Internet of Things (IoT) Testbed

CENT’s IoT testbed setup started in the Fall/2017 semester and will continue throughout the Spring/2018 semester. When it is ready, the complete testbed will have a structure as depicted in Figure 1.

The testbed provides infrastructure for experiential learning and research for IoT. Among its principal components, we have: i) Several connectivity options for sensor and systems ( wired Ethernet, Wi-Fi, and LoRaWAN), ii) machine to machine communication with a focus on MQTT, and iii) a storage and processing cluster leveraging ThingsBoard, an ELK stack (Elasticsearch, Logstash, Kibana), and Kafka.

Our connectivity infrastructure includes a dedicated IoT SSID available in Hinds Hall, two LoRaWAN gateways, one located in Hinds Hall and the other on top of a 20 story building in downtown Syracuse, and a core network in the CENT lab on the second floor of Hinds Hall.

The LoRaWAN infrastructure covers all of metro Syracuse and most of the SU campus.  Our working group is presently working on coverage mapping and initial sensor deployment. The LoRaWAN gateways are part of “The Things Network” (see for more information) and provide capabilities to capture data from sensors across SU, the city of Syracuse, and beyond, given the deployment of Things Network gateways in many US and international cities.

Several Raspberry Pi 3 nodes with a customized sensor board will be deployed in the building of the School of Information Studies (Hinds Hall) enabling the building to act as a “living lab” for IoT projects. The data captured by these nodes will be sent to our data processing cluster.  Beyond its use in IoT experiments, we anticipate using the data in several courses at the iSchool related to data analytics and visualization.
