摘要
提出了一种基于RSSI的加权质心定位算法,即将RSSI方法和质心定位算法相结合,用信标节点对未知节点不同的RSSI值来确定加权因子,以提高质心算法的定位精度。加权质心定位算法计算简单,只需较少的通信开销和较低的实现复杂度,这在能量有限的网络节点中是非常重要的。
This paper provides a weighted centroid localization algorithm, based on RSSI which combines RSSI method and centriod algorithm, and weighted factor is decided by the influence of beacons to unknown nodes, to prompt localization accuracy. Weighted centroid localization algorithm featuring low communication overhead and low complexity, is our basis of localization on the energy constrained sensor nodes.
