| 摘 要： | 能量限制是制约无线传感器网络发展的主要瓶颈之一，可充电无线传感器网络的出现对其发展起了巨大的作用.提出了一种基于RFID标签的无线传感器网络合作式无线充电和数据收集策略，根据通信方式的不同，具体提出了TBR和TDC两种方案，通过将网络中的节点进行分簇，并在单个簇内部署簇内移动读取器进行路径移动，对簇内的各个节点进行充电和数据收集；在簇间部署簇间移动读取器收集簇内读取器内的数据，并将数据传输给汇聚节点进行数据处理，通过分簇完成对节点充电和数据收集任务的分层处理.通过仿真验证，其结果表明合作式充电策略可应用在大型区域内部署的网络，并且保证所需的移动读取器数量最少，数据传输至汇聚节点的时延最短，TBR方案与TDC方案有效.

| Abstract: | Energy is the main problem that restricts the development of wireless sensor networks. The emergence of rechargeable sensor networks has played a significant role in its development. This paper presents a cooperative wireless charging strategy for wireless sensor networks based on RFID tags and according to different communication methods, specifically it proposes two schemes:TBR and TDC.The nodes in the network are clustered, and the nodes in the cluster are charged and the data is collected by cluster readers. Bus readers are moving among these clusters and collecting data from cluster reader. Finally, bus readers transfer the data to the sink node for data processing. By clustering the node charging and the hierarchical processing of data collection are completed. The simulation results show that the cooperative charging strategy can be applied to the network deployed in large areas, and the minimum number of mobile readers is guaranteed. The delay of data transmission to the sink nodes is the shortest, and the TBR scheme and TDC scheme are effective. |
