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.
