摘要
如何延长网络寿命是无线传感网络中一个关键问题,为此提出了基于全向无线充电模型的动态调度优化方法,目标是最大化网络寿命。文章对充电小车的停止点选择进行了分析,根据全向无线充电模型的覆盖范围确定了充电小车的停止区域,再以最大化节点接收功率之和为优化目标确定每个区域内的最佳停止点。实验结果表明,所提出的方法能够延长网络寿命,与MRCR(Multi-node Renewable based on Charging Range)算法相比,可延长网络寿命约3%~113%。
How to extend network life is a key issue in wireless sensor networks. In order to solve this problem, a dynamic scheduling strategy based on the omnidirectional wireless charging model is proposed, with the goal of maximizing network lifetime. In this paper, the selection of stop point of charging car is analyzed, and according to the coverage of omnidirectional wireless charging model, the stop area of charging car is determined, and then the optimal stop point in each area is determined by maximizing the sum of receiving power of nodes. The experiment results show that the proposed method can prolong the network lifetime, which is about 3%~113% longer than MRCR(Multi-node Renewable Based on Charging Range) algorithm.
