“…Bypassing the mutual dependence of other layers yields suboptimal results in CL optimization, e.g., ignoring a queuing scheme at the data link layer may cause delay, a crucial metric in multimedia streaming. The effect of delay on multimedia traffic has been studied in multiuser SDMA/TDMA system [22]. However, the missing parameters at the application layer make the proposed CL design less performing, and this design has only been investigated by simulations.…”

“…In general, packets are stored in a buffer at the data link layer before being forwarded to the destination, which may cause a delay in delivering packets. For a multiuser spacedivision multiple access (SDMA)/time-division multiple access (TDMA) system, the effect of a queuing delay on CL design with multimedia traffic has been reported in [22]. However, this CL design, which combines the PHY layer with opportunistic scheduling taking into consideration of the queuing effect, has only been verified by simulations.…”

Abstract-To cope with the rapid growth of multimedia applications that requires dynamic levels of quality of service (QoS), cross-layer (CL) design, where multiple protocol layers are jointly combined, has been considered to provide diverse QoS provisions for mobile multimedia networks. However, there is a lack of a general mathematical framework to model such CL scheme in wireless networks with different types of multimedia classes. In this paper, to overcome this shortcoming, we therefore propose a novel CL design for integrated real-time/non-real-time traffic with strict preemptive priority via a finite-state Markov chain. The main strategy of the CL scheme is to design a Markov model by explicitly including adaptive modulation and coding at the physical layer, queuing at the data link layer, and the bursty nature of multimedia traffic classes at the application layer. Utilizing this Markov model, several important performance metrics in terms of packet loss rate, delay, and throughput are examined. In addition, our proposed framework is exploited in various multimedia applications, for example, the end-to-end real-time video streaming and CL optimization, which require the priority-based QoS adaptation for different applications. More importantly, the CL framework reveals important guidelines as to optimize the network performance.Index Terms-Cross-layer (CL) optimization, delay, multimedia applications, quality of service (QoS), throughput.
