Abstract:
As more and more value-added data services are devoloped which require complex quality of service(QoS), this paper defines a wireless access network model with shared buffer and derives mathematical expressions for some QoS parameters. It proposes a joint CAC algorithm considering both packet-level QoS and connection-level QoS. The numerical results proves correctness of the method.
