提出了一种新的分布式非测距定位算法--多边形重叠可能区域(POPA)算法,用于精确定位未知节点。首先,对于一个未知的节点,从理论上定义其可能的本地化区域(PLA),其第n跳锚邻居的虚拟辐射区域被引入。然后,一个有效的区域分裂算法,以简化和加快计算的可能定位区域。仿真结果表明,定位误差可以控制在20%以内的现成的设备。
A novel distributed range-free localisation algorithm, named polygonal overlapped possible area (POPA), is proposed to accurately localise an unknown node. First, for an unknown node, to theoretically define its possible localisation area (PLA), virtual radiation regions of its n th-hop anchor neighbours are introduced. Then an effective area-splitting algorithm is employed to simplify and speed up the computation of the possible localisation area. Simulation shows localisation error can be controlled within 20% with off-the-shelf devices.
