IoT-based location-aware smart healthcare framework with user mobility support in normal and emergency scenario: a comprehensive survey

Abstract The technological ecosystem built up with the collaboration of sensors, smartphones, Cloud, Internet of Things (IoT), machine learning, deep learning, etc., functions toward societal benefit in terms of smart healthcare to world population irrespective of demography. IoT-based healthcare is getting immensely popularized because it is cost-effective, user-friendly, intelligent, and efficient providing location-aware support both in normal and emergency scenarios. Here functional framework of IoT-based healthcare with the state-of-the-art literature survey has been illustrated, followed by location-aware protocols, learning techniques for intelligent healthcare, and future research directives igniting interests of researchers in this emerging domain.
