A Secure Wireless Telehealthcare Monitoring System and its Web Application

Efforts to prepare for a growing number of elderly patients, reducing the escalation of healthcare costs, and avoiding hospitals emergency room overcrowding are some of the driving forces for adopting wireless healthcare monitoring systems. However, due to the open-to-air commination nature of multilayer wireless networks, it is important to consider reliability, accuracy, security and privacy of such data transmission. We have developed a low-cost and wireless telehealthcare system for monitoring of basic physiological parameters and automatically transmitting the measured data to an electronic patient record. It employs off the shelf wireless products and a secure web-based application which have been tested in a hospital with satisfactory outcomes.
