Selfish MAC Layer Misbehavior In Wireless Networks
White Papers For example, IEEE 802.11 requires hosts competing for access to the channel to wait for a "Backoff" interval, randomly selected from a specified range, before initiating a transmission. Selfish hosts may wait for smaller backoff intervals than well...

Performance Modeling And Evaluation Of IEEE 802.11 Distributed Coordination Function In Multihop Wireless Networks
White Papers DCF is a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) scheme combined with Binary Exponential Backoff (BEB). Initially designed for WLAN's, IEEE 802.11 Medium Access Control (MAC) has also been widely used in the research of...

Enhanced Backoff Scheme In CSMA/CA For IEEE 802.11
White Papers In both cases, a binary exponential backoff mechanism is used. The enhanced protocol improves the exponential backoff scheme by dynamically adjusting the Contention Window (CW) around the optimal value.

Throughput Enhancement Of IEEE 802.11 WLAN Via Frame Aggregation
White Papers This is due mainly to the large overheads composed of Medium Access Control (MAC) header, PHY preamble/header, backoff time, ACKnowledgement (ACK) transmission, and some Inter-Frame Spaces (IFSs). The popular IEEE 802.11 WLAN is known to achieve...
