应用于医疗的无线人体传感网络媒体接入层设计研究

Exploration of the Design of Media Access Control Layer of Wireless Body Area Network for Medical Healthcare

无线人体传感网络(WBAN)是一项正在受到广泛重视的新技术。通过在人体表面和内部放置一系列的传感器并使用无线通信网络技术,收集心跳、血压、温度等信息来帮助健康监控和疾病诊断。目前,包括美国电子电气工程师协会(IEEE)在内的标准化组织都在致力于这项技术的发展和推广。本文回顾了IEEE成立的IEEE 802.15.6工作组的标准化进程,总结了WBAN设计中关于媒体接入(MAC)层的难点,并在此基础上讨论了减少MAC层功率损耗的方法。

This paper proposes a media access control（MAC） layer design for wireless body area network（WBAN） systems.WBAN is a technology that targets for wireless networking of wearable and implantable body sensors which monitor vital body signs,such as heart-rate,body temperature,blood pressure,etc.It has been receiving attentions from international organizations,e.g.the Institute of Electrical and Electronics Engineers（IEEE）,due to its capability of providing efficient healthcare services and clinical management.This paper reviews the standardization procedure of WBAN and summarizes the challenge of the MAC layer design.It also discusses the methods of improving power consumption performance,which is one of the major issues of WBAN systems.
