A hierarchical system of wireless USB (WUSB) over wireless body area networks (WBAN) is adopted for wearable health-monitoring systems (WHMS). It is executed on the basis of WUSB over WBAN protocol at each wearable sensor node comprising the WHMS. Basically, a single WHMS operates based on WUSB over WBAN protocol. And the multiple WHMSs operate based on the WiMedia D-MAC protocol and dual-role device (DRD) function. In this paper, a multimedia streaming scheme for N-screen services is proposed for WHMS networks. In a hospital, N-screen applications must be required by using WHMS networks. The multimedia streaming scheme for N-screen services is composed of service interval-based resource allocation and multicast reservation schemes. In simulation results, efficiency of the multimedia streaming scheme is proven through throughput and delay performances at an N-screen service scenario.
