Spectrum sensing on emergency radio spectrum management system

Big natural or manmade disasters damage infrastructure and cause severe effect on civilizations. Existing telecommunication infrastructure goes down as well as power, water etc. Quick and effective rescue operation requires a collaborative communication infrastructure for the rescue teams. Emergency spectrum usage of the rescue teams is one of the major issues in such scenario. Different teams interfere with each other for lack of collaboration and infrastructure limitations. This study designed and developed a cognitive wireless sensor network that collects and forms a database of the active emitters on the disaster scene. This paper focuses especially on a distributed spectrum sensing scheme for the emergency radios.
