In this paper, we propose a multimedia streaming scheme by using the proposed N-screen resource allocation and N-screen DRP Availability Information Element, for n-screen service in Wearable health-monitoring systems (WHMS) networks. The proposed scheme can improve throughput performance of WHMS Vital Video (WVV) applications. Also, proposed scheme can reduce WVV delay since it minimizes the multicast WVV data delivery process. Compared with the legacy WHMS system, the proposed streaming scheme is very simple and efficient as it does not require additional hardware. These merits make the proposed WHMS system extremely inexpensive to implement in hospital WHMS network and bio cloud-computing applications.
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 multi-hop N-screen traffic mechanism is proposed for WHMS networks. In a hospital, N-screen applications must be required by using WHMS networks. The multi-hop N-screen traffic mechanism is composed of a coordinated resource allocation and an N-screen multi-hop DRP Information Element. In simulation results, efficiency of the multi-hop Nscreen traffic mechanism is proven through multi-hop link establishment success rate and delay performances at a WHMS network service scenario.
