This project investigates embedded technologies for continuous monitoring and logging of vital medical signs and physiological parameters using a wireless body sensor network (BSN). BSNs consisting of a hybrid of implantable, ingestible and wearable sensors have emerged as a new paradigm of digital healthcare for disease alert and real-time monitoring of hospitalized as well as non-hospitalized, chronically-ill or aged patients. This project investigates embedded technologies to deal with unique challenges of a BSN including: extremely stringent energy constraints imposed by in vivo sensors, very limited on-sensor computing capability, and uniquely complex radio propagation body environments. The goal of this research project is to design, optimize and test embedded system communications techniques for wireless BSNs, in order to achieve unprecedented energy efficiency, reliability and cost structure. The proposed research directions and innovative claims include: the design of practical radios for around-body networks and the development of adaptive media access control which is flexible to deal with and capitalize on heterogeneous sensor environments with extremely asymmetric traffic patterns and energy constraints. This project has substantial broader impact. With the technological advances in sensor networks and system-on-chip design, BSNs can be expected to prevail in medical healthcare, but also permeate healthy lifestyles to improve the quality of life in the future. Leveraging the high-profile subjects on communication, networking and embedded systems enjoyed among students, the multi-disciplinary body sensor network research promotes the integration of research with education and outreach activities at both graduate and undergraduate levels.

该项目研究使用无线身体传感器网络(BSN)持续监测和记录生命体征和生理参数的嵌入式技术。由可植入、可摄取和可穿戴传感器组成的BSNs已经成为一种新的数字医疗保健范式，用于疾病警报和对住院和非住院、慢性病或老年患者的实时监测。该项目研究嵌入式技术，以应对BSN的独特挑战，包括：体内传感器施加的极其严格的能量限制，非常有限的传感器上计算能力，以及独特复杂的无线电传播体环境。本研究项目的目标是设计、优化和测试无线基站的嵌入式系统通信技术，以达到前所未有的能量效率、可靠性和成本结构。提出的研究方向和创新主张包括：设计实用的身体周围网络无线电和开发自适应媒体访问控制，该控制可以灵活地处理和利用具有极端不对称的流量模式和能量约束的异类传感器环境。这一项目具有重大而广泛的影响。随着传感器网络和片上系统设计技术的进步，BSNs有望在医疗保健领域盛行，但也将渗透到健康的生活方式中，以提高未来的生活质量。利用学生喜欢的通信、网络和嵌入式系统等备受瞩目的学科，多学科身体传感器网络研究促进了研究生和本科生层面的研究与教育和推广活动的整合。
