摘要
无线传感器网络技术近年来发展非常迅猛,然而实际通信环境非常复杂,而且充满攻击和对抗,网络节点的正确位置信息是构建系统、维护网络、目标跟踪和事件定位等关键技术实现的基础,定位的安全性至关重要。着重研究了基于接收信号强度指示(RSSI)原理抗女巫攻击的无线传感网络安全定位系统的编码技术和定位方法,并对相关算法进行了仿真分析。通过结果可知,改进后的编码和定位算法结构相对简单,对系统的硬件依赖小,抗攻击能力提高。
Along with the profound development of wireless sensor network, and in the environment of complicated and full of counteract communication, correct localization information of node is the prerequisite and basis of accomplishing some modules, such as construction of sensor network, maintenance, incident localization, target tracking. Thus, the localization security becomes a key technique. The paper puts an emphasis on a code method and a location algorithm based on RSSI Sybil attack detection for wireless sensor network, and does a simulation analysis. The results show that the improved RSSI location method has little dependence on hardware and the antiattack ability has been improved obviously.
