In this paper, the problem of efficient distributed power control via convex pricing of users' transmission power in the uplink of CDMA wireless networks supporting multiple services is addressed. Each user is associated with a nested utility function, which appropriately represents his degree of satisfaction in relation to the expected trade-off between(More)
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(More)
In this paper we address the problem of efficient power allocation in the uplink of CDMA wireless networks supporting simultaneously both real-time and non-real-time services with various and often diverse Quality of Service (QoS) prerequisites. Each mobile is associated with a nested QoS-aware utility function that characterizes its degree of satisfaction(More)
In this paper we address the problem of efficient power allocation in the uplink of CDMA wireless networks, emphasizing on the support of real-time services' QoS prerequisites. The corresponding problem is formulated as a non-cooperative game where users aim selfishly at maximizing their utility-based performance under the imposed physical limitations. A(More)
In this paper the problem of efficient power allocation in the uplink of two-tier closed-access femtocell networks is addressed. The modeling and design approach we follow considers two different dimensions, along with the corresponding constraints and properties that stem from each one of them: a) the two tier architecture, and b) the simultaneous support(More)
