In a typical installation of an 802.11 based WLAN (Wireless Local Area Network), mobile hosts would access the network through APs (Access Points), even when two mobile stations communicate within the same WLAN. Effectively, all the packets in a WLAN are required to forward through the AP according to the MAC (Medium Access Control) layer protocol. Since the AP has the same priority as the other mobile stations to access the channel, the AP usually becomes a bottleneck in WLANs and the network performance degrades significantly. In this paper, we propose a new MAC layer protocol for WLANs in order to improve the through-put performance. Theoretical analysis and simulation results show that our new protocol works much better in WLAN than the standard DCF.
