无线传感器网络(WSN)副本极易被攻击和破坏.为此,提出一种WSN副本攻击的巡逻检测算法,利用移动节点作为巡逻者,寻找并排除所有具有相同ID的副本.针对普通节点和巡逻节点,分别提出副本节点检测算法和副本巡逻者检测算法.安全性与性能分析结果表明,与同类算法相比,该算法在保证检测性能的同时,具有较低的通信成本,可以延长网络寿命.%Replica in Wireless Sensor Network(WSN) is vulnerable to be attacked and destroyed. Aiming at the problem, this paper proposes a patrol detection algorithm for replica attacks in WSN, which uses mobile nodes as patrollers to find and exclude all replicas with the same ID. Two detection algorithms are presented, including replica node detection algorithm and replica patrolier detection algorithm. Security and performance analysis results show that the algorithm ensures the detection performance in the meantime, has lower communication cost and can prolong network lifetime in comparison with existing detection algorithms.
