Abstract: This paper presents a different MAC Protocol which is specially designed for narrow-bandwidth WLAN. Simulation result and numerical analysis are presented to demonstrate the effectiveness of dual_stage busytone backoff (DBBO). The simulation result also proves that the correctness of the numerical analysis.

Key words: dual_stage busytone backoff(DBBO), IEEE 802.11 DCF, narrow-bandwidth WLAN
