基于RSSI跳数修正的DV-Hop改进算法
Improved DV-Hop Location Algorithm Based on Hop Correction
摘要
Abstract
To solve the problem that the hop value in traditional DV-Hop algorithm can’t represent the real distance, an improved algorithm based on RSSI is proposed. First of all,the first hop is subdivided into several grades based on RSSI,then the rest hops are modified with the distance ratio of adjacent nodes which is transformed into the corresponding relationship of the RSSI. The simulation results show that the proposed algorithm in the paper possesses of the higher location precision than the traditional algorithm without extra hardware in the same network environment.关键词
