A cross-layer performance analysis of a wireless network using adaptive modulation and coding at the physical layer and a truncated Chase combining hybrid automatic repeat request (HARQ-CC) scheme for error control at the data link layer is developed. Based on a Markov chain queueing model, analytical expressions for performance metrics such as throughput, average packet delay and packet loss rate...
A Markov chain-based queueing model is developed for a cross-layer performance analysis of a wireless network based on adaptive modulation and coding (AMC) at the physical layer and truncated automatic repeat request (ARQ) error control at the data link layer. This model generalizes previous results by using a first-order two-dimensional Markov chain to model the wireless fading channel. Furthermore,...
In this paper, a novel framework for the cross-layer design of wireless networks combining adaptive modulation and coding (AMC) at the physical layer with an automatic repeat request (ARQ) protocol at the data-link layer is proposed. In order to achieve this goal, the physical-layer service process is first modeled as a multidimensional finite-state Markov chain. Then, based on this multidimensional...
This paper proposes a novel framework for the cross-layer analysis and design of wireless networks combining adaptive modulation and coding (AMC) at the physical layer with an automatic repeat request (ARQ) protocol at the data-link layer. Most previous works rely on first-order amplitude-based finite-state Markov chains (AFSMCs) to model the physical layer. It is shown that these models present several...
Nowadays, there are lots of research efforts focusing on cross-layer designs combining adaptive modulation and coding (AMC) with an automatic repeat request (ARQ) protocol. One of the main drawbacks of these research works is that they rely on first-order amplitude-based finite-state Markov chains (AFSMC) to model the wireless fading channel. Furthermore, most of the analytical models used in these...
