A new improved DV-Hop localization algorithm

WSNs (Wireless Sensor Networks) has put forward many geographical location-based applications, enabling WSNs node location information received considerable attention. More and more researchers begin to focus on how to determine the node location information, and how to use the information in other network algorithms. Based on the characteristics of the DV-Hop, which is a very typical range-free localization algorithm , an improved scheme is proposed in this paper. Simulation results indicate that this algorithm can effectively improve the DV-Hop positioning accuracy without adding too much computing.
