Existing works typically treat medical IoT sensing, smart-city anomaly detection, or edge-cloud offloading as isolated problems, thereby failing to support integrated sensing scenarios in shared smart environments. This paper introduces a Hybrid Edge\u2013Cloud Intelligence Framework (HECIF) for reliable sensing and data fusion in smart healthcare and urban IoT environments. HECIF introduces modality-specific feature extraction, adaptive offloading to the edge cloud, an attention mechanism for multimodal fusion, and a reliability-weighted decision layer that incorporates sensor quality and transmission delay. The framework was tested on three publicly available datasets: the Multi-Sensor Medical IoT dataset for physiological signal classification, the UrbanIoT Anomaly dataset for urban anomaly detection, and the IoT Sensor Cloud Data Transmission dataset for offloading decision modeling, all from Kaggle. It achieved a 92.1% accuracy, 91.3% F1-score, 93.8% AUC, and 0.821 Matthews correlation coefficient in a simulated edge cloud environment, outperforming the baselines (logistic regression, random forest, XGBoost, MLP, CNN\/LSTM). The framework also reduced the mean inference time to 29 ms, down from 142 ms in the cloud-only configuration, while achieving a throughput of 1150 samples per second. The results show that reliability-aware edge cloud fusion is feasible for cross-domain IoT sensing with a simulated edge cloud. However, physical device validation and real-world IoT network validation are still required before practical deployment.<\/jats:p>","DOI":"10.3390\/s26134211","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T07:59:47Z","timestamp":1783065587000},"page":"4211","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Hybrid Edge\u2013Cloud Intelligence Framework for Reliable AI-Driven Sensing and Data Fusion in Smart Healthcare and Urban Environments"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5187-3184","authenticated-orcid":false,"given":"Fahd M.","family":"Aldosari","sequence":"first","affiliation":[{"name":"Department of Computer and Networks Engineering, Computing College, Umm Al-Qura University, Makkah 24382, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,3]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"The Internet of Things","volume":"Volume 1","author":"Evans","year":"2011","journal-title":"How the Next Evolution of the Internet is Changing Everything"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"228","DOI":"10.1177\/01655515231188338","article-title":"Internet of Things adoption and use in academic libraries: A review and directions for future research","volume":"52","author":"Asim","year":"2026","journal-title":"J.
