444  UAV Networks: Fundamentals and Topologies

444.1 Overview

Unmanned Aerial Vehicles (UAVs), commonly known as drones, are transforming IoT architectures by providing aerial sensing, mobile base stations, and rapid deployment capabilities. UAV networks, particularly Flying Ad Hoc Networks (FANETs), enable dynamic, three-dimensional communication infrastructures for applications ranging from disaster response to smart agriculture.

This chapter series covers the complete foundation of UAV networks for IoT applications. The content has been organized into focused modules for easier learning.

TipMVU: Minimum Viable Understanding

Core concept: UAV networks (FANETs) are flying ad-hoc networks where drones serve as mobile sensor platforms, flying base stations, or data relays that can be deployed in minutes. Why it matters: Drones provide instant coverage where ground infrastructure is destroyed, inaccessible, or too expensive to build permanently. Key takeaway: Choose star topology for simple missions with one control point, mesh for resilient multi-drone swarms, and hierarchical for large-scale operations with ground integration.
