Auction Mechanism-Based Sectored Fractional Frequency Reuse for Irregular Geometry Multicellular Networks

Modern cellular systems have adopted dense frequency reuse to address the growing amount of mobile data traffic. The system capacity is improved accordingly; however, this at cost augmented Inter-Cell Interference (ICI). Recently, Fractional Frequency Reuse (FFR) has emerged as an efficient ICI management scheme in Orthogonal Frequency-Division Multiple Access (OFDMA)-based systems. However, FFR that leads optimized spectrum allocation for individual users irregular geometry networks not considered literature. Meanwhile, practical wireless scenario, are non-cooperative and want maximize their demands. A game-theoretic Auction Mechanism-based Sectored-FFR (AMS-FFR) proposed paper optimally distribute bandwidth resources realistic multicellular network deployment. In auction mechanism, Base Station (BS) acts auctioneer owner sub-carriers. permitted bid a bundle sub-carriers corresponding traffic requirements. Monte Carlo simulation results show presented AMS-FFR outperforms prevailing schemes terms achievable throughput by 65% 46% compared basic FFFR dynamic FFR-3 schemes, respectively. Moreover, average sum rate along with user satisfaction significantly increased while considering full load.
