Abstract
In this paper a scheduling mechanism is provided within a proposed UMTS access network architecture, employed to perform a QoS experiment. W-CDMA is the strongest candidate for the air interface technology of UMTS which will comprise both a terrestrial part (T-UMTS) and a satellite part (S-UMTS). Dynamic Resource Scheduling (DRS) is proposed as a framework that will provide QoS provisioning for multimedia traffic in W-CDMA systems. The proposed resource allocation algorithm, applied with a congestion control mechanism, allows the access network to guarantee the appropriate QoS contract agreed at connection set-up between the users and the UMTS access network operator, obtaining a fair distribution of the available resources between the users and a high link utilization. OPNET 7.0 has been used to carry out and analyze the experiment results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
