2018 년 한국컴퓨터종합학술대회 논문집 Resource Allocation for Virtualized Wireless Network with Mobile Edge Computing and Spectrum Sharing

In this paper, we propose a virtualized wireless network architecture, where the resources of a set of Mobile Edge Computing (MEC) servers and unlicensed spectrum-based radio resources are virtualized from a mobile virtual network provider (MVNO) to provide an offloading-service to subscriber users. To reap the full benefits of the MVNO, an optimization problem is formulated, the aim is to minimize the total delay of the tasks while protecting the macrocell base station. The problem is become a combinatorial optimization problem, which is an NP-hard. A matching theory frame with a low-complexity solution is used to solve the above optimization problem. Simulation results show the benefit of the network architecture and formulated frame work.
