Unlike traditional artificial intelligence (AI) technologies, GAI and LLMs possess powerful self-learning, data-modeling, and context-aware capabilities. Specifically, GAI can extract deep features and semantic information from large amounts of data, which allows it to make intelligent predictions and optimize processes for a flexible response to changes in complex environments. Moreover, by simulating network behaviors under different scenarios and generating new data points, GAI can optimize network architecture and expand training datasets to improve model robustness and generalization. Additionally, LLMs can rapidly adapt to diverse tasks through a few-shot learning. Furthermore, they can incorporate techniques such as retrieval-augmented generation (RAG), thereby strengthening their capacity to handle complex text-based tasks and achieve precise information generation and intelligent interaction.","PeriodicalId":100628,"journal":{"name":"IEEE Networking Letters","volume":"7 3","pages":"157-160"},"PeriodicalIF":0.0,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11206727","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145352045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Network slicing enables the logical segmentation of an infrastructure to meet specific Quality of Service (QoS) requirements posed by applications, but factors such as fluctuating traffic, user mobility, and cross-slice interference, pose challenges towards proactive resource allocation. Traditional methods struggle with these factors, leading to inefficiencies. Therefore, this letter explores the concept of an AI-driven network performance prediction and resource allocation framework using Temporal Graph Networks (TGNs). By integrating TGN with the NS-3 simulator, the work in this letter demonstrates an efficient approach to predict network throughput.

In this letter, we present an efficient vision transformer (ViT)-based framework to directly capture correlations among terrain, interference, and coverage characteristics, bypassing the conventional path loss modeling. Experiments on urban scenarios demonstrate that ViT achieves the lowest prediction error against the ray tracing benchmark, outperforming COST 231 by more than 10% and exhibiting lower error than convolutional neural network (CNN)-based models, including AlexNet, ResNet, and a recent CNN for propagation prediction. Moreover, it also reduces computation time by up to two orders of magnitude compared to propagation models.
