Performance Analysis of Cognitive Radio System Based on Outage Probability of Cognitive Transmission by Haomin Gao, Haifeng Zhao, Xiao Liang, Xiaomin Mu

“…It is an important part to design an optimal spectrum sensing and transmission framework in cognitive radio network.Considering that cognitive data transmission outage had effect on the performance of cognitive radio system,a novel spectrum sensing and transmission model based on the outage probability of cognitive transmission was proposed and the two phases of spectrum sensing and data transmission were jointly optimized.The model was formulated as a nonconvex optimization problem under the constraint of interference to primary user,which maximized the average achievable throughput by the joint optimization of sensing time and data transmission rate and simulated by means of the numerical method.The numerical analysis shows that a better tradeoff can be achieved among the protection of primary user,the throughput of cognitive system and transmission delay when the outage probability is cited and the constraint is satisfied.…”

Bridge monitoring system based on Internet of things technology by Zheng LI, Sheng ZHANG, Luyu ZHANG, Yang ZHANG

“…The Internet of everything is the trend of today’s smart cities.With the rapid development of Internet of things technology,a good opportunity is provided to obtain real-time status information on important infrastructures.Aiming at the problem such as low monitoring efficiency,poor flexibility and rigorous testing results with traditional artificial bridge monitoring methods a bridge monitoring system based on the Internet of things technology was designed.A variety of sensors and cameras were used in the system to collect the data of bridge’s dynamic status in real-time,and the wireless multi-hop network was used to transfer the perception data to the bridge health monitoring cloud platform for further processing and analysis.Real-time monitoring,early warning,analysis and assessment of bridge safety conditions could be realized by the system,and is very important to the bridge safety engineering.…”
