Detecting Anomalous Spectrum Usage in Dynamic Spectrum Access Networks
Dynamic spectrum access has been proposed as a means to share scarce radio resources, and requires devices to follow protocols that access spectrum resources in a proper, disciplined manner. For a cognitive radio network to achieve this goal, spectrum policies and the ability to enforce them are necessary. Detection of an unauthorized (anomalous) usage is one of the critical issues in spectrum etiquette enforcement. In this paper, the authors present a network structure for dynamic spectrum access and formulate the anomalous usage detection problem using statistical significance testing.
