摘要
针对Ad Hoc网络中虫洞检测方法带来的高时延和能耗问题,提出一种低时延和能耗的轻量级虫洞检测方法。即在节点查询路由后,利用路由节点的邻居数目,找出可能受虫洞影响节点的集合,同时依据路由节点的某个邻居节点的路由信息,进一步确定路由节点是否受虫洞影响。仿真结果表明,该方法可有效减少虫洞检测中的路由查询次数,并且与DeWorm和E2SIW方法相比,可有效减少时间延迟和能量消耗。
To solve high energy and time delay cost problems caused by wormhole detection in Ad Hoc networks, a light- weighted wormhole detection method, using less time delay and energy, was proposed. The method used the neighbor number of routing nodes to get a set of abnormal nodes and then detect the presence of a wormhole by using the neighbor information of abnormal node when routing process was completed. The simulation results show that the proposed method can detect wormhole with less number of routing query. Compared with the DeWorm （ Detect Wormhole） method and the E2SIW （ Energy Efficient Scheme Immune to Wormhole attacks） method, it effectively reduces the time delay cost and energy cost.
