MQTT and The Internet of Things (IOT)

Home network and Internet

The first wave of the Internet involved connecting people to each other and people to information.

The next wave of the Internet will involve connecting the physical world to the Internet, and machines to each other.

Every object, both real and virtual, connected to, and accessible over the Internet is the basic idea of the Internet of Things (IOT) or the internet of Everything (IOE).

Today we have the Smart phone tomorrow the smart car and the smart home.

All of these devices will be made Smart by connecting them together with other systems via networks, and the Internet.

Messaging protocols, using protocols like MQTT, will have an important role to play.

The purpose of this site is to help you learn about:

  • Basic networking and networking protocols
  • MQTT and MQTT Brokers
  • Network Programming Python and Node.js

If you have any questions please ask
