Resource Allocation for Device-to-Device Communication in LTE-A Network: A Stackelberg Game Approach

As a promising technology, Device-to-Device (D2D) communication can bring some advantages such as high bit rates, low delays, low power consumption by reusing frequency band with the cellular user equipments (UEs). While at the same time, inter-cell and intra-cell interference is inevitable. In this paper, we propose an algorithm Stackelberg game based to jointly allocate power and resources when uplink frequency is shared. Specially, we group evolved NodeB (eNB) and D2D UE to form the seller- buyer pair. In the game, eNB sets prices to reduce the interference that it suffers from, meanwhile maximize its revenue. For given specified prices, the D2D users compete the resources to communicate with each other and reach their individual utility maximization. Simulation results prove that satisfying performance can be achieved by using the proposed mechanisms.
