移动边缘计算辅助的数能协同传输网络节能算法研究

Research on Energy Saving Algorithm of Data Cooperative Transmission Network Assisted By Mobile Edge Computing

物联网终端设备在投入使用后会自动执行数据采集、数据计算等任务,最终将计算结果上传至物联网的网关或者基站。但是,一方面由于越来越多的物联网终端设备开始采用电池供电,在物联网终端设备这一端执行复杂的算法或任务会消耗掉大量的能量;另一方面随着物联网中应用的需求日趋复杂,精简设计的物联网终端设备上的计算资源已经越来越不能满足日趋复杂的计算需求。因此,提出了移动边缘计算辅助的数能协同传输网络。该网络中物联网终端设备可以将自身的计算任务全部卸载至移动边缘计算服务器,自身只需要执行简单的、低能耗的任务。在保证系统通信与计算需求的前提下,通过节能算法的设计,达到了最小化协同传输系统总能耗的优化目标。

The terminal equipment of IoT(Internet of Things)will automatically perform data acquisition,data calculation and other tasks after being put into use,and finally upload the calculation results to the gateway or base station of IoT.However,on the one hand,as more and more IoT terminal equipments begin to use battery power,executing complex algorithms or tasks at this end will consume a lot of energy;on the other hand,as the requirements of applications in IoT are becoming more and more complex,the computing resources on the streamlined designed IoT terminal equipments become increasingly insufficient to meet the complex computing requirements.Therefore,this paper proposes a mobile edge computingassisted data cooperative transmission network.IoT terminal equipments in this network can offload all their own computing tasks to mobile edge computing servers,performing only simple,low-energy tasks themselves.On the premise of ensuring the communication and computing requirements of the system,it aims to reduce the total energy consumption of the co-transmission system through the design of energy-saving algorithms.
