无线传感器网络中基于RSSI的加权DV-HOP定位方法
RSSI based weighted DV-HOP localization algorithm for Wireless Sensor Networks
摘要
Abstract
The localization information is crucial for the operation of wireless sensor network(WSN).DV-Hop is a typical way for the nodes self-localization in WSNs.However, the localization accuracy of DV-HOP is very low when the disparity in distance of the adjacent nodes is very large, because the hops of the adjacent nodes always increase 1 whenever the distance is far or near.In this paper, an RSSI based weighted DV-HOP(RWDV-HOP) localization algorithm is presented.In this algorithm the hops of adjacent node is weighted by the RSS of flooding packets transmitted between adjacent node.This algorithm improves the localization accuracy compared with previous algorithms,which has been demonstrated by the simulating results.关键词
