A Focused, Context-Sensitive Approach to Monitoring
We address two issues which arise in the task of detecting anomalous behavior in complex systems with numerous sensor channels: how to adjust alarm thresholds dynamically, within ...

Power allocation optimization in OFDM-based cognitive radios based on sensing information
Owing to the non-zero probability of the missed detection and false alarm of active primary transmission, a certain degree of performance degradation of the primary user (PU) from...
