Abstract

In this paper, we investigate packet scheduling and radio resource allocation in orthogonal frequency division multiple access (OFDMA) wireless networks. Each subchannel is a Rayleigh fading channel modeled by a finite state Markov channel (FSMC). The wireless fair service (WFS) packet scheduler is modified for a multi carrier and multi rate context. The proposed algorithm, named opportunist wireless fair service (OWFS), copes with both real time (RT) and non real time (NRT) traffic constraints. For both traffic classes, specific criteria of performance are compared with PLFS, a scheduler recently proposed for OFDMA.
