Abstract :
In this paper, a queue aware game theoretic cross-layer scheme is introduced for multiuser orthogonal frequency division multiple access (OFDMA) wireless systems. A joint scheduling process that combines an adaptive modulation (AM) at the physical layer (PHYL) along with a discrete Markov modulated Poisson process (dMMPP) at the medium access control (MAC) layer, is devised. Moreover, relied on this cooperative game theoretic architecture, we formulate an optimization problem on a Nash bargaining solution (NBS) basis. Finally, the allocation policies result an optimal tradeoff between proportional fairness and throughput maximization that fits in realistic wireless networks scenarios.
