Cooperative spectrum sensing for geo-location databases

Spectrum sensing techniques are the key components for identifying and exploiting unused radio spectrum resources in the perspective of the cognitive radio paradigm. Based on the centralized cooperative sensing techniques, vast generalized databases named geo-location databases (GL-DB) can be deployed in order to centralize sensing and general radio spectrum data for the benefit of secondary cognitive radio users. The authors propose a hybrid conceptual application that involves spectrum sensing and a Human Network Interaction (HNI) model with the purpose of perceptually representing, in an immersive way, the available GL-DB information from a specific location for a natural user perception and interaction with the area of interest. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
