MAC Scheduling Schemes and Cross Layer Optimization for IEEE 802.15.3
In this paper, the performances of variety of HDR MAC scheduling schemes over IEEE 802.15.3 WPAN are examined. The scheduling schemes under investigation are 1) the shortest remaining processing time rule (SRPT); 2) the exponential rule (EXP); 3) the modified largest weighted delay first rule (M-LWDF); 4) the proportionally fair rule (PROP-FAIR); and 5) the maximum rate rule (MAX-RATE), most of which take advantage of wireless channel conditions to improve channel utilization. In addition, M-LWDF rule and EXP rule provide QoS guarantee to user traffic as well. The performances were studied under large number of simulation using ns-2, which take node mobility, channel fading and traffic characteristics into consideration in order to make the results more realistic. We also studied the performances gain of scheduling schemes combined with some cross layer mechanisms, including frame-decodability aware (FDA) mechanism for MPEG traffic, adaptive MAC fragment size adjustment and hybrid automatic repeat request (H-ARQ).
