中文摘要：

虫洞攻击（wormhole attack）是Ad Hoc网络中一种常见的路由攻击方法。在移动Ad Hoc网络中,虫洞攻击会严重破坏路由协议的正常运行,甚至使整个网络陷于瘫痪。基于Omnet＋＋网络仿真器设计实现了Ad Hoc网络中的虫洞攻击,并提出若干衡量虫洞攻击的指标。仿真实验表明,由于虫洞攻击节点的破坏,网络的性能明显下降。

英文摘要：

Wormhole attack is one of common routing attack methods in Ad Hoc networks.Wormhole attack will seriously damage the operation of routing protocol,or even paralyze the whole network.Based on Omnet＋ ＋ network simulator,we design and implemented wormhole attack in Ad Hoc networks,and propose a number of evaluation parameters to measure the efficiency of wormhole attack.Simulation results show that the performance of network drops dramatically due to the attack of the wormhole nodes.
