Description: To support the varying Quality-of-Service (QoS) requirements of emerging applications such as those involving continuous media, a new standard IEEE 802.11e has been specified [1]. This standard aims to support QoS by providing differentiated classes of service at the medium access control (MAC) layer to enhance the ability of physical layers to deliver time-critical traffic in the presence of traditional data packets. The 802.11e standard defines four access categories (ACs). These four ACs have different transmission priorities. The transmission priority is the probability of successfully earning the chance to transmit when individual ACs are competing to access the wireless channel the higher the transmission priority, the better is the opportunity to transmit.-To support the varying Quality-of-Service (QoS) requirements of emerging applications such as those involving continuous media, a new standard IEEE 802.11e has been specified [1].

Description: Despite its support of prioritized services, the IEEE
802.11e Enhanced Distributed Channel Access (EDCA)
cannot guarantee strict QoS required by real-time services
such as voice and video without proper network control
mechanisms. To overcome this deficiency, we first build
an analytical model to derive upper bounds for both delay
means and variations for services of different priorities in
the non-saturated 802.11e WLAN, showing that the QoS requirements
of real-time services can be satisfied if the input
traffic is properly regulated. Platform: |
