The sensor nodes (SNs) are usually resource constrained such as power source, communication, and computation capacity. In WSN, energy consumption varies depending on the distance between sender and receiver SNs. Communication among SNs having long distance requires significantly additional energy that negatively affects network longevity. To address these issues, WSNs are deployed using multi-hop routing. Using multi-hop routing solves various problems like reduced communication and communication cost but finding an optimal cluster head (CH) and route remain an issue. An optimal CH reduces energy consumption and maintains reliable data transmission throughout the network. To improve the performance of multi-hop routing in WSN, we propose a model that combines Multi-Objective Particle Swarm Optimization (MOPSO) and a Decision Tree for dynamic CH selection. The proposed model consists of two phases, namely, the offline phase and the online phase. In the offline phase, various network scenarios with node densities, initial energy levels, and BS positions are simulated, required features are collected, and MOPSO is applied to the collected features to generate a Pareto front of optimal CH nodes to optimize energy efficiency, coverage, and load balancing. Each node is labeled as selected CH or not by the MOPSO, and the labelled dataset is then used to train a Decision Tree classifier, which generates a lightweight and interpretable model for CH prediction. In the online phase, the trained model is used in the deployed network to quickly and adaptively select CHs using features of each node and classifying them as a CH or non-CH. The predicted nodes broadcast the information and manage the intra-cluster communication, data aggregation, and routing to the base station. CH selection is re-initiated based on residual energy drop below a threshold, load saturation, and coverage degradation. The simulation results demonstrate that the proposed model outperforms protocols such as LEACH, HEED, and standard PSO regarding energy efficiency and network lifetime, making it highly suitable for applications in green computing, environmental monitoring, precision agriculture, healthcare, and industrial IoT.<\/jats:p>","DOI":"10.3390\/fi17120577","type":"journal-article","created":{"date-parts":[[2025,12,15]],"date-time":"2025-12-15T15:52:59Z","timestamp":1765813979000},"page":"577","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Selection of Optimal Cluster Head Using MOPSO and Decision Tree for Cluster-Oriented Wireless Sensor Networks"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9283-0727","authenticated-orcid":false,"given":"Rahul","family":"Mishra","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication, University of Allahabad, Prayagraj 211002, India"}]},{"given":"Sudhanshu Kumar","family":"Jha","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication, University of Allahabad, Prayagraj 211002, India"}]},{"given":"Shiv","family":"Prakash","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication, University of Allahabad, Prayagraj 211002, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4571-1888","authenticated-orcid":false,"given":"Rajkumar Singh","family":"Rathore","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Cardiff School of Technologies, Cardiff Metropolitan University, Cardiff CF5 2YB, UK"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Yadav, G., Srivastava, G., Shrivastava, A., and Sharma, S.
