Auction based algorithm for distributed resource allocation in multitier-heterogeneous cellular networks

Due to the multi-tier heterogeneous nature of the 5G cellular networks, where the small cells and the D2D pairs are underlaied in the macrocell, Centralized methods for resource allocation will be very complex. In this paper a distributed algorithm using auction technique is adopted to maximize the datarate of the underlay layer users, while maintaining the interference in the macro tier within the acceptable range. The convergence of the algorithm, and other parameters is investigated, also the effectiveness of the solution compared to the central solution is studied.
