DV_Hop Positioning Algorithm Based on Optimal Jump Distance and LevyPSO Algorithm

TAN Shuang;MAO Yongyi;College of Electronic Engineering,Xi'an University of Post and Telecommunications;  
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 algorithm,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 algorithm is better than the DV_Hop algorithm,the IPSODV_Hop( Improved particle swarm optimization DV_Hop) algorithm and the BDV_Hop( Based on DV_Hop) algorithm in the positioning accuracy.
