Application research about wireless sensor network nodes location algorithm based on improved RSSI
研究无线传感器网络节点定位问题.接收信号强度值(RSSI)直接影响无线传感器网络节点定位准确度,而现有定位算法没有考虑锚节点的RSSI消息,造成节点定位精度低.为了提高无线传感器网络节点的定位精度,提出了一种基于RSSI的质心定位算法.首先通过无线信号强度计算出节点间RSSI值,然后把RSSI值转换成质心算法权值,最后采用质心定位算法对待测节点位置进行估计,获得节点的准确位置.仿真实验结果表明,与现有质心定位算法相比,基于RSSI的质心定位算法在…查看全部>>
This paper researched wireless sensor network node location. Wireless network anchor nodes deployed uneven, and density was small, the traditional localization algorithms had not considered RSSI news anchor node localization, location accuracy was low. In order to improve the location accuracy, this paper proposed a location algorithm based on the RSSI. Firstly, it calculated RSSI value through wireless signal strength between the nodes. And then conve…查看全部>>
