摘要
为解决传统质心算法定位精度过低的问题,引入VIRE算法,利用信号传播模型在定位区域内构造虚拟参考标签的RSSI信息,提出一种将VIRE系统与传统质心算法相结合的改进算法。仿真结果表明,在计算复杂度提高的情况下,改进算法的定位精度较传统质心算法提高了33%。
For improving the accuracy of centroid localization,a modified algorithm is introduced in this paper.Based on the VIRE algorithm and the RSSI information of virtual reference tags established by signal transmission model in location area,an improved algorithm was proposed,which is the combination of VIRE system and the original centroid algorithm.Although the computational complexity has increased,the simulation results show that the accuracy of positioning has been further improved to 33％ by this algorithm compared to the original centroid algorithm.
