Fog computing enabled Ambient Assisted Healthcare systems

There is a severe need for continuous monitoring of health condition and behaviour of patients, dependents, and senior citizens. Often such people require continuous presence of medical staff for observing health condition and behaviour. However, unavailability of such medical observers at certain places and at certain locations may result into failure from obtaining sudden spikes in such patient's health parameters and behaviour. In order to prevent such failures, advantage of recent advancements in ICT and IoT can be taken in development of Ambient Assisted Healthcare (AAHC) systems. AAHC systems provide self-care support to people suffering with health problems or disabilities. Cloud computing enabled AAHC systems are available. However, study suggests that evolution of intelligent devices and fog computing has coined many crucial challenges against the cloud computing based solutions. Fog computing helps overcome such deficiencies. A detailed review of fog computing based existing AAHC systems is presented in this paper.
