Selective DV-Hop localization algorithm for wireless sensor networks

Sheng Meng-meng

Abstract

Aiming at large positioning error rate of conventional distance vector-hop(DV-Hop)localization algorithm,an improved DV-Hop localization algorithm called selective DV-Hop localization algorithm is put forward.SDV-Hop localization algorithm eliminates the information of long-distance beacon nodes,updates the minimum number of hops and the average hop distance.The average hop distance is corrected according to the distances error of the beacon nodes between the calculated and estimated distances.The simulation results show that the selecive DV-Hop localization algorithm can effectively reduce the average location error rate and adapt to a variety of network.
