Part 3: A Canopy Network Coordinated through IBM Watson IoT
Goal
Deployment
The canopy network serves as a backbone for the low-power wireless mesh network you are deploying throughout your building. It consists of a number of SmartMesh IP managers connected to raspberry Pi single board computers, and a some DC9018 boars deployed on different floors of your building.

different DC2274+raspberry Pi gateways are installed on different floors | a number of DC9018 provide coverage to the entire floors |
|---|
The low-power wireless network in each floor is independent. They do, however, share the same netid. This means your mote can attach any of the networks.
Networking Architecture of the Canopy Network
The following diagram shows the networking architecture of the canopy network: each gateway device is connected to the IBM Cloud, to which your Node-RED instance connects.
Crash Course 33.3.1 (given by your instructor)
Ask away until you have a good understanding of how the canopy network is put together.

Visualizing the Network Topology
stars.solsystem.io is a website which shows the topology of the canopy network
Crash Course 33.3.2 (given by your instructor)
Walk around your building with a mote. On each floor there is a canopy network, switch on your mote and verify:
that it successfully joins network (look at the LEDs)
that it appears on stars.solsystem.io
Navigation
-
Part 0a: Things to prepare before the session — Things to install on your computer and on your IBM Cloud instance before coming to the session.
-
Part 0b: Getting Started! — Overview of the hardware you will be using, and of the general organization of the unplugfest.
-
Part 1: Your First Standalone Network — Build your very first network, understand how the LEDs indicate the state of the motes, issue simple CLI commands on the manager, understand the use of the netid.
-
Part 2: Understanding Trade-Offs in SmartMesh IP — Understand how latency, data rate and energy trade off for one another.
-
Part 3: A Canopy Network Coordinated through IBM Watson IoT — How the canopy network, which is already deployed in your building works.
-
Part 4: Interact with Sensors and Actuators — Connect sensors and actuators to your mote, and interact with them from your Node-RED instance in the IBM Cloud!
-
Part 5: Programming Challenge — Once you have completed Part 4, sky is the limit. Explore a couple of possibilities where to go from there.
