检测多径路由Ad Hoc网络中的虫洞攻击

Detecting Wormhole Attacks in Multi-path Ad Hoc Networks

多径路由技术的出现为AdHoc网络解决带宽狭窄和不可靠的连接提供了新的选择,而在虫洞攻击下,会造成多径路由网络信息丢失,严重的甚至会导致网络瘫痪,本文提出了一种新的方法,对数据包中具有的路由信息进行统计分析,并和样本数据进行比较,来判断网络是否受到虫洞攻击并定位恶意节点的位置,从而避免了AdHoc网络受到虫洞攻击的危害。模拟试验的结果证明本方案有效的检测到了虫洞攻击并定位网络中的恶意节点。

The emergence of muhi-path techniques in Ad Hoc network is a new choice because muhi-path routing provides means to combat the effect of narrow bandwidth and unreliable wireless links. But the multi-path network under wormhole attack will drop information. More seriously, it will cause network collapse. This paper proposes a new scheme by statistically analyzing the information collected by packets of multi-path network and compared with samples to detect wormhole attacks and identify attackers＇ location. This scheme make Ad Hoc network keep away from the harm caused by wormhole attacks. Simulation results demonstrate that it successfully deteets wormhole attacks and locates the malicious nodes in Ad Hoc network .
