According to recent research reports, around 22 billion IoT and wearable devices will be connected to the Internet by 2020. Thus, it is just a matter of time before users begin to experience substantial bottlenecks in IoT connectivity, proficiency, and overall performance.

Currently, a big percentage of connected devices rely on centralized and server/client platforms to authenticate, authorize, and connect additional nodes in a given network. This model is sufficient for now, but as additional billions of devices join the network, such platforms will turn into a bottleneck. Such systems will require improved cloud servers that can handle such large amounts of information traffic. This is already being addressed by the academic and industrial community which is pushing toward decentralized networks. With such networks, some of the tasks are moved to the edge, such as using fog computing, which takes charge of time‐sensitive operations (this will be discussed in detail in chapter 7), whereas cloud servers take on data assembly and analytical responsibilities.
