摘要： 针对Ad Hoc网络中的虫洞攻击，根据最优链路状态路由(OLSR)协议的运行特点，提出检测伪邻居的HELLO间隔分布式算法(HIDA)。仿真结果表明，在网络平均节点数大于4、节点随机最大移动速率大于2 m/s时，HIDA算法能达到80%以上的虫洞攻击检测率。

Abstract: Aiming at the wormhole attack in Ad Hoc network, according to Optimized Link State Routing(OLSR) protocol, this paper presents a HELLO Interval Distributed Algorithm(HIDA) to detect fake neighbor. Simulation results show that HIDA has wormhole attack detection rate above 80% when network average node number is greater than 4, node random maximal migration rate is greater than 2 m/s.
