Due to its distributed network and frequently changing topology, it is extremely prone to security attacks. The researchers have proposed different strategies for detecting various forms of network attacks. However, VANET is still exposed to several attacks, specifically Sybil attack. Sybil Attack is one of the most challenging attacks in VANETS, which forge false identities in the network to undermine communication between network nodes. This attack highly impacts transportation safety services and may create traffic congestion. In this regard, a novel collaborative framework based on majority voting is proposed to detect the Sybil attack in the network. The framework works by ensembling individual classifiers, i.e., K-Nearest Neighbor, Na\u00efve Bayes, Decision Tree, SVM, and Logistic Regression in a parallel manner. The Majority Voting (Hard and Soft) mechanism is adopted for a final prediction. A comparison is made between Majority Voting Hard and soft to choose the best approach. With the proposed approach, 95% accuracy is achieved. The proposed framework is also evaluated using the Receiver operating characteristics curve (ROC-curve).<\/jats:p>","DOI":"10.3390\/s22186934","type":"journal-article","created":{"date-parts":[[2022,9,13]],"date-time":"2022-09-13T22:37:28Z","timestamp":1663108648000},"page":"6934","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":60,"title":["Collaborative Learning Based Sybil Attack Detection in Vehicular AD-HOC Networks (VANETS)"],"prefix":"10.3390","volume":"22","author":[{"given":"Sofia","family":"Azam","sequence":"first","affiliation":[{"name":"Department of Computer Science and IT, University of Azad Jammu and Kashmir, Muzaffarabad 13100, CO, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9619-8565","authenticated-orcid":false,"given":"Maryum","family":"Bibi","sequence":"additional","affiliation":[{"name":"Department of Computer Science and IT, University of Azad Jammu and Kashmir, Muzaffarabad 13100, CO, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7154-0926","authenticated-orcid":false,"given":"Rabia","family":"Riaz","sequence":"additional","affiliation":[{"name":"Department of Computer Science and IT, University of Azad Jammu and Kashmir, Muzaffarabad 13100, CO, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4694-3250","authenticated-orcid":false,"given":"Sanam Shahla","family":"Rizvi","sequence":"additional","affiliation":[{"name":"Raptor Interactive (Pty) Ltd., Eco Boulevard, Witch Hazel Ave, Centurion 0157, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6295-7014","authenticated-orcid":false,"given":"Se Jin","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of AI Software, Kangwon National University, Samcheok 25913, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mustafa, A.S., Hamdi, M.M., Mahdi, H.F., and Abood, M.S.
