A dynamic link adaptation algorithm for IEEE 802.11 a wireless LANs
IEEE International Conference on Communications, 2003. ICC'03., 2003•ieeexplore.ieee.org
We present a simple but powerful dynamic link adaptation mechanism for wireless LANs,
which are based on the IEEE 802.11 a standard. Using this method, a transmitter is able to
detect whether the quality of the link is improving or deteriorating, and based on this
information to switch to a higher or lower transmission rate, respectively. For determining the
link quality, the transmitter employs only information that is available locally. Therefore, the
proposed method can be implemented without changes or enhancements to the current …

The efficiency of our method is investigated and evaluated by means of simulations.
