无线集成传感器网络的概念已经应用于我们日常生活的几个领域，如安全、交通和环境监测，也可以为医疗服务提供先进的监控资源。通过无线联网医疗传感器，将它们连接到患者体内，我们创建了适当的基础设施，以便在不使患者感到不适的情况下对患者进行持续和实时的监测。这一基础设施可以通过提供灵活获取生命体征的手段来改善医疗保健，同时为患者提供更多便利。考虑到无线网络的类型，传统的媒体访问控制(MAC)协议无法利用医学传感器网络中出现的特定应用需求和信息特性，如对低功耗的需求以及相当有限和不对称的数据流量。本文提出了一种支持医学传感器无线网络的低功耗MAC协议的体系结构。该协议旨在通过利用固有的应用功能和要求来提高能源效率。它着眼于避免主要的能量浪费源，如空闲收听、碰撞和电力消耗。
The concept of a wireless integrated network of sensors, already applied in several sectors of our everyday life, such as security, transportation and environment monitoring, can as well provide an advanced monitor and control resource for healthcare services. By networking medical sensors wirelessly, attaching them in patient's body, we create the appropriate infrastructure for continuous and real-time monitoring of patient without discomforting him. This infrastructure can improve healthcare by providing the means for flexible acquisition of vital signs, while at the same time it provides more convenience to the patient. Given the type of wireless network, traditional medium access control (MAC) protocols cannot take advantage of the application specific requirements and information characteristics occurring in medical sensor networks, such as the demand for low power consumption and the rather limited and asymmetric data traffic. In this paper, we present the architecture of a low power MAC protocol, designated to support wireless networks of medical sensors. This protocol aims to improve energy efficiency by exploiting the inherent application features and requirements. It is oriented towards the avoidance of main energy wastage sources, such as idle listening, collision and power outspending.
