Abstrac: On the basis of analyzing on localization error of classical DV-Hop algorithm and average hop distance between nodes and the hop count between nodes
a particle swarm optimization( PSO) algorithm based on hop distance-weighted of hop distance credibility and hop-count optimization is proposed. Hopping credibility is the ratio of the actual distance between nodes divided by the value of node communication radius to the hopcounts between nodes
and use hop distance credibility to correct the average hop distance of node. According to credibility of hop distance is used to calculate correction factor to optimize the hopcounts. Finally
improved PSO is used to optimize the positioning location instead of least square method. Experimental results show that compared with the classical DV-Hop algorithm and the BDV-Hop algorithm
localization precision of the proposed algorithm is improved about 12 % and 2. 4 %
