A Novel Localization Algorithm for Wireless Sensor Network Using Two-hop Beacon Nodes
The location estimation of sensor nodes is a fundamental and essential issue for wireless sensor networks (WSNs), because the gathered data is meaningful only when the location information of the sensor nodes is known. In this paper, we proposed a novel localization algorithm. In the proposed scheme, we first estimate the location of sensor nodes using Convex Position Estimation (CPE), and then refine the location of sensor nodes using the location of the two-hop beacon nodes. Simulation shows that compared with convex localization algorithm, the proposed localization algorithm can enhance the localization accuracy efficiently.
