The architecture, inside out.

Edge detection, immersion resilience and opportunistic transmission. No event is ever lost — even when the animal is underwater.

Store-and-Forward Protocol

From the mount to the alert, in six steps.

The male's device decides on its own, at the edge of the network. The cloud only steps in at the end — and only once there's solid ground under the animal.

  1. Deep Sleep

    01/06

    The male's device stays in deep sleep. Only the accelerometer (IMU) monitors kinematics at low frequency.

  2. Event Detection

    02/06

    The mount produces a distinctive kinematic pattern. The accelerometer fires a hardware interrupt that wakes the device.

  3. Validation

    03/06

    The system confirms the animal is out of the water and reads the nearby female's tag over BLE. Proximity validation confirms the mount and rules out false positives.

  4. Local Storage

    04/06

    The event [Male_ID, Female_ID, Timestamp] is encrypted and written to non-volatile memory on the device itself.

  5. Asynchronous Transmission

    05/06

    Back on solid ground, the LoRaWAN radio wakes up and dispatches the accumulated packets to the gateway, with no mobile network costs.

  6. Cloud Processing

    06/06

    The network server forwards the JSON to the backend, which computes the ideal AI window (the AM-PM rule) and notifies the producer.

Container Map (C4 · Level 2)

Three domains, one data line.

From the beacon on the female's sacrum to the producer's phone — without a single piece of mobile infrastructure in between.
