A Mobile Beacon Assisted Node Localization Algorithm Based on Increment Localization

针对网络中可能有少量节点难以接收足够定位信息的情况,提出一种基于增量定位的移动信标辅助节点定位算法。该算法初步考虑节点之间的协作,选取部分节点对接收信息进行转发。仿真结果表明,在移动信标的路径长度和通信半径不变的情况下,该方法可获取较高的定位覆盖率,适用于信标路径间距较大的场合。

In actual environment, some nodes may be difficult to localize by lack of sufficient localization information. Aim at the problem, a mobile beacon-assisted node localization algorithm based on increment is proposed. The cooperation among nodes is considered and some nodes are selected to retransmit the received messages from the mobile beacon. Simulation results show that the algorithm increases the The algorithm is suitahle for the situation that the space
