摘    要: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.

关 键 词:无线Mesh网  多径源路由  路由安全  信誉机制

Abstract: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.
Keywords:wireless mesh network  multipath source routing  routing security  reputation mechanism
