Traffic measurements from communication networks have shown that network traffic is exhibiting self similar as well as long range dependence properties. In telecommunication networks, congestion events tend to persist, producing large delays and packet loss resulting in performance degradation. In order to guarantee quality of service to diverse Internet services, congestion prediction became a fundamental...
To support the differentiated Quality-of-Service (QoS) and improve the utilization of the scarce wireless bandwidth, the IEEE 802.11e standard specifies an efficient burst transmission scheme referred to as the transmission opportunity (TXOP). Recently, analytical models have been reported to evaluate the performance of the TXOP scheme. However, most of these models were developed under the assumptions...
The enhanced distributed channel access (EDCA) protocol has been proposed to support differentiated quality-of-service (QoS) of wireless local area networks (WLANs). edca introduces a promising scheme, transmission opportunity (TXOP), which enables a station to transmit multiple frames consecutively in a burst upon winning the contention of the channel. The analytical models of the TXOP scheme have...
The main goals of quality-of-service (QoS) routing algorithms are: (1) to try to accommodate new connections which expect certain end-to-end QoS requirements and (2) to improve the overall network efficiency. These QoS requirements are in the form of delay, jitter, packet-loss and bandwidth. In order to accommodate every new connection through the network that satisfies the QoS, the resources must...
Arbitrary inter-frame space (AIFS), contention window (CW) and transmission opportunity (TXOP) are three important quality-of-service (QoS) differentiation schemes specified in the IEEE 802.11e enhanced distributed channel access (EDCA) protocol for wireless local area networks (WLANs). Analytical models of EDCA in the current literature have been mainly developed for the AIFS, CW, and TXOP schemes,...
