基于信誉机制的多径源路由协议研究

为了提高无线Mesh网中多径源路由协议（MSR）的路由安全，在原协议基础上引入了信誉机制，在每个节点上维护1个信誉表．源节点在路由建立前对节点信誉度的进行验证，当节点的信誉度值低于限定值时，就孤立该转发节点．以此建立多个安全的路由路径，提高WMN中路由的安全．仿真结果表明：在包含恶意节点的WMN中，改进后的路由协议有较好分组投递率和较低的端到端时延．

Study of multipath source routing protocol based on reputation mechanism

To enhance the routing security of MSR （ Muhipath Source Routing） in WMN,this paper introduces the reputation mechanism which maintains a reputation table at each node in MSR system. Before setting up the routing, the source node will verify the reputation degree of each node. If a node＇s reputation degree is lower than the limited value, it will be isolated. As a result, several safe routing paths are established between the source and destination nodes. Thus the routing security in WMN is improved. Simulation results show that the improved routing protocol has a better packet delivery fraction and lower end-to-end delay in WMN that contains hostile nodes.
