Cooperative Slice Allocation for Virtualized Wireless Network

Wireless networks for next generation (5G) are envisioned to accommodate massive data with support to various novel services. One promising solution to accommodate this tsunami of data and novel services is Wireless network virtualization (WNV). Through WNV, the infrastructure providers enables resource sharing to mobile virtual network operators in a transparent manner. Moreover, each mobile virtual network operators possesses a virtual resource called slice based on its user's requirements. Thus, infrastructure provider needs to consider efficient allocation of these slices for each MVNOs. In this work, we consider a practical multiple infrastructure provider scenario and formulate a slice allocation problem. To solve this problem, we present an efficient slice allocation scheme based on the matching game theory framework. Specifically, we define how to allocate the sliced resource efficiently among MVNOs users with different service requests. Simulation results illustrate the effectiveness of our proposal in terms of average sum-rate, admitted users and convergence.
