In smart cities, farmers rely on accurate, up-to-date weather information to make informed decisions. Increasing climate variability has made temperature prediction more challenging than ever. Deep learning has recently emerged as a powerful approach for weather forecasting due to its superior performance over conventional methods and its ability to extract and classify features within a single architecture. This study explores the use of deep Convolutional Neural Network (CNN) models, specifically Visual Geometry Group 16 (VGG16) and MobileNet, with transfer learning for intelligent weather monitoring. The combination of MobileNet and VGG16 leverages transfer learning for accuracy-driven and efficient operations. MobileNet is optimised for mobile and edge devices by delivering high-performance results with lower computational and energy costs, while the deep architecture of VGG16 effectively identifies complex visual features across multiple tasks. Trained on a dataset of weather images, the proposed models accurately detect and classify different weather conditions, enabling farmers to make improved field decisions. Experimental results demonstrate strong performance, with VGG16 achieving 96.95% accuracy and MobileNet achieving 96.19% accuracy.</p>","PeriodicalId":34740,"journal":{"name":"IET Smart Cities","volume":"8 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/smc2.70026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147585076","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}

Traditional systems often rely on static and predefined boundaries that fail to respond to rapidly changing environments such as construction sites, public gatherings or emergency situations. This paper introduces a novel deep learning-driven framework using ground-plane homography for real-time proactive intrusion prediction within these dynamically restricted zones (DRZs). Our method first employs deep learning to accurately detect and localise physical restriction markers (e.g., traffic cones). We then utilise ground-plane homography estimation to accurately map these markers into two-dimensional ground-plane perspective, precisely defining the spatial boundaries of the DRZ in real-time. After the reactive detection of restriction markers region, intrusion prediction is achieved through sophisticated human trajectory analysis and future path extrapolation. By forecasting a person's path and identifying projected future presence within the dynamic ground-plane zone, the system assists proactive alerts and adaptive security responses before an actual violation. To the best of our knowledge, this is the first system capable of predicting intrusions into areas dynamically demarcated by visual restriction markers. The experimental results on real-world surveillance datasets demonstrate the system's effectiveness in identifying the presence of humans in DRZ, validating its potential for deployment in smart cities and critical infrastructure.</p>","PeriodicalId":34740,"journal":{"name":"IET Smart Cities","volume":"8 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/smc2.70024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147299981","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}

Dubai has emerged as an example in the Middle East for adopting smart technologies to enhance urban living, with initiatives ranging from digital governance to intelligent transportation systems. However, the associations between sustainable development and smart city implementation in Dubai is limited. This study aims to investigate the application of the smart city in Dubai, assessing the smart city implementation in terms of sustainable development by applying the system archetypes to assess the implementation of the smart city in Dubai in terms of sustainable development issues. After the identification of the system archetypes, it is found that the implementation of smart city initiatives such as e-government and clean transportation are in line with sustainable development issues such as low-carbon emissions and less air pollution. Moreover, this study shows that the structure of the Limits to Growth archetypes has dominated the smart city development in Dubai. This means that the development of Dubai has had critical issues such as persistent traffic congestion and a polluted atmosphere. The findings stress that the smart city application in Dubai is a good exemplar that the smart city can be a sustainable smart city altogether. The second point is although the smart city enables us to achieve a sustainable smart city, the implementation of the smart city should be monitored regularly, especially if reinforcing loops dominate balancing loops as seen in the case of traffic congestion.

Unmanned aerial vehicles (UAVs) can extend this coverage by flying to remote WSN areas and communicating with aggregator nodes (CH-nodes) to retrieve data. Designing UAV-assisted data collection systems therefore requires a careful consideration of both UAV and WSN constraints. This article proposes an energy-efficient approach for UAV-based data collection in IoT/WSNs. The problem is formulated to jointly optimise system cost and energy consumption while accounting for communication power, mission duration, and data importance. The solution proceeds in two steps. First, aggregator nodes are selected using clustering based on residual energy and inter-node distances to minimise system costs. Second, the UAV trajectory is generated using a Lévy flight strategy that follows the positions of the selected aggregators. Although this trajectory may be slightly longer than that produced by a deterministic TSP route, it increases the amount of collected data and prolongs both UAV and WSN lifetime by ensuring timely visits to distant cluster heads.

The ACAMAI pipeline comprises two main stages: (i) training a YOLOv8 object detector to recognise accessibility-related features, such as curb ramps, missing ramps, obstacles and surface problems, in 2D sidewalk images; and (ii) scanning 360° GSV panoramas by extracting multiple perspective views to be analysed by the trained model.

In the panorama scanning stage, using a fine angular iterative step (2°) maximised the <i>recall</i>, reaching 90% for curb ramps and 93% for obstacles in a locally annotated dataset (GSV Panorama Porto Dataset—GSV-PPD).

In the absence of effective collaboration and energy interactions among smart homes, imbalances in the SRMG load profile may occur, risking violations of technical standards. This study introduces a decentralised framework for SRMG that includes diverse smart homes engaged in peer-to-peer (P2P) energy interactions. The framework is designed to minimise variations in the SRMG load profile while also reducing expenses for smart homes, all while ensuring resident comfort through P2P interactions. The home energy management (HEM) system seeks to optimise energy costs by utilising DER capabilities to facilitate P2P interactions and maintain bidirectional communication with the SRMG operator (SRMGO). Continuous data sharing between the SRMGO and HEM systems is crucial for optimising the load profile in a decentralised framework. This enables about a 4.25% reduction in load profile deviations without raising energy costs, showing that decentralised P2P energy interactions improve load management in SRMG and cost stability in smart homes. Simulation results generated using general algebraic modelling system (GAMS) software demonstrate that integrating P2P energy strategies within a decentralised framework can effectively fulfil both the technical requirements of the SRMG and the financial goals of individual smart homes.</p>","PeriodicalId":34740,"journal":{"name":"IET Smart Cities","volume":"7 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/smc2.70019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145522251","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}
