摘要:

针对无线传感器网络定位目标和要求,提出了一种新的利用移动导标节点广播信号来实现未知节点位置估算的方法. 1个或多个移动导标节点随机游走于网络区域,并间隔性地广播自身位置信息,未知节点利用接收到的广播信息位置估算边界线进行节点定位. 仿真实验结果表明,新算法比传统算法具有更小的计算代价和更高的可靠性、稳定性.

Abstract:

localization scheme using mobile bacon nodes is proposed. One or several mobile bacon nodes traverse the whole physical space of the sensor area by straight line or random walking mode. Mobile beacon nodes periodically broadcast their physical location information which can be received by unknown nodes. The locations of unknown nodes can be estimated from bound lines which are derived from the broadcast information. Extensive simulations show that the proposed scheme achieves significantly better performance than conventional typical algorithms in terms of computation cost, localization accuracy and convergence.

Key words: Wireless sensor networks, node localization, mobile beacons, range-free
