LEO multi-service routing algorithm based on multi-objective decision making by Li YANG, Jing SUN, Cheng-sheng PAN, Qi-jie ZOU

“…In low earth orbit(LEO) satellite networks,in view of the unbalanced link resource,it's difficult to meet differentiated quality of service(QoS) requirements and easily lead to reduce the efficiency of the whole network.A routing algorithm based on multi-objective decision making was proposed which defined LEO satellite network transmission service as the delay sensitive,sensitive bandwidth and reliability sensitive three categories.It used the eigenvector method to calculate service weights,and used the consistency ratio to determine whether it can be accepted.Based on the multi-objective decision making theory,it combined with the actual state of satellite network nodes and links and the specific requirements of the business,calculating the path that meets the QoS requirements of the service,so as to realize the LEO satellite network multi objective dynamic routing optimization.Established simulation platform based on the iridium network system simulated network delay,the uncertain characteristics like the residual bandwidth and packet error rate,route planning for the randomly generated three classes of business.The simulation results show that,the algorithm not only satisfies the QoS constrain while balancing the traffic load of the satellite link effectively,but also improves the performance on the throughput.…”

Water Quality Prediction Based on Exponential Smoothing-Gray Model for Kuncheng Lake by RONG Jie, ZHANG Fengtai

“…Predicting the development trend of surface water environmental quality is an important basis for managing the current water environment as it provides an important reference for water environment planning,evaluation,and management.The water quality data total phosphorus of the central section of Kuncheng Lake for 2012—2021 are leveraged to build an exponential smoothing-grey prediction GM (1, 1) model.The results show that after smoothing,the model can filter out some short-term irregular changes in the data,that is,small-scale fluctuations in water quality,to reduce the randomness of water quality data so that the data can better reflect the overall trend.The model output value (simulated value) fits well with the original sequence (smoothed value).After the model passes the test,the total phosphorus that restricts the section from reaching the class Ⅲ water standard is predicted.The results show that room for further improvement remains for the central section of the lake to reach the class Ⅲ lake water standard during the 14th Five-Year Plan period.Close attention should continue to be paid to improving the water quality of the section to reach the standard,and sustained efforts should be made to strengthen the treatment and ecological restoration of the lake.…”
