Control, Gateways & Networked Systems

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

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 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.

1.2 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.

1.3 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.
