The IMDEA Networks Institute offers one fully funded PhD position in the area of Adaptive Protocols for Decentralized Wireless Networks. The research associate will contribute to the newly established Secure Mobile Systems Group. The main focus of the work will be on adaptable protocols for decentralized wireless/mobile networks and systems. Goal is to enable off-the-shelf systems (such as WiFi-based, LoRa-based, or 5G/6G-based systems) to form emergency networks in case of crisis. These systems shall seamlessly transition between normal operation and crisis mode by switching over into decentralized, island, or direct-mode operation, while maintaining the ability for efficient and secure operation. This allows to leverage local power, compute, and communication abilities even if (part of) the core network is affected by an outage. The research associate will employ methods such as reverse engineering to understand and modify the behavior of off-the-shelf systems. This forms the basis for designing, implementing, and experimentally evaluating adaptive protocols and solutions. The research associate will contribute to building up the newly founded Secure Mobile Systems Group.
