An Elderly Health Care System Using Wireless Sensor Networks at Home

Abstract

The purpose of this project is to integrate the technologies of wireless sensor networks and public communication networks to construct a healthcare system for senior citizens at home without interfering their daily activities. This system provides 4 main functionalities, including indoor monitoring, outdoor monitoring, activity and health state decision, emergency decision and alarm. JTH has developed a prototype of wireless sensor networks, an interconnection platform and a service management platform to support large scale data interconnections and real-time activity and health state reports to related persons (e.g. doctors or nurses, elder-self, elderspsila relatives) via all popular communication approaches, such as automatic voice telephone call, SMS or Email etc. In this paper, the system functions and implementation approaches are introduced. A series of experiments results shows that the system performs high validity and reliability.
