A QoS Provisioning Mechanism of Real-Time Wireless USB Transfers for Smart HDTV Multimedia Services

Wireless USB (WUSB) is the USB technology merged with WiMedia PHY/MAC. WUSB can be applied to WPAN applications as well as PAN applications like wired USB. However the current WUSB protocol can’t provide resource allocation scheme to respond to changes of available resource as well as resource allocation scheme for saturated wireless channel. This problem causes the critical problems in QoS provisioning to multimedia streams, since multimedia application generate high data rates and can easily saturate the bandwidth even at the rates provided by UWB transmissions. Therefore, we propose resource allocation scheme to respond to changes of available resource as well as resource allocation scheme for saturated WUSB channel.
