Healthcare Technology Evolution And Adoption Of Fog Computing In Healthcare: Review, Issue And Challenges

Health Information System (HIS) is a combination of hardware, software, process, infrastructure, people and protocol which developed for management healthcare data including collection, storage, analysis, decision making transmission. It supports functional hospital as well provides an infrastructure that support policy decisions over data. HIS grown decade by starting from 1960 to present era divided into four generation versions, HIS. V.1.0 V.4.0. V.4.0 dedicated smart medical technology with fog-based computing system disease-oriented sensing system, IoT, artificial intelligence, high speed internet advanced protocols. Fog Computing distributed framework provide extension cloud computing. lies between sensor (IoT devices) datacenters. This paper presents various generations technologies used in Include review computing, IoT Further this systematic existing research fog issue challenges. Finally, describes comparison edge discussion, open challenges recommendation Fog-based
