IoT devices are growing in numbers at a speed as high as ever. The cumulative numbers of IoT devices are expected to reach 75 billion by 2025 with the addition of ~ 10 billion devices each year.
A variety of devices are coming into play (from home appliances to wearables to automobiles to security) with different technical profiles, manufactured by different brands on different standards. There is a need to develop the ability for all these devices to communicate with each other and to make them interoperable.
