摘要: 现有移动信号源估计算法没有综合考虑采样点之间存在的空间相关性或难以适应运动信号源,针对该问题提出一种基于空间相关性的能量优化移动单点信号重建算法。该算法对事件源进行运动预测,确定发送监测数据的最佳距离,以降低网络通信量。实验结果证明了其有效性。

Abstract: Existing estimating algorithms for mobile signal source are short of consideration for spatial correlation between spamling points or difficult to adapt moving signal source. Aiming at this problem, this paper proposes a reconstruction algorithm for energy optimization mobile point signal source based on space relativity. This algorithm dopes out the mobility of event source and ascertains the best distance for sending monitoring data to decrease network traffic. Experimental results validate the effectiveness of this algorithm.
