摘要: The aim of this paper is threefold. First, it presents a multi-dimensional Markovian state transition model characterizing the behavior IEEE 802.11 protocol at Medium Access Control layer which accounts for packet transmission failures due to channel errors modeling both saturated and nonsaturated traffic conditions. Second, provides throughput analysis data link in non-saturated conditions taking into account impact physical propagation multirate Rayleigh fading environment. general assumed M/M/1/K. Finally, shows that linear combination two system parameters; payload size rates, λ, each contending station. validity interval proposed also derived. Simulation results closely match theoretical derivations, confirming effectiveness models.
