| description | Positioning is a widely used technology in wireless sensor network (WSN). For range-based positioning, the positioning accuracy is proportional to positioning accuracy. As a low-cost positioning method, the range-based received signal strength indicator (RSSI) method realizes good positioning accuracy. However, positioning error may arise from the complex model of loss path, complicated changes of environment, and oscillation of signal. To eliminate the positioning error, this study presents a hybrid RSSI method for the WSN based on weighted centroid and adaptive threshold selection. The causes of positioning error were analyzed in details, and the positioning strategy was thus improved. Simulation results show that our method achieves better positioning accuracy and higher stability than benchmark positioning methods. |
