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 realize complex large-scale monitoring and tracking tasks in a wide range of applications. The self-localization of nodes is a key technology in sensor networks. Based on the two-dimensional centroid localization algorithm, a three-dimensional centroid localization algorithm is proposed. The results of C ++ simulation show that the two-dimensional centroid localization algorithm does not significantly increase the complexity of the algorithm and does not affect the coverage, Volume and two-dimensional positioning error, but it can provide three-dimensional positioning coordinate information.
