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). However, current WBAN protocol still does not have well-defined QoS mapping and resource allocation mechanisms to support multimedia streams with requested QoS parameters. To solve this problem, we propose a novel Resource Management Mechanism (RMM). The proposed method provides fair and adaptive QoS provisioning to isochronous streams according to current traffic loads and their requested QoS parameters through executing a satisfaction of QoS algorithm at WUSB/WBAN host. From simulation results, it is shown that the proposed RMM method improves the efficiency of time-slot utilization while it maximizes QoS provisioning.
