Range-Free Localization Algorithm Based on Mass Spring Model for Wireless Sensor Networks
摘要
Abstract
The range-free localization algorithm has attracted much attention in wireless sensor networks due to its low power consumption and low cost,but its low positioning accuracy has limited its application. This paper proposes a high-accuracy range-free localization algorithm L-MSM( Localization based on Mass Spring Model) . The algorithm first uses the centroid algorithm which has low complexity and little communication overhead for coarse positioning, then adopts modified mass spring model for iterative refinement,which makes the nodes in clusters because of the drawback of centroid algorithm spread out and approach the actual position. The simulation results indicate that the L-MSM algorithm can significantly improve the positioning accuracy compared to the centroid algorithm when the communication radius is small.关键词
