Protocol bridging, control loops, gateways, state machines, and multi-hop behavior

“An evidence record is the difference between a demo that worked once and a network you can defend.”
1 Control, Gateways & Networked Systems
Protocol bridges, mobile gateways, control processes, PID reasoning, state machines, multi-hop networks, ad-hoc routing, and delay-tolerant networking.
1.1 Start With the Command Path
A control system starts with a simple question: when a device changes state, who is allowed to notice, decide, translate, and act? This guide gathers the chapters that answer that question across bridges, feedback loops, state machines, multi-hop networks, ad-hoc routing, and delay-tolerant delivery.
Read the part as a route through responsibility. First trace the command or telemetry path, then name the boundary that changes protocol, timing, state, or ownership. Start with one gateway and one control decision; the larger network becomes easier once that handoff is visible.
1.2 About This Part
This part keeps the system-behavior chapters together. It focuses on how IoT systems move commands and telemetry across gateways, how control loops behave, and how networked nodes coordinate when the topology is dynamic or intermittently connected.
1.3 How to Use This Material
- Start with gateways when you need protocol conversion and integration boundaries.
- Use control chapters when the question is about feedback, actuator commands, or PID behavior.
- Use networked-system chapters when devices forward for each other, self-organize, or tolerate disruption.
1.4 Learning Resources
The chapters in this part were split from the former large Reference Architectures book so the left navigation remains readable and local to this subject area.
