Distributed computing based ultra-low power consumption WSN for monitoring elderly people

Abstract

The number of elderly people living alone is increasing in Japan. Consequently, the budget for social security is increasing as well. Moreover, the “in-house” health care for senior citizens is gathering much attention in Japan. Various “home-care” products are increasingly developed and implemented to take care of the health of elderly people. However, these products are usually expensive and their installation is very difficult. In this research, we developed a wireless sensor network system that is easy to install and to operate. Our preliminary experiments demonstrate that our system can surely find some anomaly sensing information without any difficult installation procedures. Many WSN research was not important of power management of sensor nodes. In this research, we present an ultra low-energy consumption sensor system that is deployed as a distributed computing system.
