Abstract

A system and method for dynamic rate adaptation in wireless networks is presented (Fig. 4). 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 posteriors. 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.

completion rate is higher than the target packet completion rate, and wherein said adjusting the data rale threshold values comprises decreasing the selected data rate when the actual packet completion rate is lower than the target packet completion rale.
9. A method as claimed in claim 6, wherein the selecting step further comprises selecting the data rate by comparing a current condition at the physical layer to the data rate tlircshold values.
10. A method as claimed in claim 9, wherein the current condition at the physical layer comprises at feast one of the received signal strength, the signal-to-noise ratio, and the error vector magnitude.
11. A node, adapted for communication in a wireless communication network, and capable of adjusting its rate of communication, the node comprising: a controller, adapted to predict traffic throughput at the node for each of a plurality of potential data rates, convert each of the predicted traffic throughput into a respective target packet completion rate for each of a respective potential data rate, and select the data rate based on an assessment of the actual packet completion rate in comparison with the respective target packet completion rates.
12. A node as claimed in claim 1 1 , wherein: the controller is adapted to predict the traffic throughput for said each potential data rate based on at least pne condition at the physical layer.
13. A node as claimed in claim 12, wherein the at least one condition comprises at least one of the following: expected packet completion rate at each said data rate; transmission time of each data rate, including overhead and variations due to packet length; lime lost due to failed packet transmissions at each said data rate; and queuing delays at each said data rate.
