无线传感网络允许布置多个没有物理连接关系的传感器移动节点,它可以利用多个信标节点和未知节点之间的信号发射和接收,来确定未知节点的位置.通过对NANOPAN5375定位系统的构建,并结合TOF和RSSI定位算法的研究分析,提出实现更优位置估计的TOF和RSSI融合定位算法,此算法不仅可以减小单一定位算法造成的定位误差,而且定位结果的稳定性也有所提高.%Wireless sensor networks allows the deployment of some sensors without physical connection.Through signal transmitting and receiving between beacon nodes and unknown nodes,the location of unknown nodes was determined; and based on TOF and RSSI algorithm and NANOPAN5375 positioning system,the TOF-RSSI integrated algorithm for positioning was proposed to minimize the location error caused by the single location algorithm and to improve the location stability.
