Abstract

Wireless sensor networks (WSN) have wide applicability to many important applications including environmental monitoring, military applications and disaster management, etc. In many applications, sensors are assumed to know their absolute locations. Some localization methods of WSN have been proposed. In these methods, nodes equipped with GPS to get precise location information, namely the anchor nodes, are employed to derive the locations of other nodes. Most of the recent work focuses on increasing the accuracy in position estimation. In this paper, aiming at the high communication cost and average positioning error of DV-hop algorithm, an advanced algorithm which is called ADV-hop algorithm is proposed. Simulations are made by the network simulator NS2. The simulation results show that ADV-hop algorithm has lower communication cost and smaller average positioning error than DV-hop algorithm, which makes ADV-hop algorithm more suitable for the node location of WSN.
