An efficient bandwidth reservation and call admission control scheme for wireless mobile networks

With increasing use of mobile units for various applications, it hag become imperative to provide services with quality of service (QoS) guarantees. Efficient utilization of the available bandwidth is an important issue in any QoS provisioning scheme. To this end, we propose techniques for bandwidth reservation and call admission control for wireless mobile networks. Our proposed techniques utilize the available bandwidth efficiently to provide QoS guarantee with reduced new call rejection and handoff call blocking. We have analyzed the performance of our scheme through extensive simulation studies. The results appear promising. (C) 2002 Elsevier Science B.V. All rights reserved.
