1. Introduction
The elderly or people with disabilities want to remain in their homes even when their
health condition has been getting worse [1]. The global population of people over the
age of 65 is expected to more than double from 375 million in 1990 to 761 million by
2025” [2]. With this, the telehealth service has been widely implemented and used to
help one (refers to elderly or individual with disability) to live independently at home.
As the problem of aging and disability are converging, the smart home based health
monitoring has become a key research area for ubiquitous and embedded system
computing.
