Data dissemination in a wireless video surveillance platform for elderly monitoring: Implementation and experiments

Abstract

Nowadays, the number of elderly people keeps growing and represents a non negligible part of the global population in the world. Consequently, healthcare and monitoring expenses destined to them become more and more important. Indeed, receiving ageing people in dedicated infrastructures with qualified staff costs a lot of money either for them and for governments. Also, a large number of elderly prefer continue to live in their own houses rather than joining those healthcare centers. However, they could be subject to domestic accidents and the latters are often detected after a while. This work aims to setup a efficient wireless video surveillance system to help elderly people who need a permanent assistance while they prefer still living in their houses. Our main objective is to early detect and transmit via Internet any abnormal behavior or domestic accident to assistance services. For this, small cameras embedded on wireless home deployed sensors have been considered. Moreover, a simple and lightweight routing protocol for an optimized data transmission have been proposed. The whole system was implemented on an Arduino based platform on which a set of experiments were conducted.
