Master's students Cenk Gündogan and Lennart Dührsen won the Cisco Challenge: Best Use of Cisco Technology at the Internet of Things World Europe Hackathon in Berlin. They connected RIOT, the friendly operating system for the IoT, with Tropo, a cloud communications API that makes it easy to build voice & text messaging apps.
