  • the Internet of Things also known as Machine Type Communication (MTC) or Machine-To-Machine (M2M) refers to the connection of items to the Internet through information sensing devices for intelligent identification and management.

  • IoT devices With the development of IoT technology, the number of IoT devices will become enormous. These devices will be closely integrated with wireless communication technologies and obtain data through wireless connections or report data to the control center. Thus, a large amount of random or periodic reported data may be generated, which may come from various specific applications, such as wireless water meters, vending machines, pos machines, and the like. The number of users of these applications is large, but the amount of data transmitted in a single transaction is relatively small (usually application layer data is in the range of tens of bytes to hundreds of bytes), and even less than the IP header overhead.
