“…To this end, according to [3], the entire SNR range is partitioned into a set of non-over lapping intervals defined by the partition to determine TMn. In this paper, the partition is obtained by using the threshold searching algorithm described in [10]. This searching algorithm has the capability to discriminate between useful and useless TMs and at the same time to guaranty the required average PER.…”

“…Literature review indicates that much work has focused on cross-layer designs by combining the AMC schemes with HARQ or ARQ error control protocols [9][10][11] while limited researches have addressed the multiuser scheduling at the MAC sub-layer [12÷15]. In [15] the authors presented an opportunistic scheduling scheme to improve the delay performance of secondary users with bursty traffic in cognitive radio (CR) systems.…”

Original scientific paper This paper proposes a novel framework for the cross-layer design and optimization of wireless networks combining adaptive modulation and coding (AMC) at the physical (PHY) layer by means of automatic repeat request and channel-aware multiuser scheduling protocols at the data link control (DLC) layer. The proposed framework is based on the use of two-dimensional discrete time Markov chains (DTMCs) jointly modelling the AMC scheme and the amplitude contention window (CW). A new algorithm for dynamic configuration of the polled transmission opportunity (TXOP) in multi-rate IEEE 802.11e network is presented and its performance is analysed and compared with default configuration. The numerical simulation results have indicated the high efficacy of the proposed method in maximizing the average throughput of the system.

“…Consequently, cross-layer designs able to jointly optimize the scheduling, ARQ, and AMC functions should be devised. Although many recent works focus on cross-layer designs that combine AMC schemes with ARQ error control protocols (see, e.g., [1][2][3][4][5][6][7][8][9][10][11][12]), proposals also incorporating the multiuser scheduling process at the media access control (MAC) sublayer are much less common (see, e.g., [13][14][15]). Liu et al in [15] presented an opportunistic scheduling scheme to improve the delay performance of secondary users with bursty traffic in cognitive radio (CR) systems.…”

“…The max-rate multiuser scheduler was included in the model through a service-vacation process allowing a manageable number of system states irrespective of the number of users sharing the channel. Nevertheless, the analysis in [14] suffers from an inaccurate modeling of the flat-fading wireless channel caused by the use of a first-order AFSMC (see [9][10][11][12] for an indepth discussion of this and related issues). Moreover, the approach in [14] does not define a cross-layering scheme as a means to optimize the system performance, and on top of this, users are assumed to operate in channels with equal characteristics, thus restricting the usefulness of the presented results.…”

“…In this paper, capitalizing on the approach described in [14], a service-vacation process is used to embed the channel-aware scheduling protocol behavior into the AMC/ARQ multidimensional discrete time Markov chain (DTMC) model described in some of our previous contributions [9][10][11][12]. Our approach is based on a first-order two-dimensional (2D) Markov model for the wireless flatfading channel that, as was shown in [9][10][11][12], solves most of the drawbacks of the AFSMC model used in [1][2][3][4][5][6][7][8]13,14].…”

This paper proposes a novel framework for the cross-layer design and optimization of wireless networks combining adaptive modulation and coding (AMC) at the physical (PHY) layer with automatic repeat request and channel-aware multiuser scheduling protocols at the data link control (DLC) layer. The proposed framework is based on the use of first-order two-dimensional discrete time Markov chains (DTMCs) jointly modeling the AMC scheme and the amplitude and rate of change of the wireless channel fading envelope. The behavior of the scheduler is embedded into the multidimensional PHY layer Markov model through the use of a service-vacation process. Using this PHY-media access control (MAC) Markov model, the quality of service performance at the DLC layer is discussed considering two different approaches. The first one relies on an analytical framework that is based on the multidimensional DTMC jointly describing the statistical behavior of the arrival process, the queuing system, and the PHY layer. The second one is rooted in the use of the effective bandwidth theory to model the packet arrival process and the effective capacity theory to model the PHY/MAC behavior. Both the DTMC-based and effective bandwidth/capacity-based approaches are analyzed and compared in a cross-layer design aiming at maximizing the average throughput of the system where constraints on the maximum tolerable average packet loss and delay are to be fulfilled.

In this paper, we analyze the performance of adaptive modulation-based Bell-labs layered space-time systems with finite-length queuing model. Since the thresholds values for the adaptive modulation scheme should be optimized when the queuing model is taken into account in the system, cross-layer performance analysis on the queuing behavior is necessary. The most important contribution of our work is to express the service rate distribution of adaptive modulation-based BLAST system in closed form. Moreover, from discrete Markov chain analysis, we obtain the performance of the queuing model such as overall packet error rate and average queuing delay. Then, we discuss three applications of the accurate numerical results in cross-layer designs. The accuracy of the numerical results is verified by Monte Carlo simulations.
