Collaborative spectrum sensing among secondary users (SUs) in cognitive networks is shown to yield a signific ant performance improvement. However, there exists an inheren t trade off between the gains in terms of probability of detect ion of the primary user (PU) and the costs in terms of false alarm probability. In this paper, we study the impact of this trade off on the topology and the dynamics of a network of SUs seeking to reduce the interference on the PU through collaborative sen sing… CONTINUE READING
