2. Edge Computing

Another pillar for the Internet of Things is cloud computing. However, cloud computing has significant drawbacks such as low bandwidth and possible latency, which may cause issues, especially when real-time data processing is critical. This is why numerous companies are currently investing in edge computing technology.

What is edge computing and why is it beneficial for IoT? Let’s find out.

With cloud computing, data collected from sensors and devices has to travel to the central cloud server to be processed and then sent back to the source of information. As a rule, it travels over long distances and may cause delays.

With edge computing, information gathered by a device is processed directly on that device without being sent to other places. This has become possible due to the increased computing capabilities of modern devices.

Edge computing is decentralized: data collected on devices (on the edge) is not sent to the central server but is processed on these very devices.

Such an approach provides significant bandwidth savings and can ensure better privacy compliance.

Edge computing has much in common with fog computing — another decentralized approach to data processing. The difference is that in fog computing, data is shifted from sensors and devices to fog nodes and processors. These are located closer to end users than cloud servers, e.g. in IoT gateways or LAN networks.

Improved accuracy and speed of data transfer provided by edge and fog computing make more and more companies turn to these technologies. Thus, fog and edge computing for IoT are moving to the forefront in 2020 and further.

3. AI, Big Data and Advanced Data Analytics

For efficient business management, it’s not enough to simply collect information; it’s highly important to thoroughly analyze collected data and make proper data-based decisions.

The increasing number of internet-connected devices is generating tons of complex raw information, and its analysis has become a true challenge for traditional processing techniques. As an example, connected vehicles or manufacturing robots produce terabytes of statistics that require further processing, without which such information is useless.

Only AI-driven analytical solutions have the power to aggregate these huge amounts of information, refine it in real time and draw effective insights. Hence, today’s IoT is inconceivable without advanced data analytics powered by AI algorithms and Big Data technology.

The confluence of artificial intelligence and Big Data is among the top emerging trends in IoT that can provide better outcomes for the industry and transform the way people work.

Moreover, close integration of artificial intelligence, Big Data and smart devices will contribute significantly to protection against security threats.

4. Blockchain

Data security within IoT systems is a critical issue that requires a reliable solution. As of now, blockchain, or distributed ledger technology, seems to be the most suitable tool to ensure proper data protection.

Blockchain is more often looked upon in the context of the Internet of Things data security.

IoT applications are distributed systems in their essence, which is why blockchain technology is a perfect fit for them. Designed for solutions that involve interactions between numerous components, blockchain ensures that accomplished transactions are safely recorded in immutable chains and can be shared across the system without the possibility of alteration.

It has become the norm for financial institutions to protect their operations with the help of blockchain. At the same time, blockchain is currently among the top Internet of Things trends due to its ability to ensure data protection through encryption techniques and peer-to-peer communication without intermediaries.

5. Digital Twins

As the consequence of increased blockchain implementation in IoT solutions, digital twin technology is growing in popularity and becoming one of the main IoT market trends.

Digital twins are virtual analogs of real objects or processes, possessing identical features and functioning the same as their real-life versions.

The reason why blockchain provides a sufficient basis for the functioning of digital twins is in the core attributes of this technology:

  • Auditability
  • Immutability
  • No intermediaries

These features are highly beneficial for digital twins, as they allow the secure transmission of valuable data between virtual and real worlds.

The aim of developing digital copies of physical objects is to make experiments by modeling certain conditions (including emergencies), monitor the behavior of objects and predict the outcome.

Such experiments are extremely useful for the Industrial Internet of Things. For instance, using virtual copies of connected equipment at manufacturing enterprises, you can simulate various situations, predicting positive and negative outcomes. Thus, you can prevent accidents and improve the operational efficiency of physical equipment while it remains intact.

Industrial IoT systems can particularly benefit from digital twins.

Digital twins are likely to become a fundamental pillar for smart manufacturing in the near future.

6. Predictive Maintenance

The concept of predictive maintenance is relevant for IoT solutions both in industrial enterprises and in people’s private lives, which is why this technology will receive increasing investments in the coming years.

How does predictive maintenance work?

  • In industrial equipment, numerous sensors monitor the status of its components, transmitting data to AI-driven software that can analyze it and predict when malfunctions or even failure may occur. Thus, technicians are warned in advance and can replace components before they break down.
  • In smart homes, sensors take all facilities under their control, including electricity, water supply and heating. If problems are detected, such as water leaks or electrical shorts, house owners are warned via an application so that they can quickly take preventive actions.

Predictive maintenance is one of the most powerful emerging trends in Industrial IoT (IIoT).


  • Downtime reduction
  • Costs savings
  • Smooth functioning of equipment
  • Safer working conditions
  • Prevention of serious incidents and damages

Predictive maintenance programs are becoming widely used in manufacturing, logistics, warehousing, healthcare and other areas of IoT application.
