Ultra-wideband (UWB) technology has emerged as a solution for the wireless interface between medical sensors and personal servers in future telemedicine systems. The WiMedia Alliance has specified a distributed medium access control protocol based on UWB for high-rate WPANs. In the cases of some applications, data traffic between the source device and destination device is transmitted via one or more...
Wireless USB (WUSB) is the USB technology merged with WiMedia PHY /MAC based on success of wired USB, and it can be applied to various mobile applications such as laptop, cellular phone, etc. However the current WUSB protocol can't recover the link breakage occurred between WUSB host and device. This problem causes the critical problems in QoS provisioning to isochronous streams and mobile applications...
In this paper, we propose relay transmission protocol based on SoQ(Satisfaction of QoS) for QoS enhancement and analyze the performance of the proposed method in Wireless USB Networks. In the proposed protocol, Wireless USB host executes the Satisfaction of QoS (SoQ) time slot allocation algorithm. And, in order to give devices with scarce resource another chance to improve QoS, the proposed relay...
