Abstract
Internet of Things (IoT) extends the concept of a digital world into the physical world. This extension will lead the human to be more secure, comfortable and happier than before. The merger of the internet and things also influence the growth of the economy due to its numerous applications. IoT applications cover almost all aspects of human life and make the connectivity possible at anytime, anywhere and to anything in near future. Implementation of this type of connectivity opens many research challenges for the research community. This paper mainly focuses on the different domains of future IoT applications and their research challenges.
