Sensor network communication

Contact: Geert Leus

Communication for measurements and control; underwater communication; localization and clock synchronization.
Distributed sensor systems consist of a large number of nodes with only local communication capabilities. Challenges include localization of the nodes, low-power communication protocols, and distributed estimation algorithms, where local estimates are combined to form global parameters estimates.

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.
