A Human Behavior-Based Routing Protocol in E-Care System

In this paper, the characteristics of network link quality is investigate under the condition of human movement. A new routing metric called dynamic neighbor quality threshold is introduced, which can reflect the dynamic changes of human behavior into traditional routing metric schemes to make the choice of routing path be more sensitive to link changes caused by human behavior. This can be achieved by employing the raw data of acceleration sensors attached on human body. In this paper a human behavior-based routing protocol for wireless sensor networks is proposed. We run a series of experiments in a complex health care environment to evaluate this proposed protocol. Experimental results show that this approach can deduce the energy consumption and achieve a high data arrival rate.
