Channel Access in D2D Multiuser Networks: A Game Theoretical Approach

In this paper we consider allocation of the uplink resource of a cellular user to a group of Device-to-Device (D2D) links communicating in pairs to enhance the overall system throughput and achieve higher spectral efficiency in multiuser networks. We present a coalition game model for coalition formation decisions which ensures that interference does not exceed an acceptable limit and guarantee an optimal rate for each user in the cellular network.We propose an algorithm which detect sufficient condition needed for stability in the coalitions formed. We present simulation results to test the validity of our algorithm.
