| 摘 要： | 节点自定位一直是无线传感器网络中的关键,基于接收信号强度指示(RSSI)的定位技术是目前的研究热点,但由于多径、绕射、非视距的影响,产生的距离误差较大.提出了基于RSSI校正的三角形质心定位算法,该算法简单,不增加通信开销,无需硬件扩展.仿真实验表明:该算法较其他算法大大提高精度,适合通信开销小、硬件要求低的无线传感器网络节点.

| Abstract: | Node self-localization has been the key in wireless sensor networks(WSNs).Received signal strength indication(RSSI)-based positioning technology is the current research focus,but errors influenced by factors such as multipath,diffraction,non-line-of-sight,distance is large.Triangle centroid algorithm based on the RSSI correction is presented.It is simple,does not increase communication expense without hardware expand.The simulation results show that this algorithm greatly improved precision compared with ot... |
