"This paper describes a mathematical model of the Enhanced Distributed Coordination Function (EDCF), a novel media access mechanism used in the IEEE 802.11 technology. For this purpose, Markov Chains are employed. Based on this model, a mathematical expression of the normalized saturation throughput is derived. Furthermore, series of simulation results are shown that are focused on the dependency of the throughput and media access delay on the load for diverse EDCF parameters. Finally, the influence of the minimal and maximal contention window on the throughput and media access delay is analyzed."@en . . . "978-80-248-2399-7" . "2011-06-22+02:00"^^ .
