Improved RSSI-Based Centroid Localization Algorithm for Wireless Sensor Networks
节点定位是无线传感网络的关键技术之一,已经在军用,民用方面得到很广泛的应用.传统的质心定位算法依赖于网络、锚节点的数量、节点分布,常常定位不到目标,致使定位误差较大.为了提高定位精度,提出利用基于RSSI的质心定位算法定位未知节点,然后将已定位节点当作锚节点对未定位节点进行定位的改进算法.对算法进行仿真测试、分析验证,结果表明:定位误差减小,定位精度明显提高.
Node localization is one of the key technologies on wireless sensor network,which has been got a wide application in military and civilian areas.The positioning accuracy of centroid localization algorithm completely depends on the size and the distribution density of anchor nodes.The density of anchor nodes is small and distributed randomly in actual application,so the positioning accuracy of centroid localization algorithm is relatively low.In order to impr…查看全部>>
