Abstract

This paper proposes a link adaptation algorithm (LAA) for ad hoc networks based on coupled interference minimization whereby network interference is dynamically controlled by adjusting the transmit power. Such adjustment exploits link status and hence, users are aware of channel conditions as they determine the data rates. Users are encouraged to maximize utilities of others as they maximize their own due to forced cooperation resulting from the pricing/costing effect attached to transmit power choices. This is equivalent to super-modular game, thus, network utility maximisation (NUM) problem is formulated and analysed using such tool.
