“…The best to describe Nakagami radio propagation model is the mathematical general modeling of a radio channel with fading. It was found by existing research in [19] that this model has more configurable parameters. This model is also used to classify the statistics of signals transmitted over the multipath fading channel since it can flexibly model various fading conditions [13].The aim is to enable the wireless communication channel to be more closely represented, which could define various parameter values.…”

“…The simulations are conducted for six times according to different number of vehicles for each type of RPM which are 50, 60, 70, 80, 90 and 100 vehicles. For connections that carry traffic at a constant bit rate, CBR was used for the simulation, where there is an implicit dependency on time synchronization between the source of traffic and the destination [19]. Traffic modelling which is CBR used in NS-2 along with the transport protocols, TCP and UDP, in order to design the traffic source behaviour of packets.…”

Vehicular Ad-hoc Network (VANET) is developed for the communication between vehicle-to-vehicle and vehicleto-roadside in purpose for safety, navigation and other roadside services. The radio propagation model (RPM) was used in VANET for the implementation of VANET in order to estimate the path loss in multiple operating environments such as modern road infrastructure. This research is concerned with the study about the performance of different RPM on VANET between Free Space propagation, Two Ray Ground propagation and Nakagami propagation. The purpose of this research work is to observe the packet loss, throughput and average end-to-end delay between vehicles by implementing different type of RPMs, which then has been compared to determine which RPM has a better performance. To obtain the performance analysis of RPM in VANET, several software such as Java OpenStreetMap (JOSM), Simulator of Urban Mobility (SUMO), Mobility Model Generator for VANET (MOVE) and Network Simulator Version 2 (NS2) has been used with Linux Ubuntu version 20.04 as the operating system. The data were collected at Jalan Besar Selayang Baru, 68100 Batu Caves, Selangor. With the target location of 2 km x 2 km size, detail analyzation of data from all three different propagation models were performed. Hence, the best performance of RPM in VANET has been identified.
