A new admission control scheme under energy and QoS constraints for wireless networks

— Battery capacity of mobile terminals and radio bandwidth are both limited and precious resources in wireless networks. In this paper, we present a thorough performance study of energy-based admission control scheme to make the best use of these two resources for effective mobile communications. In order to reduce energy consumption of each terminal, we introduce a Victim Selection Algorithm (VSA) and a Beneficiary Selection Algorithm (BSA) for acquiring bandwidth and releasing bandwidth, respectively. To avoid potential compromise of quality of service (QoS) due to the concern of energy consumption in connection admission control, we further propose an adjustment algorithm to statistically meet the demands for QoS. The performance of the proposed schemes is evaluated with respect to energy consumption rate of each successfully transmitted bit, throughput and call blocking probabilities for a variety of traffic such as Poisson and self-similar, multi-class traffic.
