传感器、低功率微电子和小型化以及无线网络方面的最新技术进步使得能够设计和推广能够自主监测和控制环境的无线传感器网络。传感器网络最有前途的应用之一是用于人体健康监测。许多微小的无线传感器，战略性地放置在人体上，创建一个无线体域网，可以监测各种生命体征，为用户和医务人员提供实时反馈。无线体域网有望彻底改变健康监测。然而，这样的系统的设计者面临着许多具有挑战性的任务，因为他们需要解决往往相当矛盾的要求的大小，操作时间，精度和可靠性。在本文中，我们提出了一个工作的无线传感器网络系统的硬件和软件体系结构的动态健康状况监测。该系统由多个传感器节点，监测身体运动和心脏活动，网络协调器，和个人数字助理或个人计算机上运行的个人服务器。
Recent technological advances in sensors, low-power microelectronics and miniaturization, and wireless networking enabled the design and proliferation of wireless sensor networks capable of autonomously monitoring and controlling environments. One of the most promising applications of sensor networks is for human health monitoring. A number of tiny wireless sensors, strategically placed on the human body, create a wireless body area network that can monitor various vital signs, providing real-time feedback to the user and medical personnel. The wireless body area networks promise to revolutionize health monitoring. However, designers of such systems face a number of challenging tasks, as they need to address often quite conflicting requirements for size, operating time, precision, and reliability. In this paper we present hardware and software architecture of a working wireless sensor network system for ambulatory health status monitoring. The system consists of multiple sensor nodes that monitor body motion and heart activity, a network coordinator, and a personal server running on a personal digital assistant or a personal computer.
