Sensor network communication
Contact: Geert Leus
In sensor networks, we shift from centralized communication networks to distributed self-organizing networks where nodes adapt their procedures (related to spectrum utilization, sensing, information processing, and localization) based on only local information. To develop large self-organizing networks we need cognitive radio devices that are capable of sensing the radio spectrum and adapt accordingly. We further require energy efficient distributed information processing and localization algorithms for large sensor networks. The mathematical tools we want to build on are compressed sampling, convex optimization, game theory, and linear algebra.
