SCHOOL: Spectrum Allocation for D2D Communication Enabled HetNet using Stackelberg and Coalition Formation Game

The number of wireless network devices has grown exponentially over the few last decades. Properly allocating the right spectrum of these large number of devices is one of the biggest challenges for future networks. In this article, we have described the method of spectrum allocation based on Stackelberg game and coalition formation game. The Stackelberg game is used to assign the spectrum to devices connected with small cell base station (SBS), and the coalition formation game is used to allocate the spectrum between device-to-device (D2D) communication devices. Two utility functions have been proposed and through these functions the network operator assigns the required spectrum to the devices. In SCHOOL, we have calculated the signal to interference plus noise ratio (SINR) and spectral efficiency (SE) of the network and compared it with the previous networks. The proposed SCHOOL has generated similar to 2% - 8% more SINR than existing network.
