无线传感器网络中一种基于簇结构的虫洞检测协议

摘要

A novel wormhole detection protocol CBWDP (cluster based wormhole detection protocol) suited for wireless sensor networks was proposed. Based on the cluster structure and new communication strategies, CBWDP can use simple methods to detect internal wormhole nodes and isolate them effectively. Also the protocol is easy to deploy without any strong external assumptions. The simulation results show that CBWDP protocol can detect and withstand wormhole attacks without reducing the network performance, thus ensuring security of the wireless sensor network environment.%提出一种新的适用于无线传感器网络的虫洞检测协议CBWDP (cluster based wormholedetection protocol).该协议在簇结构和新的通信策略基础上,能够采用简单的手段检测出内部虫洞节点并对其实现有效的隔离.同时该协议无需强的外在假设条件,具有易于部署的特性.仿真结果表明,CBWDP协议能够在不降低网络性能的同时有效检测和抵御虫洞攻击,从而保证了无线传感器网络环境的安全性.
