The invention discloses a wireless rechargeable sensor network charger deployment method based on a greedy submodule. The method comprises the following steps: firstly, constructing a 0-1 integer programming model for solving an optimal deployment scheme of the wireless charger by taking minimum charging power as a target according to information such as a periodic moving route of each moving trolley, an electric quantity consumption rate in a moving process, residence time of each monitoring point on the route, a distance between the monitoring points and the like; and secondly, constructinga monotonically increasing sub-mode function according to the model, and finally, iteratively selecting a monitoring point position for deploying the wireless charger by adopting a greedy strategy based on the sub-mode function, thereby finally obtaining a deployment scheme. The method has better average charging power consumption performance, and can be widely applied to an application scene in which a plurality of mobile trolleys are adopted to execute periodic monitoring tasks in a wireless rechargeable sensor network.
本发明公开了一种基于贪婪子模的无线可充电传感器网络充电器部署方法,首先根据各个移动小车周期性的移动路线、移动过程中的电量消耗率、在路线上各个监测点的停留时间,以及各个监测点之间的距离等信息,通过以最小化充电功率为目标构建求解无线充电器最优部署方案的0‑1整数规划模型;其次,根据该模型构造了一个单调增的子模函数最后,采用基于该子模函数的贪婪策略迭代式地选出部署无线充电器的监测点位置,从而最终得到部署方案。本发明具有更优的平均充电功耗性能,可以广泛应用于无线可充电传感器网络中采用多个移动小车执行周期性监测任务的应用场景。
