A Review on Several Critical Issues and Challenges in IoT based e-Healthcare System

Due to recent development in smart/ electronic devices or computing devices, a lot of data (called Big Data) is being generated. This data in simple terms is called as "Large Data" or "Big Data". Today’s Big Data is highly useful for predicting future (with respect to an application) after having a proper and valid analysis. Together this, several researchers have been tried to make efficient analytics tools (or techniques like data mining or machine learning) to analysis this Big Data, but some tool fail due to the volume and veracity feature of the big Data. So, there are several problems, issues and challenges have been rectified which are need to overcome in near future. Hence, this article gives insight to where and how big data can be used in health care system, also provide several challenges and issues with respect to genomic analytics (on this collected data).
