In this paper, first, energy efficiency of well known and principal scheduling schemes, Round Robin (RR), Best Channel Quality Indicator (BCQI), and Proportional Fair (PF) is evaluated. Then, a novel energy efficient scheme in low load traffic conditions is proposed. The proposed scheme trades off bandwidth for energy whenever possible depending on the load of the network. By applying this approach...
Fair weights have been implemented to maintain fairness in recent resource allocation schemes. However, designing fair weights for multiservice wireless networks is not trivial because users' rate requirements are heterogeneous and their channel gains are variable. In this paper, we design fair weights for opportunistic scheduling of heterogeneous traffic in orthogonal frequency division multiple...
