dc.description.abstract Link adaptation provides an efficient and flexible strategy to adapt transmission rates based on channel conditions. To attain distributed optimal local and global utility, network interference need to be mitigated therein allowing the users to transmit at the minimum transmission power enough to sustain connectivity. This paper proposes coupled interference network utility maximization (NUM) strategy (i.e. CIN) for rate adaptation in WLANs that is solved using ”reverse-engineering” based on Karush-Kuhn-Tucker (KKT) conditions. The users determine data rates based on their local observations (i.e. coupled interference). Both pricing and limited message passing mechanisms are employed in the NUM wherein pricing restrict users from self-interest behaviours while limited message passing assist users to announce their prices and transmit powers. It is demonstrated theoretically that CIN satisfies the conditions of the super-modular games and that its solution is optimal. Simulation results show that adapting data rates based on the link conditions can improve the performance of ad hoc networks. en_US
