摘要
无线传感器网络的目标定位提出了一种运用接收的能量来实现目标定位的方法。与其他定位算法对比,它有一定的优越性,但能量算法自身也有一定的局限性。本文在比较基于能量的各种算法的基础上提出了建立目标函数,用梯度法实现定位的算法。
A new method of target localization in wireless sensor network was proposed which took advantage of the energy received. Compared with other methods of target localization, it is advantaged in some aspects, but it is disadvantaged in some aspects itself. Based on the comparison of different algorithms of energy,we create a target function, and use grads method to realize localization.
