USING NODE-RED For loT And Edge Computing

All of us make use of lof in one way or the other today, and this usage will only grow in the near future. This article details how Node-RED, a powerful and easy-to-use programming platform, helps in implementing loT and edge computing

The Internet of Things (IoT) is omnipresent in today's world. A few fields where it is dominant are listed below.

Smart health and medical services. Smart ambulances, hospital management, intelligent drug control, etc.

Smart cities.

Smart traffic control, smart toll plazas, pollution monitoring, water quality management, self-driven cars, drones, law enforcement, energy conservation, etc.

Personal applications. Smart health gadgets, theft avoidance, controlling home appliances, etc.

Retail sector. Automated checkout, logistics monitoring and management, etc.

Agriculture. Analysis of crops, dynamic water distribution, smart irrigation, farm surveillance, drones for smart farming, agriculture robots, etc.

Many other domains, too, are associated with the field of IoT, especially where intelligent robotic applications are being developed.

The Internet of Everything (IoE) is another term used for smart applications, and is the integration of IoT with the cloud and the World Wide Web for the real-time connectivity of devices.

A number of programming platforms are available for working with IoT, IOE, fog or edge scenarios. Hundreds of toolkits, which are very powerful and easy to use for dynamic research, are available as well. A few of these are listed in the Table.
