Abstract

Wireless USB (WUSB) is the USB technology merged with WiMedia PHY /MAC. WUSB can be applied to wireless personal area network applications as well as PAN applications like wired USB. However, due to mobility of WUSB devices in multi-hop environment, DRP (distributed reservation protocol) reservation conflicts happen frequently among WUSB devices with three-hop distance. To solve this problem in large scale WUSB networks, we propose a new DRP reservation scheme using dual role devices and a new Operation Info bits for three-hop mobility support. It is shown by simulation and numerical results that throughputs of WUSB devices at three-hop range hidden DRP reservation conflicts are largely increased.
