A review of applications, approaches, and challenges in internet of things (IoT)

Abstract

Internet of things “IoT” is now an integral part of our life. Its widespread usage is almost in every application starting from smart home, smart cities, smart farming, remote monitoring, industrial automation, and transport and the list is cumulative. Although this is very useful technology, many challenges are hampering its growth. The crucial challenges faced in the development of IoT are: security, privacy, constrained resources (as first layer in IoT is of sensors and they are quite constrained as far as resources are concerned), interoperability, and integration. Tremendous work has been done in these directions but much more is needed to overcome these barriers. Based on the literature review, this paper provides comprehensive information on IoT, its applications, approaches, and various challenges faced by existing approaches used in smart devices, which in turn can be helpful in finding future prospects.
