Survivable virtual network embedding has been an hot issue in network virtualization research. Previous researches mainly use protection mechanisms to deal with this problem, which may bring excessive consumption to the substrate network. In this paper, the survivable virtual network embedding problem is considered as an integer linear programming model. We(More)
To deal with the existence of malicious secondary users bring damage to the performance of cooperative spectrum sensing, a trust game model named FRTrust is proposed. In FRTrust, the reputation status is used to describe the performance of a secondary user in cooperative spectrum sensing process. It encourages secondary users to choose positive and honest(More)
