| 摘 要： | 节点定位技术是无线传感器网络关键技术之一,介绍了节点定位技术的基本原理,提出了一种新的基于接收信号强度(RSSI)的无线传感器网络定位算法.该算法在第一阶段对节点初始位置进行初步估计,第二阶段对节点初始位置进行求精.仿真结果表明,在锚节点比例较低的情况下,该算法仍然可以实现较高的定位精度,并且与dv-distance定位算法比较,表明该算法在相同条件下精度更高.

| Abstract: | Localization is one of the critical tasks of the WSN.The basic theory of localization algorithm and a novel localization algorithm based on RSSI are presented.The localization algorithm is divided into two stages:Obtains initial location and refines the initial location.Simulation results show our algorithm achieves high localization accuracy when anchor ratio is less.Comparing with dv-distance method,this algorithm performs better in location accuracy. |
