Distributed Resource Allocation for D2D Communication Networks using Auction

Fifth generation (5G) cellular networks expected to overcome the limitations of existing networks and provide high data rates, better user performance, low latency, low power consumption and low cost. To handle these requirements, 5G will use heterogeneous multi-tier networks consisting of small cells, relays, and device to device (D2D) communication. However, using this network architecture and new techniques raise new challenges such as implementing efficient resource allocation of this multi-tier networks. In this paper, the effect of using relay assisted D2D communication as undelay tier of cellular users. The resource allocation problem is formulated to maximize the system data rate while considering the co-channel interference resulted from the D2D underlay tier which share the same resources with the cellular users. Auction based algorithm is used to solve the proposed allocation problem in distributed manner with very low complexity compared to the centralized methods.
