摘要

为了解决定位问题，本文提出了一种定向天线接收信号强度(RSS- da)方案，该方案利用已经知道坐标的移动锚节点在数据传输中加入接收信号强度(RSS)测量。在传感器节点中信标个数符合终止阈值，估计的位置使用RSS算法和两圆相交算法进行计算。仿真结果表明，本文提出的传感器节点定位方案基于RSS测量下的移动锚节点，而不是基于DIR定位方案，减少了定位误差，实现了低能耗。

An Improving Localization Scheme Using Mobile Anchors with Directional Antennas in Wireless Sensor Networks

To solve the location issue, in this paper, we proposed a Received Signal Strength for Directional Antenna (RSS-DA) scheme, it uses the mobile anchor nodes that already know the coordinates to join the Received Signal Strength (RSS) measurement in the data transmission. The number of beacons conforms to the terminated threshold in the sensor nodes, the estimated locations are used the RSS algorithm and the two-circle intersection algorithm for the calculations. Simulation results show that our proposed scheme of the sensor nodes are based in a mobile anchor node under RSS measurement, rather than the DIR localization scheme, to reduce the location error and achieve low energy consumption.
