Abstract

To ensure gains from the ultra-dense networks (UDNs) with multi-slope channels, we cluster small base stations (SBSs) with intra-cluster orthogonal bands and inter-cluster shared bands, and establish some new stipulations tailored for UDN deployment. Under such proposed interference management strategies and proportional remote computation allocation, we jointly optimize computation offloading and power control to minimize local energy consumption. The problem is decomposed into: (1) an offloading subproblem solved via an improved coalitional game-based algorithm, and (2) a power control subproblem transformed into single-variable polynomial optimization, solved via a two-tier iterative algorithm using Newton-like and fixed-point iteration approaches. Simulations demonstrate that the designed algorithm, integrating proposed interference management strategies and proportional remote computation allocation, outperforms existing methods in minimizing local energy consumption under strict latency requirements.

多坡通道集群mec超密集网络的联合计算卸载与资源分配

为了保证多坡信道的超密集网络（UDN）的增益，我们将小型基站（SBSs）聚集在集群内的正交频段和集群间的共享频段上，并建立了一些针对UDN部署的新规定。在此干扰管理策略和远程计算比例分配下，共同优化计算卸载和功率控制，使局部能耗最小化。将该问题分解为：(1)采用改进的联合博弈算法求解卸载子问题；(2)将功率控制子问题转化为单变量多项式优化，采用类牛顿和不动点迭代两层迭代算法求解。仿真结果表明，该算法集成了所提出的干扰管理策略和比例远程计算分配，在严格的延迟要求下，在最小化局部能耗方面优于现有算法。
