Resource Allocation and Computing Offloading in Ultra-dense Networks Based on NOMA
Aiming at the problem of limited communication resources and difficulty in guaranteeing task completion time for computing offloading in mobile edge computing(MEC).In this paper,in order to improve spectrum efficiency,it applies non-or-thogonal multiple access technology(NOMA)to ultra-dense networks,and proposes a joint computing offloading and resource allo-cation scheme to maximize system offloading revenue.First,the matching alliance method and the dichotomy are used to solve the resource allocation problem.Then,based on the results of resource allocation,a computational offloading decision algorithm is pro-posed to obtain the optimal task offloading plan.Compared with other solutions,the solution proposed in this paper can significantly increase the offloading revenue of the system.
