| 摘 要： | 从硬件设计入手，介绍了自主设计的以片上系统（SOC）STM32W108为核心的WSN节点，在此基础上采用了一种基于RSSI的加权质心定位算法实现了节点的自定位。该算法将RSSI测距和质心定位算法相结合，用测得的RSSI值作为质心定位的加权因子，合理体现了不同锚节点对定位未知节点的约束力。通过测试证明，该定位方法在较少的通信开销情况下具有较高的定位精度，且易于实现。

| Abstract: | This paper begins from hardware design,then introduces the independent design of WSN nodes whose core is STM32W108. Based on the design of hardware and adopted a weighted centroid localization algorithm which based on RSSI,we realize the localization of nodes. The algorithm was realized by combined RSSI ranging with centroid localization algorithm, and reflected the force of constraint of different anchor nodes to unknown nodes by using the RSSI as weight coefficient. The test results show that the weighted eentroid localization algorithm based on RSSI has higher localization accuracy with less communication cost and realizes easily. |
