two simulation Simulations are then conducted by using NS2 in two environments:VANET environment based the trusted routing algorithm and traditional VANET environment. From the simulation results, it is proved that the trusted routing algorithm can reduce the usage of the malicious nodes and improve the survival time of specific route.
