一种有效防御虫洞攻击的方法

由于无线传感器网络节点位置信息对网络的应用起着重要的作用,且传感器网络的资源有限,因此,针对DV-Hop定位算法的安全性能较差,定位过程中极易受到破坏性极大的虫洞攻击等缺点,提出了一种有效防御DV-Hop中的虫洞攻击的方法,在DV-Hop算法中引入了检测虫洞攻击及有效防御虫洞攻击的EPWDV-Hop算法,通过Matlab仿真软件进行模拟仿真。仿真结果表明,修改后的算法不仅提高了定位精度,而且很好地预防了算法中的虫洞攻击。

Effective Defense Method for Wormhole Attack

The information about node location of wireless sensor network plays an important role to the application of network,however,it’s limited of sensor network resources,therefore,this paper puts forward a kind of effective defense method to the wormhole attack of DV-Hop,which is directed to the short comings of that the safety performance of DV-Hop algorithm poor,and the location process easily attacked by the destructive worm hole and so on.The method is that introducing EPWDV-Hop algorithm which is an effective detection defense algorithm against the wormhole attack into the DV-Hop algorithm.According to the simulation test of Matlab software,it shows that the modified algorithm can not only improve the precision of location,but also is very good to prevent the wormhole attack in algorithm.
