Their dynamic topology, caused by node movement, activation, and deactivation, often relies on controlled flooding for routing, leading to significant resource consumption and network congestion. To address this challenge, we propose the Adaptive Clustering-based Routing Protocol (ACRP). This ACRP protocol uses the common member-based adaptive dynamic clustering approach to produce optimal clusters, and the OppNet is converted into a TCP\/IP network. This protocol adaptively creates dynamic clusters in order to facilitate the routing by converting the network from a disjointed to a connected network. This strategy creates a persistent connection between nodes, resulting in more effective routing and enhanced network performance. It should be noted that ACRP is scalable and applicable to a variety of applications and scenarios, including smart cities, disaster management, military networks, and distant places with inadequate infrastructure. Simulation findings demonstrate that the ACRP protocol outperforms alternative clustering approaches such as kRop, QoS-OLSR, LBC, and CBVRP. The analysis of the ACRP approach reveals that it can boost packet delivery by 28% and improve average end-to-end, throughput, hop count, and reachability metrics by 42%, 45%, 44%, and 80%, respectively.<\/jats:p>","DOI":"10.3390\/info15050283","type":"journal-article","created":{"date-parts":[[2024,5,16]],"date-time":"2024-05-16T03:24:48Z","timestamp":1715829888000},"page":"283","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Optimizing Energy Efficiency in Opportunistic Networks: A Heuristic Approach to Adaptive Cluster-Based Routing Protocol"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6005-2182","authenticated-orcid":false,"given":"Meisam","family":"Sharifi Sani","sequence":"first","affiliation":[{"name":"School of Electrical, Computer and Telecommunications Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9749-7775","authenticated-orcid":false,"given":"Saeid","family":"Iranmanesh","sequence":"additional","affiliation":[{"name":"School of Electrical, Computer and Telecommunications Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}]},{"given":"Hamidreza","family":"Salarian","sequence":"additional","affiliation":[{"name":"Sydney International School of Technology and Commerce, Sydney, NSW 2000, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7561-9903","authenticated-orcid":false,"given":"Faisel","family":"Tubbal","sequence":"additional","affiliation":[{"name":"School of Electrical, Computer and Telecommunications Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2347-4837","authenticated-orcid":false,"given":"Raad","family":"Raad","sequence":"additional","affiliation":[{"name":"School of Electrical, Computer and Telecommunications Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,16]]},"reference":[{"key":"ref_1","first-page":"154","article-title":"Mobility Routing Model for Vehicular Ad-hoc Networks (VANETs), Smart City Scenarios","volume":"9","author":"Abdelgadir","year":"2017","journal-title":"Veh.
