dc.description.abstract Multimedia applications (audio phone, video on demand, video conference, file transfer, etc.) will be integrated into future mobile communication systems. Bandwidth is the most critical resource in mobile multimedia wireless networks. Due to mobile user mobility and limited bandwidth in the mobile wireless communications networks, the quality-of-service (QoS) guarantee becomes very complicated for multimedia applications. Therefore, the available bandwidth of wireless networks should be managed in the most efficient manner. In order to provide mobile hosts (MHs) with highly satisfying degree of QoS in mobile communication systems, new and efficient bandwidth allocation schemes must be developed. In this paper, we propose and evaluate a novel scheme for bandwidth borrowing in mobile multimedia wireless networks. We employ a service-oriented bandwidth borrowing strategy to reduce the overhead of bandwidth reconfiguration and to satisfy QoS requirements of ongoing MHs in cellular systems. Furthermore, we design efficient call admission control algorithms for different multimedia services. The QoS guarantees can be maintained at a comfortable level in cellular systems. Simulation results show that our proposed scheme outperform the previously proposed scheme. en_AU
