In order to provide seamless multimedia services in the next-generation wireless networks, efficient bandwidth reservation scheme must be developed. A novel attribute-based bandwidth reservation scheme is proposed in this paper as a solution to support quality-of-service guarantees (QoS) in the mobile multimedia wireless networks. Based on the existing network conditions, the proposed scheme makes an adaptive decision for bandwidth reservation and call admission in each base station (BS). We use the dynamically adaptive approaches to reduce the connection-blocking probability (CBP) and connection-dropping probability (CDP), and to increase the bandwidth utilization (BU) for mobile multimedia wireless networks. Simulation results show that our proposed scheme outperform the previously proposed scheme in terms of CBP, CDP, and BU in mobile communication systems.
