Raspberry Pi IoT Status
=======================
!ndn-pi_application_architecture.png!
On each Pi, get:
* ndnx (just compile locally, doesn't take long)
* PyNDN2
* ndn-pi
* libcec (only needed on HDMI-CEC node)
Devices:
* NDN-PI-HDMI-CEC-1: 131.179.196.225 (WAN), 192.168.1.1 (LAN)
* NDN-PI-OCCUPANCY-1: 192.168.1.2 (LAN)
* NDN-PI-OCCUPANCY-2: 192.168.1.3 (LAN)
## Full Example
In order to ssh into gateway pi (HDMI-CEC), must be on CS dept network. ssh into CS dept server first or be physically there.
Run the following in order.
Window 1 (Occupancy Node 1)
ssh pi@131.179.196.225
ssh 192.168.1.2
nfd-start
nfdc register /home 2
sudo python app/occupancy_node_1.py
Window 2 (Occupancy Node 2)
ssh pi@131.179.196.225
ssh 192.168.1.3
nfd-start
nfdc register /home 2
sudo python app/occupancy_node_1.py
Window 3 (HDMI-CEC Node)
ssh pi@131.179.196.225
nfd-start
nfdc register /home 3
python app/hdmi_cec_node.py
Window 4 (Consumer Node, physically, same node as HDMI-CEC Node)
ssh pi@131.179.196.225
# don't start nfd here since already started
python app/consumer.py
## Future Work
Ask Jeff for prioritization
### Enable ethernet faces in NFD
NFD supports ethernet faces and we want to move away from IP dependency. Enable etnernet faces in NFD, cross-compile, and install on pi. Change nfdc register /home 2|3 command to use ethernet face. You might want to back up the current working NFD on the pi (in /usr/local) in case anything goes wrong in the cross-compile/install.
### Web interface gateway
Use ndn-js and Node-JS. Display sensor data in an organized fashion and expose control of networked devices remotely. Connect gateway to ndn testbed listen for names /ndn/<home-address>/home/... and translate /home/...
### Webcam Node
Leverage NDN-RTC code to capture and publish video as data. Consume this with the HDMI-CEC node and display on the TV.
### Integrate bootstrapping into application
app/bootstrap.py and app/gateway.py have pseudocode that can be combined with Wentao's key distribution ideas
