The Internet of Things (IoT) for short has recently gained much traction due to its potential for transforming business applications and everyday life. IoT can be defined as a network of computationally intelligent physical objects (any object such as cars, fridges, industrial sensors, and so on) that are capable of connecting to the internet, sensing real-world events or environments, reacting to those events, collecting relevant data, and communicating it over the internet.
This simple definition has enormous implications and has led to exciting concepts, such as wearables, smart homes, smart grids, smart connected cars, and smart cities, that are all based on this basic concept of an IoT device. After dissecting the definition of IoT, four functions come to light as being performed by an IoT device. These include sensing, reacting, collecting, and communicating. All these functions are performed by using various components on the IoT device.
Sensing is performed by sensors...
