Robin Ohs
PhD Student & Developer
Researching Space Networks and Sustainability in Computing
๐ Hi, I'm Robin!
I am a Ph.D. student at the Dependable Systems and Software chair at Saarland University in Germany, under Dr.-Ing. Andreas Schmidt and Prof. Dr. Holger Hermanns.
With a passion for web development and space technologies, my journey began with a Bachelor's in Cybersecurity, where I focused on generating automated software tests for Android applications. Between my bachelor's and master's, I worked on a scrum team at the German Air Force, gaining experience with agile software development, continuous integration, and tools like Jira and Confluence.
During my master's, I developed a satellite energy simulator, contributed to a Rust library for resource-aware applications, and implemented a system daemon for carbon-aware operating systems. Now, as a Ph.D. student, I research space networks and sustainable computing.

๐ท My Projects
2024
carbond is an operating-system daemon designed for carbon awareness. It monitors and manages the carbon footprint of computing systems by tracking energy consumption and providing insights into the environmental impact of software operations. The daemon provides the grid intensity for the system by considering common physical inefficiencies such as the PSU. Additionally, it has the capability to track the carbon intensity of a built-in internal battery. This project is part of an effort to promote sustainable and eco-friendly computing practices.

FLoRaSat (Framework for LoRa-based Satellite networks) is a comprehensive framework designed for simulating LoRa-based satellite networks. Built on the Omnet++ discrete-event simulator, FLoRaSat enables detailed end-to-end simulations for satellite Internet of Things (IoT) applications. The framework adapts LoRa and LoRaWAN protocols specifically for space communications, allowing researchers and developers to analyze and optimize satellite network performance. Additionally, it has the capability to research routing algorithms for Low Earth Orbit (LEO) satellite constellations, making it a versatile tool for studying and enhancing satellite IoT systems.
totp-kt is a Kotlin library designed for implementing HOTP and TOTP (time-based one-time passwords) in your applications. It offers support for generating and validating 2-factor authentication codes, creating recovery codes, and generating secure random secrets. The library is useful for enhancing the security of your applications by providing a reliable method for two-factor authentication..
