摘　　要：针对目前车载自组网中路由安全问题,提出一种基于经验信任的可信路由模型.该模型从客观信任的角度引入经验信任的概念作为可信度量的标准,并给出了计算节点经验信任值和信誉度的推荐方法,根据节点的经验信任值设计一种新的动态包转发规则,从而实现车载自组网的可信路由.实验结果表明,该模型较贪婪周边无状态路由(greedy perimeter stateless routing,GPSR)协议具有较高的抵抗自私节点的能力.In order to address the routing security problem of VANETs,a novel trusted routing protocol is proposed based on experienced trustiness.From the view of objective trust,a model introduces the concept of experienced trustiness as trust metrics.Also some recommendatory methods to calculate the experienced trustiness and reputation are given.And a new forwarding rule is designed according to experienced trustiness.The simulations show that the proposed trust scheme has better ability than GPSR（greedy perimeter stateless routing） protocol on accommodating selfish nodes.
