This is a software prototype for a social distancing application using TinyOS and Node-Red and test it with Cooja. The application is meant to understand and alert you when two people (motes) are close to each other.
The operation of the software is as follow:
- Each mote broadcasts its presence every 500ms with a message containing the ID number.
- When a mote is in the proximity area of another mote and receives 10 consecutive messages from that mote, it triggers an alarm. Such alarm contains the ID number of the two motes. It is shown in Cooja and forwarded to Node-Red via socket (a different one for each mote).
- Upon the reception of the alert, Node-red sends a notification through IFTTT1 to your mobile phone.
We used at least 5 motes to test the application, starting the simulation with all the mote far away from each other and moving them with the mouse testing different configurations.
