摘要：

Due to the fact that future wireless network will support multi-class services, so it is imperative to differentially treat various kinds of traffic types. Ail adaptive wireless resource management mechanism based on priority is proposed in this paper. Firstly. the mechanism estimates the reserved resource that is needed to support the necessary QoS in teems of handoff call dropping probability, then sets the thresholds according to the priority of various traffic types. The differentiated admission control scheme satisfies QoS requirement of various traffic types and admits high-priority traffic preferentially under high traffic load. The scheme proposed in this paper is simple and adaptive. Finally the paper presents the Markov model of this differentiated admission control, uses the numerical method to analyze the performance of this scheme, and compares the numerical results with simulation data. The results match relatively well.
