Abstract(in English) | Using the analysis model of IEEE 802.11 DCF with mean field approximation, we show that the wireless LAN (WLAN) based on the IEEE 802.11 DCF has two stable equilibrium states when the offered load is approximately equal to the capacity of the WLAN. The existence of the bistable state is closely related to the queue of frames waiting for transmission within a terminal. A terminal in one of the two stable states has few frames and the one in the other stable state has a long queue of frames waiting for transmission. The existence of the bistable state becomes more prominent as the number of terminals increases. The existence of the bistable state predicted by the analytical model is also confirmed in the simulation. |
