摘要

传感器节点的位置估计是无线传感器网络(WSNs)的基础和核心问题，因为只有当传感器节点的位置信息已知时，采集到的数据才有意义。本文提出了一种新的定位算法。在该方案中，我们首先使用凸位置估计(CPE)来估计传感器节点的位置，然后使用两跳信标节点的位置来改进传感器节点的位置。仿真结果表明，与凸定位算法相比，该算法能有效提高定位精度。

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.
