摘要:
无线传感器网络基于声音能量的目标定位法中，非线性方程定位算法运算速度较快，占用资源小，但测量噪声使得方程容易出现无解的情况。论文从去除噪声的角度，采用增加采样次数和选择声音信号最大值求解的方法进行了改进，解决了方程法经常无解的缺点，实现了针对单目标的方程法定位估计。该方法易于实现，当网络中节点数较多时，只需通过一个方程组求解，保持了运算速度快的特点，仿真结果表明当节点数不多时该算法也能达到较好的估计准确度
Abstract:
Nonlinear equation algorithm spends less calculation time and less resource among the method for target location using acoustic energy measurement in wireless sensor network. But the nonlinear equation is easy to be no solution because of measurement noise. From the angle of decreasing the noise, adding samples and searching the maximum values of energy are used to resolve the equation to reduce the case of no solution in target location. Location estimation based on the nonfinear equation is completed for single target. The method is simple and is easily realized. The solution also can be given only through one equation set when there are many nodes in wireless sensor network. It spends less calculation time. Simulation results show that it has a good performance of estimation with a few nodes
