Analysis and Optimization in Wireless Sensor Network Aided Cognitive Radio Systems
Vijayandran, Luxmiram (Doktoravhandlinger ved NTNU, 1503-8181; 2012:225, Doctoral thesis, 2012)To enhance cognitive radio (CR) technology, this thesis focuses on the wireless sensor network aided cognitive radio scenario. The main role of the wireless sensor network (WSN) in practice is to overcome the inherent ... -
Increasing sum-rate in large-scale cognitive radio networks by centralized power and spectrum allocation
Vijayandran, Luxmiram; Byun, Sang-Soon; Øien, Geir Egil; Ekman, Torbjörn (Journal article; Peer reviewed, 2012)We revisit the widely investigated problem of maximizing the centralized sum-rate capacity in a cognitive radio network. We consider an interference-limited multi-user multi-channel environment, with a transmit sum-power ...
