Our use case was a smart home that would have devices monitoring 'stats' in a room (eg temperature, light, CO2 levels, etc.), could control 'apparatus' in the room (machines that could affect the rooms stats) and could communicate with each other if needed.

Overview

1. SmartHome's have rooms and devices in the rooms. They are the network. You can run one with the command below, and can then use the terminal to interact with devices. (To satisfy project requirements, start with 5 rooms per SmartHome, which will create 5 devices on the network. You can start a network on any Pi)

python3 SmartHome.py --home_id=1 --rooms=5

2. Once SmartHome is running, you can monitor device logs like this:

tail -f home_1/device_logs/room_0_device.log

3. You can also monitor room stats and apparatus like this:

python3 RoomMonitor.py

4. You can run the untrusted device using the command below. This will create a device that doesn't join the network officially like the other nodes, therefore it will have its packets ingnored.

python3 UntrustedDevice.py

Demo Instructions

1. Check requirements

1. Make sure requirements are installed (just pandas)

pip install -r requirements.txt

2. Set Up the Demo

1. Open a terminal on the Pi and run the following script/command to create a SmartHome instance and to create missing directories and log/stat files:

   python3 SmartHome.py --home_id=1 --rooms=5

2. Open a new terminal in the same directory on the same Pi and run the following command to view the logs of Room_0:

   tail -f home_1/device_logs/room_0_device.log

3. Open a new terminal in the same directory on the same Pi and run the following command to view the logs of Room_1:

   tail -f home_1/device_logs/room_1_device.log

4. Open a new terminal on the same Pi and run the following script/command to create an UntrustedDevice instance:

   python3 UntrustedDevice.py

   Then input 1 when prompted for a home id.

5. Open a new terminal on the same Pi and run the following script/command to view the logs of UntrustedDevice:

   tail -f home_1/device_logs/untrusted_device.log

3. Demo Scenarios

Scenario 1: A node leaves and re-enters the network.

1. In the first terminal that is running the SmartHome instance, enter 0 to choose the device in Room_0.
2. Enter turn off to turn the device off.
3. Notice activity in logs of Room_0 and Room_1.
4. Enter turn on to turn the device on.
5. Notice activity in logs of Room_0 and Room_1.

Scenario 2: A node sends an interest packet for a data name that exists.

After the steps of scenario 1, the first terminal that is running the SmartHome instance should still be in the menu for Room_0.

1. Enter send interest to bring up destination options
2. Enter 1 to select Room_1 as the destination of the interest packet.
3. Enter temp to send the interest packet for data room_1_device/temp.
4. Notice activity in logs of Room_0 and Room_1. Room_0 sends the interest packet, which Room_1 receives. Then Room_1 sends a data packet with the requested data, which Room_0 receives.

Scenario 3: A node sends an interest packet for a data name that does not exist.

After the steps of scenario 2, the first terminal that is running the SmartHome instance should still be in the menu for Room_0.

1. Enter send interest to bring up destination options
2. Enter 1 to select Room_1 as the destination of the interest packet.
3. Enter foobar to send the interest packet for data room_1_device/foobar that doesn't exist.
4. Notice activity in logs of Room_0 and Room_1. Room_0 sends the interest packet, which Room_1 receives. Then Room_1 sends a data packet saying room_1_device/foobar doesn't exist, which Room_0 receives.

Scenario 4: A node receives a packet with unknown encryption.

1. In the terminal that is running the UntrustedDevice instance (the 4th one opened), enter 0 to choose the device in Room_0.
2. Enter temp to send the interest packet for data room_0_device/temp.
3. Notice activity in logs of Room_0 and UntrustedDevice. UntrustedDevice sends the interest packet, which Room_0 receives. Room_1 outputs that a packet with unknown encryption was received and discards the packet. Note that UntrustedDevice never receives anything back.

4. Close up terminals when finished, and give us a good grade!
