【摘要】 节点定位是无线传感器网络中的关键技术之一。基于RSSI的定位技术是现阶段研究的热点,为解决RSSI测量方法定位误差较大的问题,提出一种将RSSI测量方法与三角形质心算法相结合的新型定位算法,该算法用三角形质心算法减小RSSI的测量误差。仿真表明该算法比基于RSSI的三边测量法定位算法的定位精度有较大提高。更多还原

【Abstract】 Node location is one of the key technologies in wireless sensor network.RSSI-based location is a hotspot in nowadays.For resolving biggish error in RSSI-based location,the paper presents a new method of location,RSSI-based triangle and centroid location,using triangle and centroid method to reduce the error of RSSI measurement.Simulation experiments prove that this algorithm can obviously improve the location accuracy compared to trilateration.更多还原
