Managing heterogenous traffic in VANETs becomes a critical challenge, especially when dealing with critical scenarios. In this paper, we present a novel dynamic fragmentation\u2010based MAC protocol, DFROG\u2010MAC for Internet of Things (IoT) applications in VANET environment. This protocol is focused on facilitating prioritised heterogenous traffic in sensor networks and hence, can offer a distinguished quality of service for various application areas such as vehicular, industrial or body sensor networks. DFROG\u2010MAC deploys fragmentation scheme for low priority data, so the high priority data may interrupt and access channel without needing to wait for the complete transmission of lower priority data. The fragment size for the lower priority data is dynamically adjusted at the runtime based on the frequency of urgent traffic arrival. This dynamic approach helps to ensure that the channel does not remain idle, and lower priority traffic could be served quickly, in the absence of urgent traffic. Two types of traffic priorities, normal and urgent have been used for performance evaluation of FROG\u2010MAC and DFROG\u2010MAC, over Contiki platform, with the scope of this study focused on vehicle\u2010to\u2010infrastructure (V2I) single\u2010hop communication. The delay and throughput both have been found to improve for DFROG\u2010MAC due to the possibility of dynamic fragment size selection.<\/jats:p>","DOI":"10.1049\/wss2.70017","type":"journal-article","created":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T17:20:57Z","timestamp":1760116857000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["DFROG\u2010MAC: A Dynamic Fragmentation\u2010Based MAC for Prioritised Emergency Data Management in Vehicular Networks"],"prefix":"10.1049","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2237-5124","authenticated-orcid":false,"given":"Anwar Ahmed","family":"Khan","sequence":"first","affiliation":[{"name":"Department of Computer Science Millennium Institute of Technology and Entrepreneurship  Karachi Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shama","family":"Siddiqui","sequence":"additional","affiliation":[{"name":"Department of Computer Science DHA Suffa University  Karachi Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad Sami","family":"Al\u2010Shamayleh","sequence":"additional","affiliation":[{"name":"Department of Data Science and Artificial Intelligence Faculty of Information Technology Al\u2010Ahliyya Amman University  Amman Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adnan","family":"Akhunzada","sequence":"additional","affiliation":[{"name":"College of Computing and IT University of Doha for Science and Technology  Doha Qatar"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9669-6417","authenticated-orcid":false,"given":"Indrakshi","family":"Dey","sequence":"additional","affiliation":[{"name":"Walton Institute, South East Technological University  Waterford Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2025,10,10]]},"reference":[{"key":"e_1_2_12_2_1","volume-title":"2020 IEEE 12th International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment, and Management, HNICEM 2020","author":"Gonzales R.
