Abstract

Wireless Body Area Network (WBAN) relays on IEEE802.15.6 communication standard optimized for low power and short range communication between wireless medical sensors installed on the patient body that gathers health data (e.g. Heartbeat, SPO2, etc.). In addition, every WBAN has a specific component called gateway that permits to send the measured health datas to remote servers. For long range communications, the gateway is equipped with a 3G/WiFi interfaces. 3G interface allows high Quality transmission of health data during mobility. However, the large amount of 3G data traffic transmitting through this network is expected to grow rapidly with the popularity of mobile applications and therefore degrade the overall service. The aim of this paper is a contribution to improve the Quality of Service (QoS) of ehealth applications to assure an efficient and continuous remote monitoring of patients and elderly. For that, we propose a design of a new context-aware mobility management system that is able to take benefit from multiple available access wireless networks (3G and WiFi) to offload smartly specific traffics and maintain the QoS of critical services such as ehealth services.
上下文感知移动性管理与WiFi/3G卸载的电子卫生无线局域网
无线体域网络(WBAN)采用IEEE802.15.6通信标准,针对安装在患者身体上的无线医疗传感器(如心跳、SPO2等)之间的低功耗、短距离通信进行优化。此外,每个WBAN都有一个称为网关的特定组件,该组件允许将测量的运行状况数据发送到远程服务器。对于远程通信,网关配有3G/WiFi接口。3G接口允许移动期间高质量的健康数据传输。然而,随着移动应用程序的普及,通过该网络传输的大量3G数据流量预计将迅速增长,从而降低整体服务。本文的目的是提高电子健康应用的服务质量(QoS),以确保对患者和老年人进行有效和持续的远程监控。为此,我们提出了一种新的上下文感知移动性管理系统的设计,该系统能够利用多个可用的无线接入网络(3G和WiFi)来卸载智能特定流量并保持关键服务(如电子健康服务)的QoS。
