An improved DV-hop algorithm based on iterative computation for wireless sensor network localization

Efficient localization algorithm is a research focus in the field of wireless sensor network (WSN). Nowadays, DV-hop algorithm is one of the most important range-free localization algorithms. In this paper, we analyse the fundamental of DV-hop algorithm and propose a novel improved DV-hop algorithm based on iterative computation. By simulations, the results show the proposed algorithm gives better accuracy than the original programming localization.
