6top Example Description
A RPL+TSCH node will act as basic node by default, but can be configured at startup using the user button and following instructions from the log output. Every press of a button toggles the mode as 6ln, 6dr or 6dr-sec (detailled next). After 10s with no button press, the node starts in the last setting.
The modes are:
- 6ln (default): 6lowpan node, will join a RPL+TSCH network and act as router.
- 6dr: 6lowpan DAG Root, will start its own RPL+TSCH network. Note this is not a border router, i.e. it does not have a serial interface with connection to the Internet. For a border router, see ../border-router.
- 6dr-sec: 6lowpan DAG Root, starting a RPL+TSCH network with link-layer security enabled. 6ln nodes are able to join both non-secured or secured networks.
6top Operation
If the mode is 6ln (node)
- The application triggers a 6P Add Request to 6dr (neighbor)
- Following this the application triggers another 6P Add Request to 6dr
- After an interval, the application triggers a 6P Delete Request to 6dr
For the Cooja simulation, you may use the rpl-tsch-sixtop-z1.csc file in this folder. Once you run the simulation, "Mote output" window of Cooja simulator displays the following messages.
For a 6P Add transaction, ID:1 TSCH-sixtop: Sixtop IE received ID:1 TSCH-sixtop: Send Link Response to node 2 ID:2 TSCH-sixtop: Sixtop IE received ID:2 TSCH-sixtop: Schedule link x as RX with node 2 ID:2 TSCH-sixtop: Schedule link x as TX with node 1
Similarly for a 6P Delete transaction.
