Based on the TNC architecture, using a trusted network of repair techniques in the trusted network access scenario does not meet the requirements of integrity verification solution for end users. Put forward a credible fix the overall network design, reliable model restoration and repair services, network workflow. The system is in need of restoration to provide safe and reliable repair end-user data transmission, providing a humane, reasonable repair services to ensure the credibility of fixed network and the isolation effect of the terminal to be repaired and strengthened the security of fixed server. Realized the classification of various types of repair resources management, restoration of resources in ensuring the transfer of fast, reliable, based on the performance with a certain extension.

In cognitive radio (CR) networks, cooperation can greatly improve the performance of spectrum sensing. In this paper, we propose a novel cooperative spectrum sensing (CSS) frame structure in which CR users conduct spectrum sensing and data transmission concurrently over two different parts of the primary user (PU) spectrum band. Energy detection sensing scheme is used to prove that there exists an optimal sensing bandwidth which yields the highest throughput for the CR network. Thus, we focus on the optimal sensing settings of the proposed sensing scheme in order to maximize the throughput of the CR network under the conditions of sufficient protection to PUs and required bandwidth for potential CR user data transmission. Some algorithms are also derived to jointly optimize the sensing bandwidth and the final decision threshold. Our simulation results show that optimizing the sensing bandwidth and the final decision threshold together will further increase the throughput of the CR network as compared to that which only optimizes the sensing bandwidth or the final decision threshold.

The data distribution platform is the ground information center of the relay satellite system to realize the data relay ability. With the increasing demand of the user data transmission, the data transmission ability of the relay satellite system is increasing. The increasing data transmission ability of the satellite puts forward higher requirements for the data distribution ability of the ground distribution platform. In this paper, the technology of data acquisition and data exchange based on the kernel state of the domestic operating system is studied. The design method of data distribution platform based on the kernel state programming of the domestic operating system is proposed. The simulation test environment is built to verify the effectiveness of the method, which can greatly improve the data processing ability of a single data distribution device, significantly reduce the scale of data distribution device, it provides strong technical support for building a new model of intensive and efficient data distribution.
