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) ## Application Architecture See attached image ndn-pi_application_architecture.png ## 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
