  7. Abstract:
  8. In the next generation of wireless networks, wireless network virtualization is considered as an efficient technology to enhance the network capacity. This technology enables the separation between wireless network infrastructure and the services it provides that enhances some of the existing capabilities and make new capabilities in the network. Spectrum sharing,infrastructure sharing, network sharing, resource slicing are some of these capabilities.Furthermore, the mentioned separation causes the lower entry barriers for small beneficiary entities. The increment in the number of beneficiary entities makes intense competitions among them leading to lower costs for different services. Also, improvement in the network capacity leads to lower number of new required base stations which leads to non-incremental capital and operational expenditures.In this thesis, using the three-level business model of wireless network virtualization contained of infrastructure providers (InPs), mobile virtual network operators (MVNOs) and service providers (SPs), we propose a structure that models interactions between an SP and a group of MVNOs. The SP supports a group of subscribed users. Each subscriber requires a specific data rate. Therefore, the SP makes contracts with different MVNOs for provisioning virtual resources for its subscribers. The SP, using the VCG mechanism for the porocurement auction, assigns its subscribers to different MVNOs. According to this mechanism, each MVNO declares its bid for each subset of subscribers to the SP, and the SP through maximizing its profit assigns subsceribers to MVNOs. Also, we utilize theVDA algorithm for achieving the outcome of the VCG mechanism with less computational complexity. Our simulation results show the superiority of our resource provisioning approach compared with some other approach
