基于RSSI测距误差修正的改进型DV-distance差分定位算法
Improved DV-distance difference localization algorithm base on RSSI ranging error correction
摘要
Abstract
DV-distance is a localization algorithm based on multi-hop mechanism. It uses the RSSI ranging technique to measure the distance among the neighboring nodes. In order to reduce the in influence of RSSI ranging error on the positioning accuracy , it amended the ranging error of RSSI firstly, and improved the previous computing method of distance error correction among beacons secondly, which proposed an improved DV-distance difference localization algorithm based on ranging error correction. The simulation results prove that the improved algorithm not only can enhance the positioning accuracy effectively, but also can decrease the communication spending and computing complexity compared with the previous algorithms.关键词
