Summary
With ever increasing popularity of multimedia applications, people want voice, audio and broadband video services like High De nition TV (HDTV) through WLAN connections. Unlike the traditional best eff ort data applications, multimedia applications require Quality of Service (QoS) support such as guaranteed bandwidth and bounded delay/jitter.
The original 802.11 standard does not take QoS into account. Hence to provide QoS support IEEE 802.11 standard group has speci ed a new IEEE 802.11e standard. IEEE 802.11e supports QoS with two channel access mechanism: HCCA and EDCA.
In this dissertation we present a schedu ler that allows QSTA to use both access function for the same flow.
