Abstract A Wireless Body Area Network System for Monitoring Physical Acitivities and Health-Status

Recent technological advances in wireless communications, mobile computation, and sensor technologies have enabled the development of low-cost, miniature, lightweight, intelligent wireless sensor devices or “motes”. A collection of these devices can be placed strategically on the key positions of the human body and connected by means of a wireless network to form a Wireless Body Area Network (WBAN). WBAN has recently attracted a great deal of attention from researchers both in academia as well as industry. This is primarily due to its unique capabilities and promising applications in areas like healthcare, fitness, sports, military and security. In the healthcare domain, WBAN promises to revolutionize healthcare system through allowing inexpensive, unobtrusive, non-invasive, ambulatory monitoring of human’s health-status anytime, anywhere. In this thesis, we propose a WBAN-based prototype system for remotely monitoring mobile user’s physical activities and health-status via the Internet. The system consists of a WBAN and a remote monitoring server (RS). The WBAN comprises a personal server (PS) and a number of custom-made wireless sensor nodes each featuring
