Cooperative and Cognitive Strategies for Interference Management in Wireless Communication Networks (COSIMA)

COSIMAFunding: Spanish Ministry of Education and Science

Principal Investigator: Prof. Baltasar Beferull-Lozano

Topic: Cooperative strategies are those in which several transmitters and/or receivers coordinate between them to improve efficiency or increase their performance inside a wireless network. Cognitive strategies refer to those communication paradigms in which radio terminals adapt their transmission parameters with the aim of not interfering the other transmissions in the network. These parameter adaptations are based on the channel observation or environment spectrum sensing prior to the transmission. The project will develop techniques to perform interference management in a cognitive system based on channel occupancy information obtained from a sensor network. The resulting techniques are expected to provide useable real-world strategies to protect the primary system from harmful interferences. Research in COSIMA will not be limited to a theoretical and algorithmic level but an heterogeneous multiterminal hardware demonstrator will be constructed for the practical evaluation over realistic scenarios of the most promising developed cooperative and cognitive techniques.
