  The Internet of Things has received a lot of research attention. It is
considered part of the Internet of the future and is made up of billions of
intelligent communication. The future of the Internet will consist of
heterogeneously connected devices that expand the world boundaries with
physical entities and virtual components. It provides new functionality for
related things. This study systematically examines the definition,

Things. We will introduce various definitions of the Internet of Things. Then,
it will be discussed new techniques for implementing the Internet of Things and
several open issues related to the Internet of Things applications will be
investigated. Finally, the key challenges that need to be addressed by the
research community and possible solutions to address them are investigated.
