- Use contiki instant virtual machine, start cooja simulator, create one mote type (Z1) using the file node.c as firmware and another type using gateway.c.
- Place the gateway mote on the grid and at least one node mote, put them in range of each other and click start.
- Install Mosquitto MQTT broker.
- Start broker with
mosquittocommand. - Subscribe to a topic using command
mosquitto_sub -h localhost -t "topic" -v. - Publish messages using the commande
mosquitto_pub -m "test" -t "topic".
- Find a way to avoid loop in the graph.
- Keep routing table of node consistant.
- MQTT part.
- Ping system to check if a node is still in range.
- Subrscriber and publish system for node network.
- Improving perfomance somehow.
- Script to interface the gateway mote with MQTT broker (send publish message from serial to MQTT broker);
- Make node configurable to choose parent with hops or signal strength.
- Sensor data sending system.
- Refactor.
- Fix serial bug (when sending a message to the gateway, the message have to be sent twice, the first time send garbage for an unknown reason).
