1552 Network Design and Simulation
1552.1 Network Design and Simulation
This section provides a stable anchor for cross-references to network design and simulation content across the book. The content has been organized into four focused chapters for better navigation and comprehension.
1552.2 Chapter Overview
Network design and simulation are critical phases in IoT system development that enable architects to validate network performance, identify bottlenecks, and optimize configurations before physical deployment. Unlike traditional IT networks, IoT networks present unique challenges including massive scale (thousands to millions of devices), resource constraints (limited power and bandwidth), diverse communication patterns, and stringent reliability requirements.
TipDefinition
IoT Network Simulation is the process of modeling IoT communication networks in software to predict performance, validate designs, and optimize parameters without requiring physical hardware deployment. Simulation enables rapid iteration, cost-effective experimentation, and risk reduction before committing to production infrastructure.
