algorithm, named Adaptive Credit-Based Fair Queuing (ACFQ) Based on Credit-Based
Fair Queuing (CBFQ) is introduced. The proposed algorithm adapts the error-free
CBFQ with the multi-rate nonideal environment considering the Adaptive
Modulation and Coding (AMC) at the radio link layer and provides packet-level
Quality of Service (QoS) over the wireless fading channel. It is shown
that the introduced AMC architecture and compensation model in two-layer
scheduling provide fair sharing while ensuring high bandwidth efficiency.
Furthermore, the proposed scheduler exhibits very low complexity, thus
suitable for practical implementation.]]>Bennett, J.C.R. and H. Zhang,1996Bensaou, B., H.K. Tsang and K.T. Chan,2001Chen, J., W. Jiao and H. Wang,2005Cicconetti, C., L. Lenzini, E. Mingozzi and C.
