The IoT protocol stack explained as a modular architecture — device, transport, messaging, and semantic layers, with how to choose MQTT, CoAP, or OPC UA.
Unified Namespace (UNS) for industrial data in 2026 — Sparkplug B 3.0, ISA-95 alignment, HiveMQ vs EMQX vs NanoMQ benchmarks, and a fully refreshed UNS reference architecture.
Sparkplug B 3.0 edge of network architecture for production IIoT — topic namespaces, primary/secondary hosts, store-and-forward, MQTT 5 mapping, and 2026 deployment patterns.
Step-by-step OPC UA PubSub over MQTT 5 implementation — DataSetMessage mapping, JSON vs UADP, security profiles, and a working aiomqtt + asyncua tutorial for 2026.
DDS vs MQTT vs OPC UA in 2026 — QoS, discovery, security, broker vs brokerless, and a decision matrix for picking the right industrial messaging protocol by use case.
MQTT 5.0 features that actually move the needle — shared subscriptions, topic aliases, flow control, user properties, reason codes, and the 2026 production patterns to use them.
The 2026 map of IoT and industrial communication protocols — MQTT, OPC UA, Modbus, CAN, Ethernet/IP, BACnet, LoRaWAN — and how to pick the right stack by layer and use case.
