摘要

在传感器网络中，车辆位置主要由传感器组确定。每个传感器都配备了天线阵列来测量来自移动车辆的到达角度。传感器处理的阵列信号复杂，能耗大。提出了一种不需要处理单元的传感器定位方案。此外，还设计了一种计算效率高的到达角估计算法。与基于传感器的方法相比，该方法减轻了对传感器尺寸和能耗的要求，减少了通信和计算开销。仿真结果表明，该方法适用于移动车辆定位。

An energy-computation-efficient (ECE) method for mobile localization in sensor networks

In sensor network, vehicle location is mostly determined by sensor group. Each sensor is equipped with an antenna array to measure the angle of arrival from a mobile vehicle. Complicated array signals are processed at sensors, which leads to large energy consumption. This paper presents a novel localization scheme where processing unit is not required at sensors. In addition, a computation efficient algorithm is designed for angle of arrival estimation. Compared with sensor-based approaches, this method relieves the requirements of sensor size and energy consumption and reduces communication and computation overhead. The simulation results show that the proposed method is potentially suitable for mobile vehicle localization.
