Intelligent On-demand Routing Protocol for Ad Hoc Network
Yongfei Ye,Xinghua Sun,Minghe Liu,Jing Mi,Ting Yan,Lihua Ding 한국정보처리학회 2020 Journal of information processing systems Vol.16 No.5
Ad hoc networks play an important role in mobile communications, and the performance of nodes has asignificant impact on the choice of communication links. To ensure efficient and secure data forwarding anddelivery, an intelligent routing protocol (IAODV) based on learning method is constructed. Five attributes ofnode energy, rate, credit value, computing power and transmission distance are taken as the basis ofsegmentation. By learning the selected samples and calculating the information gain of each attribute, thedecision tree of routing node is constructed, and the rules of routing node selection are determined. IAODValgorithm realizes the adaptive evaluation and classification of network nodes, so as to determine the optimaltransmission path from the source node to the destination node. The simulation results verify the feasibility,effectiveness and security of IAODV.

Research and Implementation of U-Learning System Based on Experience API
Xinghua Sun,Yongfei Ye,Jie Yang,Li Hao,Lihua Ding,Haomin Song 한국정보처리학회 2020 Journal of information processing systems Vol.16 No.3
Experience API provides a learner-centered model for learning data collection and learning process recording. In particular, it can record learning data from multiple data sources. Therefore, Experience API provides verygood support for ubiquitous learning. In this paper, we put forward the architecture of ubiquitous learningsystem and the method of reading the learning record from the ubiquitous learning system. We analyze students’learning behavior from two aspects: horizontal and vertical, and give the analysis results. The system canprovide personalized suggestions for learners according to the results of learning analysis. According to thefeedback from learners, we can see that this u-learning system can greatly improve learning interest and qualityof learners.

Research on the Application of Load Balancing in Educational Administration System
Junrui Han,Yongfei Ye 한국정보처리학회 2023 Journal of information processing systems Vol.19 No.5
Load balancing plays a crucial role in ensuring the stable operation of information management systems duringperiods of high user access requests; therefore, load balancing approaches should be reasonably selected. Moreover, appropriate load balancing techniques could also result in an appropriate allocation of systemresources, improved system service, and economic benefits. Nginx is one of the most widely used loadbalancingsoftware packages, and its deployment is representative of load-balancing application research. Thisstudy introduces Nginx into an educational administration system, builds a server cluster, and compares andsets the optimal cluster working strategy based on the characteristics of the system, Furthermore, it increasesthe stability of the system when user access is highly concurrent and uses the Nginx reverse proxy servicefunction to improve the cluster’s ability to resist illegal attacks. Finally, through concurrent access verification,the system cluster construction becomes stable and reliable, which significantly improves the performance ofthe information system service. This research could inform the selection and application of load-balancingsoftware in information system services.
