1. IoT Network Monitor

2. Typical Sensor Network Setup
End Node
Routable Node
Gateway Node
Wireless Link
LAN/WAN Link

3. Sensor Nodes
These are the embedded development boards for our sensor network. This project is going to use some of these boards.
ARM Cortex M0, M3/4 class CPU
These boards establish low power wireless connections among each other:
Some become end-nodes
Some become router nodes
One or two become gateway nodes
Express Logic provides full IoT/Sensor software stack, from device driver to applications

4. Project Description We need to develop a network monitor.
Each node sends its routing information to the network monitor (through WiFi)
Network monitor graphically displays the network hierarchy
Network Monitor

5. Project Description (Cont)
Ideally the network monitor app runs on iPad
Large display, and light enough for use at trade shows and demos at customer site
Be able to live-update network topology as network changes:
Nodes move around, or nodes enter/exit the network, causing the rest of the nodes to reconfigure.
For Express Logic, this tool allows our customers to better understand our sensor/IoT software product
Typical sensor type of embedded systems don’t have good display
iPad app allows users to see what is happening in the network
Also helps developers to obtain information from each node

6. What Needs To Be Done?
First step: Students develop iPAD application that can display the network hierarchy
Routing table information from each node can be simulated at this step
Second Step: Students develop software routines running on each node to collect routing table information and send information to the Network Monitor (iPAD app)
Third Step: Allow additional statistical data to be sent to the monitor station
traffic, signal strength, power consumption, various counters
At this stage, students have enough knowledge on IoT and network and they may be able to create “out-of-the-box” features!

7. What Express Logic Provides?
Necessary sensor nodes
4 nodes to start with; final demo may consist 10 to 15 nodes
Full software stack running on the sensor nodes
Windows-based development tool (compiler, debugger) for students to develop and debug software on the sensor nodes
Express Logic POC guides students to access internal data structure to obtain routing information or other data necessary for the project
Express Logic POC offers technical assistance in terms of embedded system programming, TCP/IP programming, and knowledge in IoT protocols

8. What Do We Expect From Students?
Familiar with TCP/IP programming
Understand data structure and algorithm
At least one team member is familiar with iOS (iPAD) programming
Alternatively a windows-based app is possible if students are not familiar with iOS
Team members working on IoT nodes need to be familiar with C programming and embedded / real-time systems
We can provide in-depth technical guidance on the embedded side
Knowledge on Sensor Network will help!
