摘要：
According to the characteristics and QoS requirements of different types of service flows, this paper proposes a dynamic, prediction-based, multi-class, adaptive bandwidth reservation scheme for IEEE 802.16 (WiMAX) networks. The scheme adopts different bandwidth reservation and admission control policies to different types of service flows and therefore guarantees that the real-time sessions have higher priorities than non real-time sessions and that handover sessions have higher priorities than new sessions. In addition, a bandwidth reservation adaptation algorithm is also proposed. The algorithm adjusts the amount of bandwidth reserved for handover sessions according to the current network conditions thus creating a balance between new session blocking rate and handover session dropping rate.
