This chapter discusses the key sixth-generation driving trends elaborating why and how each trend demands a new generation of communication networks. Internet of Things (IoT) envisions to weave a global network of machines and devices that are capable of interacting with each other. The term “Small Data” refers to small data sets representing a limited pool of data in a niche area of interest. Such data sets can provide meaningful insights to manage massive amounts of IoT devices. Self-Sustaining Networks can perform tasks such as self-managing, self-planning, self-organizing, self-optimizing, self-healing, and self-protecting network resources to continuously maintain its Key Performance Indicators. Zero energy IoT devices can harvest energy from the environment to obtain infinite power. Gadget-free communication eliminates the requirement for a user to hold physical communication devices.
