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.
