The identification of the modulation type of the intercepted frequency hopping signals in electronic information warfare is very important for the subsequent study and processing of the signals. In this paper, the Transformer algorithm is introduced into the field of modulation recognition, and the average recognition rate is 1.82% higher than ResNet50 by experimental comparison. For the interference of pre-processing cropping and patch merging in Swin Transformer on the clarity of time-frequency images, this paper adds Fast-NLM denoising to improve the average recognition rate by 0.8%. In addition, for the problem of attention scattering in Swin Transformer, this paper adopts a variable attention model, and the key sampling points around the reference points on the feature map are moved closer to the feature area by the calculation of offset, so that the feature representation can be better obtained. The experimental results show that the recognition rate of the improved model is 2.35% higher than that of the original model, the perception ability of some modulated signals is enhanced, and the addition of denoising can improve another 0.840%.","PeriodicalId":334790,"journal":{"name":"2023 3rd International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132577556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach thoroughly takes into account link traffic information, node degrees, and node costs to identify the IP network nodes that need replacement. The newly introduced link optimization model achieves energy savings by dynamically turning off high link utilization links. The Nlucs algorithm not only avoids the issue of lengthy iterative solution times found in existing genetic algorithms, but also ensures a balance between network performance and energy-saving effects. The Nlucs algorithm was compared experimentally with other classic hybrid SDN network energy-saving algorithms. The results show that, whether in terms of energy-saving efficiency or stability, the Nlucs algorithm demonstrates significant advantages, especially in large-scale networks where it can save energy more effectively and reduce network operation costs. This research provides a new direction and implementation plan for device selection and energy-saving strategies in hybrid SDN networks.","PeriodicalId":334790,"journal":{"name":"2023 3rd International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"530 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123037802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traffic planning is the fundamental measure to solve the existing traffic problems. Many urban road congestion problems are not caused by inadequate traffic organization and management, but by defects at the planning level. The study area of this paper is located on Zhongshan Road in Dalian, which spans three administrative districts and connects financial, cultural, political, and commercial centers into one. The data used are from the 2019 survey of relevant personnel, the OD inversion using TransCAD, the occurrence and attraction of traffic, the traffic distribution, and finally the traffic flow prediction. In the traffic distribution prediction for 2022, 2024 and 2026 respectively using exponential growth method and gravity model method.
