RETRACTED: Next generation mobile edge computing wireless sensor network based Japanese remote interactive practical teaching platform.

The article focuses on the design, implementation, and performance evaluation of a Japanese remote interactive practical teaching platform based on wireless sensor networks (WSN). The platform integrates hardware components—including an ARM S3C4510B microprocessor and optimized interface circuits—with software modules for user roles, interactive teaching, resource management, project release, and security to enhance practical Japanese language education. Performance tests comparing this platform with other methods demonstrated superior I/O performance, higher peak signal-to-noise ratios in video transmission, lower time overhead under increasing user loads, higher signal conversion rates, and closer alignment of automated test scoring with manual grading. While the platform shows promise in improving interaction, scalability, and teaching effectiveness, the study notes that specific Japanese teaching content was not analyzed and suggests further optimization in future work.
