Cross-layer optimization of wireless fading ad-hoc networks

This paper introduces an algorithm to approximately find optimal wireless networks in presence of fading. Joint optimization of application level rates, routes, link capacities, power consumption, and physical layer parameters is considered. The physical layer is interference limited with terminals distributing their power budget between frequency tones, neighboring nodes and fading states. The paper builds on recent results establishing the optimality of layered architectures and develops physical layer resource allocation algorithms that are seamlessly integrated into layered architectures without loss of optimality.
