Abstract

The guarantee of quality of service (QoS) is a key issue for multimedia streams in wireless multimedia communications. QoS parameters required by most of multimedia streams are ranges or in set, [QoS_min, QoS_max]. Computer systems and network systems must allocate enough resources such as CPU, I/O, memory and bandwidth to meet these QoS parameters. These resources are dynamic variations in availability, e.g., bandwidth on radio during multimedia stream transmission. The adaptive session is defined to formularize multimedia stream. It can allocate resources with QoS_min, during establishment of a multimedia stream call and it can dynamically adjust its QoS parameters in [QoS_min, QoS_max] by PID to adapt the variations in resource availability during multimedia transmission. It not only meets the QoS parameters required, but also improves the useful of resources
