In a cognitive radio network, selfish secondary users may not voluntarily contribute to desired cooperative sensing. We design the first fully distributed scheme to incentivize participation of nodes in cooperative sensing, by connecting sensing and spectrum allocation, and offering incentive from latter to the former. Secondary users that are more active and report more accurate sensing values will...
Cognitive radio techniques represent an emerging approach for mitigating the spectrum scarcity problem in wireless communications. Cooperative sensing is an effective solution to improve sensing accuracy and robustness in the presence of fading and shadowing that make individual sensing less reliable. However, when an adversary can corrupt some nodes in the network, the effectiveness of cooperative...
