Research on resource allocation algorithm in D2D networks based on alliance game

Abstract： The rapid increase in the number of users in wireless networks has brought huge challenges to the existing network architecture, and how to increase the system capacity effectively is an urgent problem to be solved. Due to the superior performance in improving spectrum efficiency and increasing system capacity, Device-to-Device(D2D) communication and sparse code multiple access(SCMA) as the key technics in the development of 5G in the future have been extensively studied. Aiming at the communication resource allocation problem in the SCMA system in the single-cell scenario, this paper aims to maximize the system throughput and ensure the minimum threshold rate of all users, and model it as an alliance game to solve it. Due to the problems of high complexity and slow convergence in traditional alliance game algorithms, this paper proposes to establish a priority sequence to guide the initialization and formation process of alliances, thereby reducing the number of algorithm iterations and reducing system complexity. Finally, the feasibility of the algorithm is verified by simulation.
