Towards cheat-proof cooperative relay for cognitive radio networks
Haifan Yao, Sheng Zhong · 2011
In cognitive radio networks, cooperative relay is a new technology that can significantly improve spectrum efficiency and system throughput. While the existing protocols for cooperative relay are very interesting and useful, there is a crucial problem that has not been investigated: In reality, selfish users may cheat in cooperative relay, in order to benefit themselves. Here by cheating we mean the behavior of reporting misleading information to other users. Such cheating behavior may harm other users and thus lead to poor system throughput.
