摘　　要：为了改善无线传感器网络整体连通性,避免监控区域出现"黑洞"现象,提出了无线传感器网络节点的星型配置策略。通过RSSI和AOA相结合的协同定位算法实现了节点定位,算法中采用影射机制建立了传感器节点的平面坐标计算新方法。计算机仿真结果表明该算法能够明显提高节点的定位精度,定位精度小于1米。In order to improve connectivity for entire wireless sensor network and avoid appearing black hole on monitor and control area, a star deployment strategy was put forward. Node localization was realized through collaborative localization algorithm based on mechanism for RSSI combining with AOA, which built a new way on horizontal coordinate for sensor node. Simulation results show that the algorithm could enhance clearly localization precision less than one meter.
