The Internet of Things (IoT) exemplifies that the network of devices capable of acquiring and sharing the information. Often, these network devices use internet protocol (IP) to communicate with one another. The Internet of Everything (IoE) is an extension of IoT which includes people, process, data and things in network connections. The next evolution is Internet of Nano Things (IoNT) a Nano Technology in which the communication exist between nano scale devices. The Internet of Mission-Critical Things (IoMCT) is used in critical missions such as rescue operations, battlefields, etc. The Internet of Mobile Things (IoMT) is used to communicate the devices using inbuilt mobile sensors. This paper will bring out some relationships between Internet of Things (IoT), Internet of Everything (IoE), Internet of Nano Things (IoNT), Internet of Mission-Critical Things (IoMCT) and Internet of Mobile Things (IoMT).
