The increased use of ISM frequencies (Industrial, Scientific and Medical) has caused interference problems and lack of availability of resources for wireless networks. Cognitive Radios (CR) emerged as an alternative to reduce interferences and intelligently use the spectrum. Several protocols have been developed to solve these problems, however, they focus on spectrum sensing or spectrum decision. This paper presents ISCRa (Intelligent Sensing for Cognitive Radios), a MAC protocol based on artificial neural networks and data obtained from regulatory agencies. Results demonstrate that ISCRa obtained higher delivery rate in high traffic when compared to CogMAC and AHP protocols, while maintaining the latency.
