Abstract : In this paper we propose a useful framework for a cross layer design and analysis of wirelessnetworks where an AMC (Adaptive Modulation and Coding) scheme is employed. In the framework,we model the joint effect of the packet transmission error rate at the PHY layer and thepacket loss probability at the MAC layer by introducing the effective bandwidth function of thepacket service process. With the help of the effective bandwidth function, we can characterizethe wireless channel, analyze the queueing system, and determine an AMC scheme whichsatisfies the required packet loss probability by a user and minimizes the average packet transmissionerror rate. Some numerical examples show the characteristics of wireless networks withan AMC scheme and how to determine an AMC scheme in detail.
