Abstract
The contention-based DCF of IEEE 802.11 adopts the 4-way handshaking mechanism for reasonable transmission with reduced packet collisions. But, expected CTS is not successfully received by the transmitter, the NAV of the transmitter’s neighbors leads to two problems: degrading channel utilization and unbalancing of fairness. We propose BN-MAC to improve the performance of WLAN using BNACK packet to reset NAV to zero. The neighbors that receive BNACK defer only SIFS for fairness of overall network. The performance of our approach is compared with the IEEE 802.11 DCF and optional DCF by simulation. The results show that our proposed approach reduces end to end delay and improves the channel utilization.
