An Improved DV-Hop Localization Algorithm Based on Jump Distance Optimization

Based on the analysis of the localization deviation of DV-Hop algorithm in wireless sensor network, the paper proposes an improved DV-Hop localization algorithm based on optimization on node average jump distance. The algorithm firstly corrects the linear distance between beacon nodes by using the path distance of beacon nodes to optimize the average jump distance between nodes. Then, unknown node uses the average jump distance of all beacon nodes as its own average jump distance. The simulation results show that compared with the traditional DV-Hop algorithm and the improved algorithm of the same type, the proposed algorithm can improve the localization accuracy more effectively under the same environment.
