Abstract :
This letter proposes a novel buffer management scheme for improving the packet delivery of Universal Serial Bus (USB) services in wireless networks. In the future, USB may be used with various wireless services, most notably Wi-Fi, thus realizing Wi-Fi USB (WSB). However, data transmission of Wi-Fi and USB is asynchronous due to differences in their Medium Access Control (MAC), resulting in buffer overflow. To alleviate this problem, we propose an overflow prevention scheme where rates of USB transmission are varied depending on status of Wi-Fi. The proposed scheme is evaluated via the NS-3 simulator, showing that the packet delivery ratio of USB data can reach near 100% even in wireless transmission.
