摘要: 针对正六边形网格定位算法定位误差不均匀和正方形网格定位算法冗余节点过多等问题,提出了一种新的基于锚节点等边三角形分布的质心定位算法.该算法运用网格划分理论,验证这种网格划分的合理性;通过实验,探索各项参数对于这种新算法的影响.仿真结果表明,该算法在结构简单、硬件投入和功耗相对较少的情况下,提高了节点定位的精确度.但该算法在锚节点数量和计算量上都有所增加,有待下一步改进.Abstract: Aiming at the problems of error uneveness in regular hexagon grid location algorithm and nodes redundancy in the square grid positioning algorithm, a new centroid localization algorithm based on the anchor nodes equilateral triangular distribution was proposed. The algorithm used the theory of meshing to verify the rationality of the grid and explored the effects of parameter on this new algorithm through experiments. The simulation results showed that the algorithm in the case of simple structure, relatively small hardware investment and power consumption, improved node localization accuracy. However, the number of anchor nodes and computation have increased in this algorithm, subject to future improvements.
