摘　　要：针对现有射频能量收集网络资源分配研究局限于单个数据源场景,无法适配于多数据源网络的问题,提出了一种适用于多数据源场景的射频能量收集中继网络传输协议框架,在该框架内节点可作为源节点或中继节点传输自身数据或转发数据,并在其他节点的数据传输过程中完成射频能量收集。以协议框架为基础,分别以系统吞吐量及用户公平性为优化目标设计两种资源分配方案。仿真表明,两种方案可有效改善网络吞吐量及资源分配公平性。The majority researches on resource allocation in radio frequency(RF)energy harvesting networks are limited in single data source scenarios,which are not suitable for multiple data sources networks.To solve this problem,a resource allocation framework is proposed for multiple data sources in RF energy harvesting based wireless relay networks.By using this framework,each node can transmit data as source or relay node,and get energy from the transmission of other nodes.Based on this resource allocation framework,two schemes are designed with system throughput and user fairness as optimization objectives respectively.Simulation shows the proposed schemes can effectively improve network throughput and resource allocation fairness.
