A contract-based cooperative spectrum sharing model in cognitive radio network by Guangqiang SHI, Ying LIU, Xiaomin MU

“…A contract-based cooperative spectrum sharing model in cognitive radio network was proposed.In this model,secondary user offers relay service for primary user when primary user's channel is poor.In return,when primary user's channel is good,secondary user can use spectrum with the underlay mode under the condition that the interference is limited.Contract theory in economics was introduced to this framework,the problem of collaboration between the primary and secondary users was modeled as a contract design problem,and the effectiveness function of evaluate primary and secondary users on contract revenue was set up.And the differential evolution algorithm was used to solve the problem.Finally,in different circumstances,primary user collaboration and un-collaboration were contrasted.The results showed that the main users under the condition of no additional input spectrum,not only save the sending power,but also effectively improve the data transfer rate,and improve the energy efficiency and spectrum efficiency.…”

Secure Cooperative Spectrum Sensing for the Cognitive Radio Network Using Nonuniform Reliability by Muhammad Usman, Insoo Koo

“…Both reliable detection of the primary signal in a noisy and fading environment and nullifying the effect of unauthorized users are important tasks in cognitive radio networks. To address these issues, we consider a cooperative spectrum sensing approach where each user is assigned nonuniform reliability based on the sensing performance. …”

Dynamic spectrum access mechanism based on graphical evolutionary game in radio networks by Fang-wei LI, Ying-hui YUAN, Jiang ZHU

“…In order to realize efficient data transmission for users in radio networks,a dynamic spectrum access mechanism based on graphical evolutionary game was proposed for the bounded rationality characteristic of users,while graphical game can better reflect the actual game relationship among users.Meanwhile,a dynamic spectrum access algorithm and corresponding dynamic equation were designed for the mechanism to reduce the complexity of the game,and could converge to Nash equilibrium with faster speed and obtain higher system throughput and utility.Theoretical analysis showed that the dynamic equation was globally asymptotically stable,which illustrated that when user deviated because of bounded rationality and it was still able to guarantee faster converge and fewer performance deviation.Simulation comparison verifies the superiority above.…”
