On distributed power control for radio networks
S.C. Chen, Nicholas Bambos, Gregory J. Pottie · 2002
Due to co-channel interference, the carrier to interference ratios (C/I) of some mobiles in a wireless network may drop below a desired quality threshold /spl gamma/, either upon admission of a new mobile or if channel conditions vary. By using dynamic, local measurement of the power gains between base stations and mobiles, we develop a new distributed algorithm for power control which operates by adjusting the transmitted powers from the base stations so as to maintain the C/I of every link above the desired threshold.>
