In this paper, an IEEE 802.15.6 wireless body area networks (WBAN) medium access control protocol is developed to support a wireless USB (WUSB) application as a protocol adaptation layer (PAL). Due to portable and wearable nature, the WUSB over IEEE 802.15.6 hierarchical medium access control (MAC) protocol has to support the power saving operation and integrate WUSB transactions with WBAN traffic efficiently. In this paper, we propose a Hierarchical Power-saving Method (HPM) for WUSB over IEEE 802.15.6 hierarchical MAC to improve its energy efficiency. Simulation results show that the HPM also integrate WUSB transactions and WBAN traffic efficiently while it achieves high energy efficiency.
