基于最优跳距和LevyPSO算法的DV_Hop定位算法
DV_Hop Positioning Algorithm Based on Optimal Jump Distance and LevyPSO Algorithm
摘要
Abstract
Aiming at the problem of low location accuracy in DV_Hop(distance vector-hop)algorithm,this paper proposed a wireless sensor network localization algorithm based on optimal hop distance algorithm and LevyPSO al-gorithm,namely OLPDV_Hop( Optimal jump distance and Levy particle swarm optimization DV_Hop) . First of all, the single hop average error correction average hop distance,and then used the average hop anchor node received from the estimation of the distance between nodes,so that the estimated distance could be optimized,finally using the LevyPSO algorithm instead of least square method of unknown node location, LevyPSO algorithm using Levy flight change particle movement direction to avoid falling into a local optimum,and the greedy update the evaluation strategy of the optimal solution,finally got the global optimal. The simulation results show that the OLPDV_Hop al-gorithm is better than the DV_Hop algorithm,the IPSODV_Hop( Improved particle swarm optimization DV_Hop) al-gorithm and the BDV_Hop( Based on DV_Hop) algorithm in the positioning accuracy.关键词
