Abstract :
Certified Wireless Universal Serial Bus (WUSB) is one of different varieties of Wimedia standard for distributed medium access control (MAC) protocol for ultra wide band (UWB) communications in the wireless personal area network (WPAN). To the best of our knowledge, no technical contributions exist in the open literature at present simulating WUSB and its performance. In this paper, we investigated the performance of the WUSB standards and compared it to the Wimedia Standard using NS-2. The study showed that WUSB can achieve better throughput and more accurate timing control of device activity than using the standard facilities of the WiMedia MAC. Our paper also addressed protocol extensions and improvement to the original WUSB standard to support better Quality of Service (QoS) by adding priority, adaptive packet loss technique and adding backup host selection to prevent mobility failures.
