摘要

为了提高移动边缘计算（mobile edge computing，MEC）网络的频谱效率，满足大量用户的服务需求，建立了基于非正交多址接入（non-orthogonal multiple access，NOMA）的超密集MEC系统模型。为了解决多个用户同时卸载带来的严重通信干扰等问题，以高效利用边缘服务器资源，提出了一种联合任务卸载和资源分配的优化方案，在满足用户服务质量的前提下最小化系统总能耗。该方案联合考虑了卸载决策、功率控制、计算资源和子信道资源分配。仿真结果表明，与其他卸载方案相比，所提方案可以在满足用户服务质量的前提下有效降低系统能耗。

Abstract

In order to improve spectrum efficiency and meet the service demands of massive users

a non-orthogonal multiple access (NOMA)-based ultra-dense mobile edge computing (MEC) system was considered.In order to solve the serious communication interference caused by simultaneous offloading of multiple users and make efficient use of edge server resources

a joint task offloading and resource allocation scheme was proposed to minimize the system energy consumption while meeting the quality of service (QoS) of all users.Offloading decision

power control

computation resource and subchannel resource allocation were jointly considered in the proposed scheme.Simulations results show that the proposed scheme can efficiently lower system energy consumption compared to the other offloading schemes.
