To the characteristics of large number of sensor nodes, wide area and unbalanced energy consumption in farmland Wireless Sensor Networks, an efficient data collection strategy (GCMS) based on grid clustering and a mobile sink is proposed. Firstly, cluster is divided based on virtual grid, and the cluster head is selected by considering node position and residual energy. Then, an optimal mobile path and residence time allocation mechanism for mobile sink are proposed. Finally, GCMS is simulated and compared with LEACH and GRDG. Simulation results show that GCMS can significantly prolong the network lifetime and increase the amount of data collection, especially suitable for large-scale farmland Wireless Sensor Networks.

使用移动接收器的农田WSN数据收集策略

针对农田无线传感器网络中传感器节点数量大,面积大,能耗不均衡的特点,提出了一种基于网格聚类和移动宿的高效数据收集策略。首先,基于虚拟网格划分集群,并通过考虑节点位置和剩余能量来选择集群头。然后,提出了一种针对移动宿的最优移动路径和停留时间分配机制。最后,对GCMS进行了仿真,并与LEACH和GRDG进行了比较。仿真结果表明,GCMS可以显着延长网络寿命并增加数据收集量,尤其适用于大规模农田无线传感器网络。
