Spectrally efficient resource allocation for device to device communication underlying cellular network: Sum rate priority iterative auction based approach

Device to Device communication has been considered as a popular issue for small cell networks. In this paper, a Sum Rate Priority Iterative Auction scheme is proposed to improve the spectral efficiency of mobile peer-to-peer communication for downlink cellular network. For spectral efficiency, first allocation of spectrum to various cellular and d2d devices is done by Reverse-iterative combinatorial auction mechanism, in which the cellular devices laced with spectral bandwidth bid for d2d devices iteratively. Optimization of spectrum is done by plotting sum-rate over SINR, number of cellular devices and number of d2d users. In addition, we compare the results obtained in Reverse Iterative combinatorial Auction (R-ICA) method with Sum Rate Priority Iterative Auction method by plotting the obtained spectral efficiency against the number of D2D users.
