What are the Internet of Things Protocols and Standards?

Internet of Things Protocols and Standards

As we all know, the Internet of Things (IoT) covers a range of devices and machines, spanning over a lot of industries from construction to data science and more. Because of this, it can be quite difficult to tie it all together. It can seem extremely daunting to those who have only just started to use this technology but the point of IoT protocols and standards is really quite simple.

Internet of Things protocols and standards exist to tie this massive, diverse technology into protocols and standards that can be used across the board, no matter how extensive (or not) your use of the technology might be. In this article, we’re going to talk about some of the most common protocols and standards that represent most- if not all- IoT devices.

Having a set standard for IoT devices can make it easier for devices across different systems to communicate with one another. In the end, it must makes life easier for us- the users of this new technology. Because the field is still relatively new and evolving, there are thousands of new coalitions and whatnot coming out each day. In this article, we’re going to focus on the most common ones which you should know about. So let’s begin!

Top Five IoT Standards and Protocols You Should Know About

The Internet of Things can do marvels for those who utilise them properly. Since there are so many different types of IoT networks coming out every day, it’s very important that you know what protocols and standards need to be on your IoT network to help further connectivity and transfer of data. Here are the top five IoT standards and protocols which you must have in your network.


MQTT stands for Message Queuing Telemetry Transport. The protocols allows you to establish a publication and subscription based model which is not too heavyweight for the network. This way you can utilise your resources elsewhere as well while ensuring that there’s connectivity between remote locations and your offices. Remote locations have limited connectivity so a heavier protocol might not work there.

2. DDS

DDS stands for Data Distribution Service and it is an IoT standard for machine-to-machine communication in real time where high performance is necessary. It can be used in low powered devices and on the cloud, if you use that for memory storage and communications.

There are two main layers of the DDS standard:

1. DCPS which stands for Data Centric Publish-Subscribe and it allows your subscribers to receive data.
2. DLR which Data Local Reconstruction Layer which is basically an interface which allows tye DCPS to function.

3. Bluetooth

You’re probably familiar with Bluetooth. After all, cell phones have had Bluetooth well before mobile and WiFi was around. Bluetooth is essentially ideal for short range communications. A few decades ago, we used to use Bluetooth to send packets of data in the form of images and text to one another. Now, Bluetooth is handy to connect wireless devices like headphones to your phone, tablet or laptop. So how does this technology help with IoT devices?

We’re glad you asked!

Bluetooth Smart is a protocol created exclusively for IoT devices and applications. It is designed to be ‘low energy’ which is why it is also called Bluetooth Low Energy (BLE). This new innovation is actually helping the IoT market a lor as it is very scalable and flexible. You can use it for a whole range of things, from data transfer to device connectivity and more.

4. WiFi

You’re probably already familiar with WiFi so it really shouldn’t come as a surprise to you that IoT devices need this as well. WiFi allows for wireless networking between devices and transfers large amounts of data in a short span of time. Moreover, you can customize the speed according to your needs and you don’t have to spend a lot of money on it either. WiFi services are so widespread now that it’s very easy to get high speed WiFi services for a very low price.

5. Cellular Technology

It may come as a surprise to you cellular technology is actually a very important part of IoT protocols and standards. Most people associate cellular technology with mobile phones only. After all, it is largely used for communication between phones only. However, because of its range and reliability, you will find that cellular technology is actually quite useful for IoT devices operating over larger distances.

IoT devices can make use of GSM, 3G and 4G to communicate in larger distances where small amounts of information needs to be send quickly. However, it takes a lot of power and its set up and maintenance cost can be quite high.

As you can see, these are some of the most common IoT protocols and standards that all IoT devices and networks, no matter the type, must be equipped with. These help with information transfer, communication and can help your IoT network become more flexible and usable with other devices. We hope you found this article helpful!
