Performance of DTLS with Connection ID in Narrowband IoT Networks

Explore the performance implications of implementing DTLS with Connection ID extension in Narrowband-IoT networks through this 20-minute conference talk from RIOT Summit 2025. Learn how Connection ID maintains session continuity when IP addresses or ports change in constrained networks, eliminating the need for new DTLS handshakes that would otherwise be required with each IP address change. Discover detailed performance analysis including handshake duration measurements and current consumption evaluations conducted on embedded hardware such as the Nordic nRF9160 DK. Examine the practical benefits of this approach for secure communication in cellular NB-IoT environments through both theoretical analysis and hands-on performance data. Watch a live demonstration that measures the real-world impact of IP address changes on session continuity and resource usage in constrained network environments. Gain insights from research conducted as part of a Computer Science bachelor's thesis at Hochschule Bonn-Rhein-Sieg, focusing on secure and efficient communication protocols specifically designed for resource-constrained IoT deployments.
