Exploiting Radio Correlation and Reliability Information in Collaborative Spectrum Sensing

Abstract

Prior research has demonstrated that using radio correlation or radio reliability information can lead to more efficient collaborative spectrum sensing. However, the joint consideration of this position-dependent information is at present underdeveloped. This paper presents a novel collaborative spectrum sensing algorithm in which both radio correlation and reliability information are jointly considered. Accompanying performance analysis demonstrates that the proposed algorithm outperforms algorithms in which only one, or neither, of these position-dependent effects are considered.
