基于可靠骨干网的Ad Hoc网络安全路由协议

Secure Routing Protocol Based on Reliable Backbone in Ad Hoc Networks

针对Ad Hoc组网的安全路由协议设计问题,提出一种基于可靠骨干网的Ad Hoc网络安全路由协议。引入信任评估机制对网络节点进行评估,依据评估结果选取可信节点作为网络骨干节点,同时将低于信任阈值的恶意节点进行隔离,以骨干节点为簇头对网络进行安全分簇,簇头节点及簇内成员节点间构成可靠骨干网,基于可靠骨干网进行安全路由协议的设计。仿真实验表明,与AODV等路由协议相比,本协议在满足安全性的同时能达到更优的网络性能。

In order to get the secure routing in Ad Hoc networks,based on the reliable backbone networks,a secure routing protocol was proposed. The trust evaluation mechanism was introduced to select the trust backbone nodes,the behavior of the node was evaluated and the malicious nodes was isolated from the network. Then the network was clustered by backbone nodes which act as the cluster head nodes. The reliable backbone network was established by cluster head nodes and cluster member nodes. At last,the secure routing protocol was established based on the reliable backbone network. Simulation results showed that the proposed secure routing protocol can improve the network performance significantly even under attacking when compared with other typical routing protocols.
