摘要
文章提出了一种利用无线传感器网络无线信号接收强度(RSSI)和移动锚节点轨迹来获得待定节点位置的算法。该算法在有多个可移动锚节点的情况下,定位将会更加高效。在定位阶段,通过RSSI测得锚节点到待定节点的距离,并利用三个以上移动锚节点的坐标(包括三个)来求解圆的方程,计算出待定节点的位置。
Based on Received Signal Strength Indicator （RSSI） of wireless sensor network, a mobile anchor node and a center of a circlelocalization algorithms is presented. If there are several mobile anchor noeds, this algorithm will be more efficiency. In the positioning phase, the distance measured by RSSI from node to node, the anchor nodes loactions will be used in order to solving the circle and work out the location of the pending node.
