Abstract: In view of the characteristics of traditional wireless access network decoupling and virtualizing in M-CORD architecture, the dynamic radio resource allocation and optimization are studied with the supporting of the centralized control and global monitoring of SDN（Software Defined Network）. The computing resources of the datacenter are considered as one of the factors affecting resource allocation. Taking the interference threshold, front-haul capacity constraints, user mobility, minimum resource rate guarantee and computing resource constraints into account, the resource allocation formula of the wireless access network under the M-CORD architecture is deduced. And the suboptimal solution of resource allocation is found by improving the increment-based greedy allocation algorithm. Through simulations and evaluations, it is proved that the improved algorithm can effectively realize the wireless access network resource allocation in M-CORD architecture.
