Abstract
In order to reduce the node localization error of DV-Hop algorithm in Wireless Sensor Network, an improved algorithm based on Hybrid Artificial Bee Colony algorithm is proposed. Combining the fast convergence speed characteristics of Particle Swarm Optimization(PSO) and strong searching capability of ABC, improved algorithm firstly estimating the distance between unknown nodes and anchor-nodes by DV-Hop algorithm. Secondly, the initial position of unknown nodes was calculated by PSO. Finally, the iterative numerical method with the initial values of estimated node locations was presented by ABC. It can be concluded that the improved algorithm has obviously better locating precision than PSO and DV-Hop.
