Abstract
A system and method for dynamic rate adaptation in wireless networks is presented. A dynamic adjustment scheme adapts quickly to channel variation characteristics where adjustment values depend on the target data packet completion rates that maximizes the effective throughput. The required information is an estimate of the Medium Access Controller overhead including channel access delay. This a priori information can also be measured by the system a posteriori. Although the invention can be applied to both cellular and non-cellular systems, the exemplary embodiment is given for a carrier sense multiple access with collision avoidance (CSMA/CA) network.
