This issue has gained scientific attention due to its complex socio-technical nature. This article examines the architecture of emerging IoT technologies, provides visual illustrations of vulnerabilities in smart environments, and discusses the increase in DDoS attacks related to IoT botnets. Also, we provide a market study of the current IoT and SDN deployments and DDoS landscape that reveals critical gaps between theoretical frameworks and practical adoption. This industry-driven perspective strengthens the motivation for conducting a structured review that aligns emerging academic research with evolving market statistics and deployment challenges. Additionally, we introduce a new IoT DDoS attack taxonomy designed to address protocol-level vulnerabilities in commonly used IoT communication protocols, including MQTT, CoAP, and SSDP. Our taxonomy is comprehensive and innovative, representing the first framework dedicated solely to analyzing IoT-driven DDoS attacks. It offers researchers a better understanding of this problem. By developing this framework, our goal is to help practitioners and researchers identify vulnerabilities, develop mitigation strategies, and strengthen the resilience of IoT environments against DDoS attacks.</div><div>Furthermore, we critically examine state-of-the-art DDoS mitigation techniques within SDN-enabled smart infrastructure. We conduct an incisive evaluation of contemporary DDoS mitigation strategies presented by many researchers, scrutinizing their operational potency, deployment feasibility, and resilience under dynamic, heterogeneous smart surroundings. Our review reveals that while a significant body of research claims to address IoT-based DDoS attacks, the majority of defenses remain centered on conventional network protocols, overlooking the distinct characteristics and vulnerabilities of IoT-specific protocols such as MQTT, CoAP, and SSDP. Building on this study, we identify critical research gaps and highlight novel possibilities for enhancing the resilience of next-generation smart networks against evolving DDoS adversaries.</div></div>","PeriodicalId":48633,"journal":{"name":"Computer Science Review","volume":"60 ","pages":"Article 100903"},"PeriodicalIF":12.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146033304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, it can achieve better capacity, time complexity, and imperceptibility in comparison to the classical system. This survey paper describes various methodologies that have been applied in different steganography domains, such as text steganography, image steganography, audio steganography, and video steganography, and discusses the strengths and weaknesses of each methodology separately.

Since its development, COA has achieved new heights owing its efficacy in solving diverse optimization problems, flexibility and simple procedure. Alike other metaheuristic optimization algorithms, COA based on intelligent metaphor have seen rapid advancements and improvements, however with similar intrinsic weaknesses. The probable reason being inadequate investigations on COA procedure, limitations, statistical evaluation prior to its enhancement. The importance of the current review stems from its in-depth exploration of COA advancements, foundation principles and practical scenarios. This comprehensive review features 91 COA articles for analysing its adaptability and increasing interest in solving non-trivial optimization problems. It precisely explores the COA expansion, researching historical developments and modifications that enhances the algorithm capability in adapting to diverse landscapes of optimization problems. This review investigates the COA articles in terms of year wise publications, including enhancements, chaotic, opposition based learning variants, hybridizations, binary version, multi-objective variants, and different applications. It was shown that Elsevier and Springer have published highest number of COA papers having 54 and 51 counts, respectively. The published articles on classical COA confirm that it is mostly utilized for solving complex optimization problems in the field of electrical engineering (35%), I-o-T (22%) and medical diagnostics (17%) applications. Moreover, it is established that the COA performance has been improved by mostly hybridizing with other metaheuristic algorithms (29%), followed by introducing chaotic mapping (24%) and OBL scheme (15%), respectively. In addition, the present review significantly assesses the COA’s convergence behaviour and statistical performance in comparison to some well-known recent metaheuristic algorithms.

FR, often associated with deep dental decay, can be identified across various dental radiographic modalities, typically appearing as a dark, radiolucent area between the tooth roots. However, accurate interpretation of extraoral and intraoral dental radiographs can be challenging due to the subtle nature of early lesions and variability in image quality. This review explores the transformative potential of Artificial Intelligence (AI)- driven Computer-Aided Diagnosis (CAD) systems, which enhance the detection and analysis of FR, offering clear advantages over traditional methods. AI technologies, particularly Machine Learning (ML) and Deep Learning (DL), enhance critical stages of dental radiographic analysis, including image preprocessing, segmentation, and classification. These advancements enable early identification of subtle radiographic changes, reducing the need for invasive treatments and fostering more proactive treatment planning. The paper provides a comprehensive review of both traditional diagnostic techniques and recent AI-driven innovations, highlighting their impact on improving dental image quality, segmentation precision and classification accuracy. Focusing on powerful AI models such as U-Net, Mask Region-based Convolutional Neural Network (R-CNN), and Vision Transformers (ViTs), along with lightweight deep Convolutional Networks (ConvNets) like MobileNetV2 or EfficientNetV2, the review highlights the potential of these systems to identify dental problems more effectively and facilitate efficient clinical decision-making. Additionally, the paper addresses ongoing challenges, including the need for large-scale validation and multi-modal data integration, and offers actionable insights for researchers and dental practitioners to further leverage AI in pediatric dental care.

Processing these heavy and bursty demands within the autonomy system's power and thermal envelope will require considerable effort in determining which tasks to perform when and in what order. In some cases, offloading workloads to edge or cloud servers creates an opportunity to offload compute, reduce end-to-end latency, and enhance overall responsiveness if workloads are offloaded under strict latency constraints.
