一种无线传感器网络中的虫洞攻击检测算法

A Wormhole Attack Detection Algorithm in Wireless Sensor Networks

分析了无线传感器网络中的虫洞攻击的特点,根据某些路径变短和某些节点的邻居数增加的特点,提出了一种无线传感器网络中虫洞攻击的检测算法.首先在边界部署一些源、目的节点对,然后利用路由发现过程来发现跳数异常少的可疑路由.通过检查邻居节点数来检测可疑路径上的每个节点,如果节点的邻居数增加,则该节点为被感染节点,网络中存在虫洞攻击.被感染节点被从网络中隔离,以避免更大的破坏.实验结果表明该算法具有较低的漏报率和较高的准确性.

Features of wormhole attacks in wireless sensor networks were analyzed. Accorcllng to the features that some routes may be shortened and the number of neighbors of some nodes may be increased, a detection algorithm was proposed to detect wormhole attacks in wireless sensor networks. Some source and destination （SD） node pairs were firstly deployed at the edge zone. Then the route discovery process was launched to find dubious route with abnormally fewer hops. After that, each node on the dubious paths was detected by checking the number of its neighbors. If such a node had more neighbors, it could be made sure that the node was infected and there was a wormhole attack in the network. The infected nodes would be isolated from the network to avoid more damages. Experimental results showed that the proposed algorithm has low false positive and high accuracy
