Survey on Smart Personalized Healthcare System in Fog-Assisted Cloud Environments

Abstract

AbstractThe proliferation of the Internet of things has enabled the penetration of many smart devices in order to enhance the life quality of people. As a growing healthcare trend, many enterprises have released their smart wearable personalized healthcare devices to monitor the health status of individuals anywhere at any time. These health devices exploit various IoT sensors to collect the user’s health parameters which has to be analyzed quickly to meet stringent requirements of latency sensitive healthcare applications. The IoT devices are not sufficient for performing such large-scale and compute-intensive analytics due to its resource constraints. Current cloud-based solutions play a significant role in execution of IoT applications, but it has limitations in terms of geographical centralized architecture, multi-hop distance from the data source which adversely affects the latency sensitivity of the IoT services. To combat this issue, the fog computing has emerged as a promising paradigm that provides cloud-like elastic services to the close proximity of end devices. This paper provides detail survey on the concerns and challenges associated with the development of smart personalized fog-assisted healthcare system and highlights the promising future research directions.KeywordsInternet of thingsHealthcare systemFog computingCloud computing
