In this paper, a novel analytic framework of cross-layer design between physical and network layers is devised to enable an efficient communication link under various channel qualities. Based on the principle of Maximum Entropy (ME), the performance modelling and evaluation of a wireless channel with bursty multiple traffics and Automatic Repeat reQuest (ARQ) traffic flows subject to Intelligent Buffer Management Scheme (IBMS) is investigated. As the packet error rate varies depending on channel quality, better performance of IBMS can be achieved under Adaptive Modulation (AM).
