We propose two novel hybrid optimization methods\u2014Hybrid Grey Wolf Optimization with Particle Swarm Optimization (HGWOPSO) and Hybrid World Cup Optimization with Harris Hawks Optimization (HWCOAHHO)\u2014designed to symmetrically balance global exploration and local exploitation, thereby enhancing model training and adaptation in IoT environments. These methods leverage complementary search behaviors, where symmetry between global and local search processes enhances convergence speed and detection accuracy. The proposed approaches are validated using real-world IoT datasets, demonstrating significant improvements in anomaly detection accuracy, scalability, and adaptability compared to state-of-the-art techniques. Specifically, HGWOPSO combines the symmetrical hierarchy-driven leadership of Grey Wolves with the velocity updates of Particle Swarm Optimization, while HWCOAHHO synergizes the dynamic exploration strategies of Harris Hawks with the competition-driven optimization of the World Cup algorithm, ensuring balanced search and decision-making processes. Performance evaluation using benchmark functions and real-world IoT network data highlights superior accuracy, precision, recall, and F1 score compared to traditional methods. To further enhance decision-making, a Multi-Criteria Decision-Making (MCDM) framework incorporating the Analytic Hierarchy Process (AHP) and TOPSIS is employed to symmetrically evaluate and rank the proposed methods. Results indicate that HWCOAHHO achieves the most optimal balance between accuracy and precision, followed closely by HGWOPSO, while traditional methods like FFNNs and MLPs show lower effectiveness in real-time anomaly detection. The symmetry-driven approach of these hybrid algorithms ensures robust, adaptive, and scalable monitoring solutions for IoT networks characterized by dynamic traffic patterns and evolving anomalies, thus ensuring real-time network stability and data integrity. The findings have substantial implications for smart cities, industrial automation, and healthcare IoT applications, where symmetrical optimization between detection performance and computational efficiency is crucial for ensuring optimal and reliable network monitoring. This work lays the groundwork for further research on hybrid optimization techniques and deep learning, emphasizing the role of symmetry in enhancing the efficiency and resilience of IoT network monitoring systems.<\/jats:p>","DOI":"10.3390\/sym17030388","type":"journal-article","created":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T09:01:33Z","timestamp":1741078893000},"page":"388","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Advanced Deep Learning Models for Improved IoT Network Monitoring Using Hybrid Optimization and MCDM Techniques"],"prefix":"10.3390","volume":"17","author":[{"given":"Mays","family":"Qasim Jebur Al-Zaidawi","sequence":"first","affiliation":[{"name":"Department of Electrical-Electronics Engineering, Faculty of Engineering and Architecture, Alt\u0131nba\u015f University, Istanbul 34000, T\u00fcrkiye"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0299-9076","authenticated-orcid":false,"given":"Mesut","family":"\u00c7evik","sequence":"additional","affiliation":[{"name":"Department of Electrical-Electronics Engineering, Faculty of Engineering and Architecture, Alt\u0131nba\u015f University, Istanbul 34000, T\u00fcrkiye"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"429","DOI":"10.1016\/j.dt.2023.02.007","article-title":"Distributed Multicircular Circumnavigation Control for UAVs with Desired Angular Spacing","volume":"31","author":"Li","year":"2024","journal-title":"Def.
