Abstract: One of the main objectives of smart transport systems is to improve road safety. Ad hoc vehicle networks use vehicle accident alert systems that broadcast crashes to vehicles. Reliable and timely receipt of messages are two of the main intents for the creation of VANET security alert protocols. Existing techniques make it hard to meet both objectives at the same time. With the proposed suggestion, the vehicle transmits all the accident warning messages by employing the combined cluster and broadcast technique. The multi-hop message dissemination in VANET involving the selection process of relay vehicles in our proposed combined approach helps to improve performance in terms of reduced collision and reliability in terms of improved reachability and thus helps faster dissemination of emergency messages which in turn reduces the further impact of emergency situations.
