Communication networks are always built to serve the people for their given needs. Currently, communication networks need to provide low latency, resilience, security and not just bare throughput. Our research philosophy can be described as “Theory that matters!”. Theoretical fundamental research results are tested using different approaches such as simulations, software in the loop, hardware in the loop, and testbeds. Importantly, implementations are not merely used to show feasibility, but rather to derive further relevant research questions by exposing theory to the real world. We apply this philosophy to all our research areas.
