Implicit Block ACK Scheme for IEEE 802.11 WLANs
The throughput of IEEE 802.11 standard is significantly bounded by the associated Medium Access Control (MAC) overhead. Because of the overhead, an upper limit exists for throughput, which is bounded, including situations where data rates are extremely high. Therefore, an overhead reduction is necessary to achieve higher throughput. The IEEE 802.11e amendment introduced the block ACK mechanism,...
متن کاملCooperative MAC Protocol based on TXOP and Block ACK in IEEE 802.11e WLANs
The IEEE 802.11 MAC protocol cannot support quality of service (QoS) requirements. In order to provide QoS in the IEEE 802.11 MAC protocol, the IEEE 802.11e has been standardized. These standards provide multiple transmission rates, which can be changed dynamically according to the channel condition. When using multiple transmission rates, the capacity of wireless LAN improves, but the performa...
متن کاملA performance analysis of block ACK scheme for IEEE 802.11e networks
The demand for the IEEE 802.11 wireless local-area networks (WLANs) has been drastically increasing along with many emerging applications and services over WLAN. However, the IEEE 802.11 medium access control (MAC) is known to be limited in terms of its throughput performance due to the high MAC overhead, such as interframe spaces (IFS) or per-frame based acknowledgement (ACK) frame transmissio...
متن کاملFastScan: a handoff scheme for voice over IEEE 802.11 WLANs
IEEE 802.11 Wireless LANs are increasingly being used in enterprise environments for broadband access. Such large scale IEEE 802.11 WLAN deployments implies the need for client mobility support; a mobile station has to be “handed off” from one Access Point to another. Seamless handoff is possible for data traffic, which is not affected much by the handoff delay. However, voice traffic has strin...
متن کاملAn Adaptive Multimedia-Oriented Handoff Scheme for IEEE 802.11 WLANs
Previous studies have shown that the actual handoff schemes employed in the IEEE 802.11 Wireless LANs (WLANs) do not meet the strict delay constraints placed by many multimedia applications like Voice over IP. Both the active and the passive supported scan modes in the standard handoff procedure have important delay that affects the Quality of Service (QoS) required by the real-time communicati...
