AI 中文摘要
人体区域网络是一种用于人体表面、内部或周边近距离的短程、低功耗且高度可靠的无线通信的无线电通信协议。结合各种生物医学传感器,它能实时收集和监测生理信号,被视为治疗和预防慢性病以及老年人健康监测的重要技术。IEEE 802 LAN/MAN标准委员会于2007年12月批准了任务组TG15.6,经过四年多努力,TG15.6于2012年2月发布了首个BAN国际标准IEEE Std 802.15.6。在该标准制定过程中,标准化组与研究界充分合作,尤其是对BANs的无线电传播机制研究投入巨大。由于无法对人体进行体内测量,植入通信面临技术挑战,需借助复杂的计算机模拟。本文概述了为获得支持BANs中植入通信标准化且准确的传播模型所做的一些研究。还介绍了当前通过使用超宽带信号用于可植入设备以及在动物身上进行物理测量来增强IEEE Std 802.15.6信道模型的研究。
英文摘要
A body area network is a radio communication protocol for short-range, low-power, and highly reliable wireless communication for use on the surface, inside, or in the peripheral proximity of the human body. Combined with various biomedical sensors, BANs enable realtime collection and monitoring of physiological signals. Therefore, it is regarded as an important technology for the treatment and prevention of chronic diseases, and health monitoring of the elderly. The IEEE 802 LAN/MAN Standards Committee approved Task Group TG15.6 in December 2007. As a result of more than four years of effort, in February 2012, TG15.6 published the first international standard for BANs, IEEE Std 802.15.6. Throughout the development of this standard, ample collaboration between the standardization group and the research community was required. In particular, understanding the radio propagation mechanisms for BANs demanded the most research effort. Technical challenges were magnified for the case of implant communication because of the impossibility of conducting in-body measurements with human subjects. Therefore, research in this field had to make use of intricate computer simulations. This article outlines some of the research that has been done to obtain accurate propagation models supporting the standardization of implant communication in BANs. Current research to enhance the channel models of IEEE Std 802.15.6 through the use of ultra wideband signals for implantable devices along with physical measurements in animals is also presented.
