Short description on how to set-up a sensor network for global IPv6 addresses.
|
||
|
|
NOTE: this assumes that you do not have a native IPv6 connection.
|
||
|
|
|
||
|
|
You will need:
|
||
|
|
* PC with Ubuntu (Linux) - 11 or 12 versions
|
||
|
|
* A node for the RPL-Border-Router (examples/ipv6/rpl-border-router)
|
||
|
|
* A node for the json webservice (examples/ipv6/json-ws)
|
||
|
|
|
||
|
|
Set-up IPv6 tunnel and Border Router
|
||
|
|
------------------------------------
|
||
|
|
1. Ensure that you have gogo6c installed.
|
||
|
|
|
||
|
|
> sudo apt-get install gogoc
|
||
|
|
|
||
|
|
2. Register an account at gogo6 and Freenet6 (http://www.gogo6.com).
|
||
|
|
The account at Freenet6 is needed by the gogo6c client.
|
||
|
|
|
||
|
|
3. Edit the gogoc.conf and set your own Freenet6 user and password by
|
||
|
|
changing the lines with "userid" and "passwd".
|
||
|
|
|
||
|
|
4. Start gogoc at command line
|
||
|
|
|
||
|
|
> cd contiki/examples/ipv6/json-ws
|
||
|
|
> sudo gogoc -f gogoc.conf -n
|
||
|
|
|
||
|
|
This will print your prefix - TSP_PREFIX.
|
||
|
|
In my case TSP_PREFIX=2001:05c0:1517:e400 (prefixlen is 56).
|
||
|
|
|
||
|
|
5. Connect one of the nodes to the PC (via USB or serial) and program
|
||
|
|
it with the RPL-border-router (assumes Z1 node).
|
||
|
|
|
||
|
|
> cd contiki/examples/ipv6/rpl-border-router
|
||
|
|
> make DEFINES=DEFINES=NETSTACK_RDC=nullrdc_driver,NULLRDC_CONF_802154_AUTOACK=1 TARGET=z1 border-router.upload
|
||
|
|
|
||
|
|
6. Run tunslip6 which will forward IP from the RPL network to
|
||
|
|
the IPv6 tunnel (and to the Internet).
|
||
|
|
|
||
|
|
> cd contiki/examples/ipv6/rpl-border-router
|
||
|
|
> make connect-router PREFIX=<TSP_PREFIX>::1/64
|
||
|
|
|
||
|
|
When you start this you should get a printout from the border-router
|
||
|
|
which give you the IPv6 address of it.
|
||
|
|
|
||
|
|
Server IPv6 addresses:
|
||
|
|
2001:05c0:1517:e400:c30c::10a
|
||
|
|
fe80::c30c:0:0:10a
|
||
|
|
|
||
|
|
7. Browse using Mozilla Firefox (or any other browser) to the IPv6 address
|
||
|
|
given by the border router. This will show you the list of other nodes
|
||
|
|
connected to the RPL network.
|
||
|
|
|
||
|
|
http://[2001:05c0:1517:e400:c30c::10a]/
|
||
|
|
|
||
|
|
NOTE: this is a global IPv6 address so it should also be reachable from
|
||
|
|
any machine on the Internet.
|
||
|
|
|
||
|
|
Configuration of COSM submission
|
||
|
|
--------------------------------
|
||
|
|
1. Register a COSM account at https://cosm.com/
|
||
|
|
Set-up a feed and create an API key for the feed.
|
||
|
|
|
||
|
|
2. Program the sensor node with (assumes Z1)
|
||
|
|
|
||
|
|
> cd contiki/examples/ipv6/json-ws
|
||
|
|
> make websense-z1.upload WITH_COSM=1 TARGET=z1
|
||
|
|
|
||
|
|
3. Check the IPv6 address of the node via the RPL-border router or
|
||
|
|
by looking at printouts when booting (make login TARGET=z1)
|
||
|
|
|
||
|
|
4. You need to configure the node to push data to the COSM feed and
|
||
|
|
this can be done in several ways. For convenience a Python script
|
||
|
|
is included that pushes the configuration to the nodes.
|
||
|
|
|
||
|
|
Edit the file 'setcosm.py' and replace "<your-key>" and
|
||
|
|
"<your-feed>" with your COSM API key and COSM feed id. You can then
|
||
|
|
use this Python script to configure your nodes.
|
||
|
|
|
||
|
|
This is an example that configures the node with IP address
|
||
|
|
2001:05c0:1517:e400:c30c::10b to push data to the COSM feed with
|
||
|
|
stream 1:
|
||
|
|
|
||
|
|
> cd contiki/examples/ipv6/json-ws
|
||
|
|
> ./setcosm.py [2001:05c0:1517:e400:c30c::10b] 1
|
||
|
|
|
||
|
|
Another way to configure the nodes is to use a REST add-on for the
|
||
|
|
web browser to post a COSM configuration to the node. "REST Client"
|
||
|
|
for Mozilla Firefox is an example of such add-on.
|
||
|
|
|
||
|
|
POST a JSON expression to your node with the following data:
|
||
|
|
This assumes that you have the feed with id 55180 and want to post
|
||
|
|
to stream 1 in that feed. The field 'appdata' should be set to the
|
||
|
|
API key you created at the COSM web site for the feed.
|
||
|
|
|
||
|
|
{
|
||
|
|
"host":"[2001:470:1f10:333::2]",
|
||
|
|
"port":80,
|
||
|
|
"path":"/v2/feeds/55180/datastreams/1",
|
||
|
|
"appdata":"<insert your COSM API key>",
|
||
|
|
"interval":120,
|
||
|
|
"proto":"cosm"
|
||
|
|
}
|
||
|
|
|
||
|
|
This will configure the node to periodically push temperature data
|
||
|
|
every other minute. You can use GET to retrieve the data to se that
|
||
|
|
the node has been successfully configured (the COSM API key will be
|
||
|
|
visualized as a number of stars).
