摘要
无线传感器网络节点位置信息对于事件监测起到至关重要的作用,节点定位技术是无线传感器网络应用的支撑技术之一。为了提高无线传感器网络节点定位的精度,同时减少定位计算过程中的能耗,在RSSI,HCRL定位机制分析的基础上提出了一种改进型的节点定位算法:接收信号强度比定位算法(RSS-RL),通过仿真试验显示:RSS-RL定位算法不仅降低了节点定位复杂度,而且,提高了定位精度。
Node location information plays a crucial role in event-monitoring in wireless sensor networks. The technology of sensor nodes localization is one of the supporting technologies in wireless sensor networks applications. In order to improve the precision of node localization in wireless sensor networks and reduce the energy consumption in localization calculation, an improved node localization algorithm. (i. e. received signal strength ratio location,RSS-RL)is proposed base on the research of RSSI and HCRL localization algorithm. The simulation experimental results show that RSS-RL location algorithm not only reduce the node lacation complexity, but also improve the localization precision.
