SUMMARY
As reiterated by many authors, Internet of Things (IoT) is the network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these things to connect and exchange data, creating opportunities for more direct integration of the physical world into computer-based systems, resulting in efficiency improvements, economic benefits, and reduced human exertions. This is made possible by the communications models with the enabling technologies which make communications possible among IoT connected devices, although, with drawbacks. These drawbacks are the major reasons for adoption problems of IoT services by the society. This paper carried out an investigative study on previous works on the societal applications and adoption problems of IoT; IoT communications models, pros and cons of IoT. Through the study, it was revealed that for IoT devices and services to be widely adopted with no or minimal problems, future IoT technology will not only address the known drawbacks but will require hardware and software components that are highly interoperable, dependable, reconfigurable, and in many applications, certifiable.
