A Distributed Fault Tolerance Mechanism for an IoT Healthcare system
Meriem Zaiter, Salima Hacini · 2020
IoT environment is one of important upshots of IT development; it offers comfort to human daily life. We are interested in our paper in the healthcare IoT field which aims to remotely monitor the patient's health state using a set of physiological IoT sensors. In IoT systems dependability is a strong constraint because the fault occurrence can have a bad consequence on human life. The fault tolerance is one of the mechanisms that can insure a dependable function of the IoT healthcare system. To do this, we improve in this paper the centralized agent based architecture [1] by proposing more robust distributed one. That is by eliminating the weakness due to the centralization of the control. This upgrading is motivated by the fact that the current improvement of the network technologies and the occurrence of new promising paradigms like edge computing and 5G [2] require different reasoning philosophy.
