摘　　要：促使多传感节点尽可能地收集数据是无线传感网络WSNs(wireless sensor networks)的基本要求,数据收集与能量消耗间的权衡成为WSNs的研究热点。为此,提出基于网格区域的能量感知的数据收集协议,即DGEE协议。将网络划分为同尺寸的网格区域,利用区域内节点的剩余能量和离信宿的距离信息选择区域领导者,称为区头ZL(zone leader),由区头ZL负责收集区内感测数据,考虑区头ZL的缓存器容量受限,利用区域分簇算法将区域内的节点进一步划分为多个簇,每个簇选择一个簇头CH(cluster header),向簇头传输数据,所有簇头CHs向最近的ZL或CHs传输感测的数据。仿真结果表明,与同类协议相比,DGEE协议能够有效延长网络寿命,提高吞吐量。In a WSN, it is desirable to keep many sensors active to collect data as much as possible, the trade-off between data collection and energy saving has made data gathering an interesting research field. Therefore, data gathering based on energy efficient （DGEE） scheme was proposed. The network was divided into a set of square areas called zones, and the zone leader （ZL） was chosen based on residual energy and distance to sink, and ZL collected the data from nodes in the zone. Considering the buffer limitation of ZL, the zone was divided into serval clusters, and a cluster header （CH） was elected in each cluster and nodes within a cluster sent their data to the local CH. All CHs sent their aggregated data to the ZL or CHs of the nearest zone. Simulation results show that the proposed DGEE scheme outperforms similar schemes in terms of network lifetime and throughput.
