摘要
针对传统传输技术无法适用于5G通信要求的问题,提出一种基于携能和边缘缓存的5G移动通信系统传输技术。在构建的5G移动通信系统中,用户基于功率分流中继协议完成携能传输,并有选择性地将数据缓存至边缘基站,而基站利用收集的能量将数据转发至云中心。同时,以系统时延与能耗最小化设计为优化目标,通过用精英保留策略改进的遗传算法进行求解,计算得到理想的传输缓存方案。基于Matlab平台对所提技术进行实验论证,结果表明,该技术时延及能耗分别为9 s和3000 J,因此具有一定的应用前景。
Aiming at the problem that the traditional transmission technology can not meet the requirements of 5G communication,a 5G mobile communication system transmission technology based on carrying capacity and edge cache is proposed in this paper.In the 5G mobile communication system,the user completes the energy carrying transmission based on the power shunt relay protocol,selectively caches the data to the edge base station,and the base station forwards the data to the cloud center using the collected energy.The optimization objective is to minimize the system delay and energy consumption,which is solved by the improved genetic algorithm with elite retention strategy,and the ideal transmission cache scheme is calculated.The experimental results based on Matlab show that the delay and energy consumption are 9 s and 3000 J respectively,which has a certain application prospect.
