Fast N-screen DRP Reservation for Multi-Hop Wireless U-health Systems

Abstract

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.

A Seamless Screen Switching Scheme for N-Screen Services Based on Context Awareness

“…Furthermore, there have been much progresses in several diverse researches for realizing N-screen services: a multi-hop N-screen traffic mechanism [13] was proposed for a wearable health-monitoring system (WHMS) using a tree topology derived from grouped devices to reduce traffic usage when delivering contents. A seamless N-screen service technology [14] provided the contents using the multipath TCP protocol to improve conventional network transmission scheme, while another seamless N-screen wireless service on a ship area network (SAN) [15] was developed in order to improve throughput and data latency for multi-hop N-screen services, and a multimedia content distribution architecture [16] was suggested for content sharing among neighboring devices through asynchronous content delivery.…”
