| Summary: | Because of the dynamic vehicle density, vehicle speed, and unexpected and harsh communication environment, the Vehicular Ad Hoc Network (VANET) differs from conventional ad hoc networks in terms of functioning. VANET has two primary applications: safety and non-safety. Network optimization is one method of preserving current protocols and other network characteristics rather than inventing and implementing new enhanced protocols, which is prohibitively expensive. As a result, this study proposes an optimization city scenario of VANET for maximizing throughput and packet delivery ratio (PDR) while reducing delay using the Taguchi method. For three target performances evaluated, packet size has the highest rank control factors for two conditions. Packet size plays the major control factor in contributing to lower delay and maximizing throughput. Therefore, packet size is a major control factor and is applicable for optimizing both safety and non-safety applications focusing on the city scenarios of VANET. © 2021 IEEE.
