Energy-Efficient in Cognitive Radio network by optimizing sensing and transmission time

This essay examines the challenge of developing cooperative spectrum sensing methods that use little energy (CSS). After it was shown that a single sensor device is insufficient for accurate readings, the idea of a network of sensors working together to collect data was introduced, albeit at a significant cost in terms of overhead. Thus, there has been an increase in interest in research into energy-efficient cooperative schemes, leading to the development of several energy-efficient cooperative algorithm approaches. In this work, we make an effort to classify potential future developments in energy-efficient CSS and provide a small selection of works that introduce novel concepts to an energy-efficient CSS algorithm.
