基于可信度的无线传感器网络安全路由算法

Trust based secure routing algorithm for wireless sensor networks

为了应对无线传感器网络节点缺乏固定基础设施、节点恶意行为难以检测等引发的安全隐患,提出了节点可信度概念,与群体智能优化算法结合,在路由中引入节点可信度,作为信息素的一个分配策略,类似MPLS的一个可信安全标签,建立可信安全路由,把恶意节点排除出网络,提供安全可信的无线传感器网络环境。仿真实验表明,对目前尚无有效抵御办法的Wormholes攻击,效果显著。

In order to deal with the safety hidden trouble caused by that the nodes in wireless sensor networks were lack of fixed infrastructure and it was hard to check the malicious behavior of the nodes, so the conception of nodes＇ trust was proposed combined with swarm intelligence optimization algorithm. It introduced nodes＇ trust as a allocation strategy of pheromone, which was similar to a reliable and secure label of MPLS, so as to set up the reliable and secure route, remove the malicious nodes from the network, and provide reliable and secure wireless sensor network environment. Simulation experiments show that it can effectively resist the wormhole attack, which is lack of effective methods to resist at present.
