摘　　要：提出一种基于测距的sybil攻击检测方法,各个节点通过测距找出各自邻居节点中可能为sybil节点的可疑节点,再通过邻居节点之间交换信息找出sybil节点。仿真实验表明,该方法具有如下特点:代价小,不要求高精度测距,准确性高,不引入特殊节点,不因特殊节点失效而使算法失效,不需全局信息。特别适合低成本,资源缺乏,工作在恶劣环境中的分布式无线传感器网络。Method of detecting the sybil attack based on ranging was proposed in wireless sensor network. After be located the suspect nodes by checking the neighboring nodes＇ range, the sybil node was found out through the information exchange in the neighboring nodes. Experimental results show that the method without high accurate range possess less costs and extremely precise, moreover it does not fail to calculate when there was special nodes＇ inefficiency and no overall information. The method is particularly suitable for the distributed wireless sensor network with the low-cost, lacking resources and adverse circumstance.
