This convergence has been fueled by advances in internet technologies which facilitate highly interactive digital encounters across a wide range of applications. This survey provides an in-depth review of the present status of the metaverse, encompassing an analysis of its diverse technologies. We provide an in-depth study of the interdependence of connected technologies in the development of immersive digital realities. Our review encompasses many aspects, including graphical representation, user interaction and security and privacy protocols. We present an in-depth study of the metaverse\u2019s diverse applications in entertainment, education, e-commerce and social interactions. These applications demonstrate the metaverse\u2019s potential to fundamentally transform how we educate, socially interact with each other, or conduct business. The emergence and acceptance of the metaverse also give rise to significant challenges which include the digital divide, ethical considerations, legal frameworks, privacy and security, as well as the potential implications for mental and physical health. This survey will provide a comprehensive guide for researchers, policymakers and technologists as they navigate the transformative digital frontier of the evolving and expanding metaverse. <\/jats:p>","DOI":"10.1142\/s0218126625300077","type":"journal-article","created":{"date-parts":[[2025,4,5]],"date-time":"2025-04-05T04:28:40Z","timestamp":1743827320000},"source":"Crossref","is-referenced-by-count":6,"title":["Metaverse for Connected World: Key Enablers, Challenges and Opportunities"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-0399-9731","authenticated-orcid":false,"family":"Deepanshi","sequence":"first","affiliation":[{"name":"School of Computer Science Engineering and Technology, Bennett University, Greater Noida 201310, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-5232-4320","authenticated-orcid":false,"given":"Yash","family":"Motiani","sequence":"additional","affiliation":[{"name":"School of Computer Science Engineering and Technology, Bennett University, Greater Noida 201310, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9882-3476","authenticated-orcid":false,"given":"Gaurav","family":"Singh","sequence":"additional","affiliation":[{"name":"School of Computer Science Engineering and Technology, Bennett University, Greater Noida 201310, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7495-5032","authenticated-orcid":false,"given":"Ishan","family":"Budhiraja","sequence":"additional","affiliation":[{"name":"School of Computer Science Engineering and Technology, Bennett University, Greater Noida 201310, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9048-6758","authenticated-orcid":false,"given":"Haneef","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, College of Engineering and Computer Science, Jazan University, Jazan, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1206-2298","authenticated-orcid":false,"given":"Pronaya","family":"Bhattacharya","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Amity School of Engineering and Technology, Research and Innovation Cell, Amity University, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0419-1468","authenticated-orcid":false,"given":"Kai","family":"Fang","sequence":"additional","affiliation":[{"name":"College of Mathematics and Computer Science, Zhejiang A&F University, Hangzhou 311300, P.
