摘要
无线传感器网络可以在广泛的应用领域内实现复杂的大规模监测和追踪任务,而节点的自定位技术是传感器网络的关键技术。文章以二维质心定位算法为基础,提出了三维质心定位算法,用C++仿真结果表明,二维质心定位算法升级为三维质心定位算法没有明显增加算法的复杂性,也不影响覆盖率、通信报文量和二维定位误差,但却能提供三维定位坐标信息。
Wireless sensor networks can be widely used in the field of complicated large-scale monitoring and tracking, and self-localization of every sensor is a key enabling technology for wireless sensor networks. Based on 2D-Centroid localization algorithm, 3D-Centroid localization algorithm is proposed, Simulation results by using C＋＋ show that the promotion of 2D-Centroid localization algorithm to 3D-Centroid localization algorithm has not obviously increased the complexity of the algorithm, also not affected the coverage, the number of messages exchanged and 2D localization error, while the 3D localization coordinate information is provided.
