A system and method for providing adaptive control of transmit power and data rate in an ad-hoc communication network
WO 2003079611 A8
Abstract
A system and method for selecting an appropriate transmit power and data rate at which a communication signal is transmitted over a link between nodes in a wireless ad-hoc communication network based on factors such as variations in path loss in the link, fading conditions, noise level estimation and overall link quality. The system and method dynamically computes path loss in the link based on characteristics of a message transmitted from the source node (102, 106, 107) to the destination node (102, 106, 107), determines a noise factor at the destination node, and calculates the power level and rate at which the data is transmitted over the link based on the computed path loss and noise factor. Accordingly, the system and method are capable of determining the proper level of transmit power and data rate for assuring that the destination node will receive the data transmitted by the source node at a reliability of at least 90%.
