Performance Evaluation and Enhancement of the CSMA / CA MAC Protocol for 802 . 11 Wireless LANs �


ABSTRACT. The IEEE 802.11 protocol for Wireless Local Area Networks adopts a CSMA/CA protocol with exponential backoff as medium access control technique. As the throughput performance of such a scheme becomes critical when the number of mobile stations increases, in this paper we propose an Adaptive Contention Window mechanism, which dynamically selects… (More)
