This is particularly evident during intensive event coverage, where Sports Live imposes significant processing pressures on real-time delivery and user experience within these networks. To address these challenges, this paper introduces a fast video distribution system for sports content that leverages the synergy between cloud computing and edge computing. By deploying edge devices to distribute sports video content, the system adeptly manages the sparsity and randomness of user requests and behaviors in edge networks. Focusing on the characteristics of smaller user groups allows for a more accurate representation of the broader audience, optimizing performance at a lower operational cost. Both cloud and edge computing devices are equipped with storage capabilities to cache sports video content, thereby implementing a dual caching strategy. This approach offers two primary benefits: it conserves core network bandwidth and minimizes latency for users accessing content. Given the escalating demands for low-latency and high-bandwidth multimedia sports video content—such as real-time interactive sports broadcasts and UHD sports videos—the proposed cloud–edge collaborative caching mechanism effectively meets these stringent requirements. The system ensures seamless and efficient delivery, enhancing both user satisfaction and operational efficiency in dynamic sports streaming environments.</p>\u0000 </div>","PeriodicalId":100725,"journal":{"name":"Internet Technology Letters","volume":"8 4","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100801","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}

In this paper, we present a Contrary Index Spectrum Assignment with Shared Path Protection (CISA-SPP) strategy for assigning primary and backup routes in a mixed grid optical network. In the proposed CISA approach, spectrum allocation for the primary route is conducted in increasing index order, while for backup routes, the spectrum is allocated in decreasing index order. This reversal of indexing reduces spectrum contention with existing connections and enhances resource sharing for backup routes. We compare the CISA-SPP strategy with three traditional survivable strategies: Dedicated Path Protection (DPP), Partial Path Protection (PPP), and Shared Path Protection (SPP). The results demonstrate that the proposed strategy achieves lower bandwidth blocking probability, more efficient resource allocation for backup routes, and improved resources overbuild ratio compared to the existing strategies.</p>\u0000 </div>","PeriodicalId":100725,"journal":{"name":"Internet Technology Letters","volume":"8 3","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919641","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}

Wavelet-based denoising lacks adaptivity and can be affected by the wavelet function, the number of decomposition layers, and the threshold function. Although the denoising method based on deep learning has achieved a good denoising effect, it fails to integrate with the physical model and lacks certain theoretical support. To address these problems, this paper proposes a deep fusion network for signal denoising, named WDNet, based on wavelet denoising theory and deep learning techniques. We initialize the tap coefficients of the wavelet decomposition and reconstruction filters as learnable parameter matrices and use the soft threshold function as the activation function so as to realize the decomposition, thresholding, and reconstruction of the signal. The filter and threshold are adjusted adaptively by backpropagation to achieve optimal signal denoising. Simulation results demonstrate that our model achieves a higher signal-to-noise ratio (SNR) gain and lower root mean square error (RMSE) compared to other methods.

UOWC systems have gained significant attention for their high data rate capabilities in underwater environments. This paper presents a comprehensive performance analysis of a mode division multiplexing (MDM)-based UOWC system employing four distinct Hermite-Gaussian (HG) modes, each supporting independent 10 Gbps data streams.

Advanced methods of neural networks and optimization are gradually being applied in order to solve these difficulties. The heterogeneous nature of 5G-and-beyond networks introduces severe multipath fading, high mobility, and interference, complicating accurate Channel State Information (CSI) estimation. Existing techniques are sometimes difficult to compute efficiently while at the same time providing a precise estimation of interference in such scenarios. This research develops an Optimized Neuro-Adaptive Twin Pulse-Coupled Estimators for Efficient Channel Estimation in Heterogeneous 5G-and-Beyond MIMO-OFDM Communication Systems (STEB-Twin-APCNet) to improve the channel estimation by integrating Twin Adaptive Pulse Coupled Network with Sooty Tern Evolutionary Boost optimization. The objective of this study is to design and optimize a neuro-adaptive channel estimator capable of real-time CSI acquisition with high accuracy and minimal complexity in diverse 5G environments. To test the model in different channel scenarios, MATLAB simulations were run with the help of deep learning and 5G toolboxes.
