New-MAC protocol for enhancement of QoS performance in wireless LAN

The wireless local area network (WLAN) is becoming popular due to its inherent strength. However, there are major challenges to be over come in WLAN. Some of them are quality of service (QoS), seamless mobility and security. Extensive research is being carried out to address QoS in WLAN. In this paper we propose a new medium access control (MAC) protocol for QoS (New-MACQoS) in WLAN. It has been observed that, the average delay performance by this New-MACQoS for different services (voice, video, best-effort data) is better than the extended distributed coordination function (LDCF) used in IEEE 802.11e and adaptive EDCF (AEDCF) in Qiang Ni, (2005) for QoS of WLAN.
