For an efficient vehicular Adhoc network, broadcasting i.e. sharing a safety related message across all vehicles and infrastructure throughout the network is pivotal. Hence an efficient TDMA based MAC protocol for VANETs would serve the purpose of broadcast scheduling. At the same time, high mobility, influential traffic density, and an altering network topology makes it strenuous to form an efficient broadcast schedule. In this paper an evolutionary approach has been chosen to solve the broadcast scheduling problem in VANETs. The paper focusses on identifying an optimal solution with minimal TDMA frames and increased transmissions. These two parameters are the converging factor for the evolutionary algorithms employed. The proposed approach uses an Adaptive Discrete Firefly Algorithm (ADFA) for solving the Broadcast Scheduling Problem (BSP). The results are compared with traditional evolutionary approaches such as Genetic Algorithm and Cuckoo search algorithm. A mathematical analysis to find the probability of achieving a time slot is done using Markov Chain analysis.<\/jats:p>","DOI":"10.3233\/jifs-189134","type":"journal-article","created":{"date-parts":[[2020,8,11]],"date-time":"2020-08-11T17:53:16Z","timestamp":1597168396000},"page":"8125-8137","source":"Crossref","is-referenced-by-count":3,"title":["Optimal broadcast scheduling method for VANETs: An adaptive discrete firefly approach"],"prefix":"10.1177","volume":"39","author":[{"given":"Jackson J","family":"Christy","sequence":"first","affiliation":[{"name":"School of Computing Science and Engineering, Vellore Institute of Technology, Chennai Campus, Chennai, Tamilnadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D","family":"Rekha","sequence":"additional","affiliation":[{"name":"School of Computing Science and Engineering, Vellore Institute of Technology, Chennai Campus, Chennai, Tamilnadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V","family":"Vijayakumar","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, University of New South Wales, Sydney, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Glaucio H.S.","family":"Carvalho","sequence":"additional","affiliation":[{"name":"School of Applied Computing, Sheridan College, Oakville, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"key":"10.3233\/JIFS-189134_ref2","doi-asserted-by":"crossref","first-page":"9497","DOI":"10.1109\/ACCESS.2017.2692240","article-title":"Routing in Vehicular Ad-hoc Networks: A Survey on Single- and Cross-Layer Design Techniques, and Perspectives","volume":"5","author":"Awang","year":"2017","journal-title":"IEEE Access"},{"issue":"9","key":"10.3233\/JIFS-189134_ref3","doi-asserted-by":"crossref","first-page":"1724","DOI":"10.1109\/TMC.2012.142","article-title":"VeMAC: A TDMA-Based MAC Protocol for Reliable Broadcast in VANETs","volume":"12","author":"Omar","year":"2013","journal-title":"IEEE Transactions on Mobile Computing"},{"key":"10.3233\/JIFS-189134_ref4","unstructured":"802.11p-2010 - IEEE Standard for Information technology\u2013Local and metropolitan area networks\u2013Specific requirements\u2013Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications Amendment 6:Wireless Access in Vehicular Environments - IEEE Standard.
