基于节点信任值的安全层次路由协议

由于无线传感器网络容易受到攻击,所以保证无线传感器在网络数据传输过程中的路由安全是必要的,文中提出一种基于节点信任值、节点度和距离的簇头选举算法,进行路由主干节点的可信选举,建立安全可信的层次路由。仿真结果表明,该算法可有效评估节点的信任值,解决了节点失效或被俘获所导致的层次路由安全问题。

A Security Hierarchical Routing Protocol Based on Node Trust Value

Wireless sensor networks are susceptible to various attacks,so it is necessary to guarantee routing security during data transmission in wireless sensor networks. In this paper,a cluster head selection algorithm based on node trust value,node degree and node distance is put forward to select the backbone nodes of the network to establish a reliable hierarchical route. Simulation results show that the proposed algorithm can effectively evaluate the node value and solve the security problem of hierarchical route,which is caused by node failure or capture.
