Abstract: To improve the detection efficiency of clone attack, which is one of the fields of the Wireless Sensor Network(WSN) in security threats, and prolong the survival time of the network, a new clone attack detection technique, N_RAD protocol, is proposed, it introduces a new type of detection nodes that works parallels with ordinary sensor nodes. Simulation result shows that those nodes improve the detection efficiency, make the energy of the network consume equally, thus prolong the survival period. Compared to existing clone attack detection attack protocol, N-CAD protocol shows better performance.

摘要： 为提高在无线传感器网络安全威胁方面的克隆攻击技术的检测效率，延长网络的生存时间，提出一种克隆攻击检测技术，即N-CAD协议。引入一类新的检测节点，该类节点和普通传感器节点并行操作。模拟仿真结果显示，该类节点提高检测效率，使网络能量均匀消耗，延长网络的生存周期。与现有的克隆攻击检测协议相比，N-CAD协议具有较好的性能。
