Abstract :
A key problem in supporting applications like voice, video and data across wireless networks is managing their different requirements of quality of service (QoS) and the scarce shared bandwidth. QoS mechanisms can provide a differentiated treatment to applications running in different media. We present a QoS management scheme over general packet radio service (GPRS) networks by combining call admission control (CAC), radio resource reservation and scheduling. The simulation results show the effects of the proposed scheme on delay, delay variation and throughput of multimedia traffic while meeting the diversity of QoS requirements of an applications set.
