Protocols

There are various protocols out there that could be used in AOWIS:

• MQTT - lightweight publish/subscribe messaging for telemetry and asynchronous updates
• AMQP - robust messaging with guaranteed delivery, suitable for HQ/Farm Controller links
• Zigbee - low-power mesh networks for local sensors and actuators
• LoRa/LoRaWAN - long-range, low-power communication suitable for large farms and sparse sensor deployments
• Z-Wave - low-power mesh for home/farm automation devices and actuators
• EnOcean - energy-harvesting wireless sensors and switches

Research will be needed to be done here to decide which of these we could or should focus on while building AOWIS.
