摘要：
Accurately modeling the IEEE 802.11 DCF is critical to analyze the performance of wireless LAN. However, current models cannot express network performance correctly in the case of multi-rate due to its normalized throughput definition. Therefore, a new Markov model with absorbing state is proposed based on the comprehensive analyses and researches, and the system throughput is redefined. Simulation results show that the proposed model can exhibits the throughput performance of network system, and provides more precise modeling when considering multi-rate situations.
