Korean Electronics Technology Institute (KETI) hosted an online hackathon in partnership with TTA and ETSI and supported by the Ministry of Science and ICT South Korea. Participants included students from various universities, interested developers from startups and small medium enterprises.
The evaluation criteria for this hackathon was based on the innovative use of the onem2m, IoT, sensors to generate a useful solution. oneM2M is the global standards initiative that covers requirements, architecture, API specifications, security solutions and interoperability for Machine-to-Machine and IoT technologies.
The last week of November began with an awards ceremony to announce the results of an 8 week international hackathon involving 12 university teams across the world. Out of which two teams from Smart City Living Lab, IIITH participated in this hackathon.
– Team Athena: Vaibhav – Team lead, Prashant, Rakesh and Sudha
– Team Echo: Leo -Team lead, Noopur, Ushasri and Nagesh
Of the two teams, Team Athena was awarded Best Technology Award in Telecommunication category with the project title Street lights Automation using oneM2M. The Director General of Korea’s Ministry of Science and ICT, Mr. Jeongsam Kim congratulated this year’s participants who continue a tradition that dates to the first, oneM2M International Hackathon of 2022. The primary goal of this project was to deploy smart streetlight control across cities to save the workload and energy usage by using IoT and Wi-SUN technology.

The Subscription (SUB), Access Control Policy (ACP), Internetworking Proxy Entity (IPE) features of oneM2M had been extensively used for this deployment. Wi-SUN RF-mesh was used for the data connectivity and a border router at the final leg to get the data to the oneM2M cloud using WiFi. The light control was done based on the light intensity measured using luminosity sensor.
Wi-SUN RF-mesh is used for its unique feature of being a self healing network, deployment for a longer reachability and less infra requirement. It is suitable for low bandwidth IoT data with sufficient data rates. It is from Silicon Labs which is a corporate funding partner of Smart City Living Lab.
The status of each streetlight can be monitored on the centralized dashboard. The customizable dashboard focuses on general system status, the notification engine alerts of important events, temperature, humidity, RSSI, Latency and the map interface helps deep dive into details. Manual commands allow complete control of individual streetlights. A DO-DAG network display to show the live mesh network connectivity is also demonstrated.
A hardware dashboard was also created as a part of the project, to show a live mini replica of the status of streetlights from the lab. This helped determine if any node has not been updated due to lack of acknowledgement from the mesh network.
The Winning Team members were all from Smart city living lab.
