Realization of QoS provisioning in autonomic CDMA networks under common utility-based framework

In this paper we present a novel autonomic architecture for CDMA wireless networks, aiming at maximizing overall network's resources utilization while fulfilling various services QoS prerequisites. Founded on a common utility-based framework that provides enhanced flexibility in supporting various and often diverse QoS prerequisites, proper non-convex resource allocation optimization problems concerning both the downlink and uplink of the CDMA system, are set and solved. Then, decentralized algorithms for obtaining system's optimal resource allocation are proposed and used to enable user's QoS-aware selfoptimization functionalities via devising proper control loops that reside at mobile nodes and the base station. Finally, the efficacy of the proposed architecture is illustrated via modeling and simulation.
