Mobile Multimedia applications have experienced an explosive growth nowadays. People are more excited to receive high speed videos in addition to audio,voice and web services even when they are on move. However, multimedia applications require certain Quality of Service (QoS) support such as guaranteed bandwidth,delay and jitter. Although IEEE 802. 11 Wireless LAN (WLAN) is most widely used WLAN standard today, it cannot provide QoS support for increasing number of multimedia applications. Thus, 802. 11e provides QoS to multimedia applications. In this paper, a Priority Technique based on EET (Earliest Expiry Time) in SWEET(Sorter With Earliest Expiry Time) module is proposed in IEEE 802. 11 for rescheduling and servicing of video packets with desired QoS. The simulation results produced a better performance when compared with existing one.
