Disseminating　Emergency　Messages　(EMs)　to　a　maximum　number　of　vehicles　with　low　latency　in　Vehicular　Ad　Hoc　Networks　(VANETs)　can　help　reduce　road　accidents.　Nevertheless,　timely　delivery　of　EMs　to　a　maximum　number　of　vehicles　while　suppressing　redundant　transmissions　to　avoid　broadcast　storms　is　challenging.　Traditional　cluster-based　EM　dissemination　schemes　treat　all　EMs　equally　and　disseminate　them　across　the　entire　road,　increasing　rebroadcast　ratio　and　message　collisions.　Since　not　all　EMs　need　to　cover　the　entire　road,　it　is　essential　to　broadcast　EMs　based　on　their　Zone　of　Interest　(ZoI).　Therefore,　we　propose　a　cluster-based　scheme　for　EM　Dissemination　in　ZoI　(EMD-ZoI).　The　scheme　uses　information　contained　in　EMs　to　determine　ZoI.　We　also　introduce　a　relay　vehicle　based　on　link　lifetime　to　reduce　retransmissions　and　latency.　Simulation　results　show　that　EMD-ZoI　provides　a　good　performance　gain　in　terms　of　coverage　information,　latency　and　rebroadcast　ratio.　©　2021　IEEE.
