Abstract
USB has been used at an enormous number of USB devices as a universal interface. Advances in USB and wireless communication technologies have led USB-IF (USB Implementers Forum) to establishment of WUSB(Wireless USB) standard 1.0 that has wired USB's speed and compatibility in addition to wireless technology's convenience. The wireless USB provides convenience. However, due to mobility of WUSB devices in multi-hop environment, DRP (Distributed Reservation Protocol) reservation conflicts happen frequently among devices with three-hop distance. To solve this problem, we propose a new DRP reservation scheme using a new 2-hop range DRP Availability IE for three-hop mobility support in WUSB networks with ultrawideband (UWB) technology. It is shown by simulation results that throughputs of devices at frequent three-hop range DRP reservation conflicts are largely increased.
