چكيده فارسي :
A multichannel scheduling based on an
extension of modified largest weighted delay first (MLWDF)
scheduling is proposed for heterogeneous
traffic. We consider the downlink of an orthogonal
frequency division multiplexing (OFDM) system where
the wireless channel and queue state information are
taken into account to schedule delay-sensitive and ratesensitive
traffic. We propose a logarithmic notion of MLWDF
scheme, denoted LOG-M-LWDF, and we prove
its stability analytically. The simulation results show
that the proposed scheduling scheme outperforms MLWDF
in terms of service delay performance.
