Broadcasting is a part of the communication spectrum supported by VANETs through which information is disseminated to all the vehicles in the network. The dissemination process requires multiple retransmissions to achieve network coverage in a multi-hop environment. However, unsupervised retransmissions cause broadcasting storm, whereas on the other hand network coverage is cannot be achieved without retransmissions. In order to achieve network coverage without creating broadcast storm, the work in [1] proposed the modified Genetic Algorithm based on the analytic fitness function in static highway scenario. In this paper, we use the same approach of the modified GA in a dynamic highway environment. The paper introduces vehicular movement in the model under study by proposing the vehicle speed between 60 and 100 km/h. The result shows minor differences in the number of of retransmissions as well as propagation time for both static and dynamic highway scenario. This is due to the fact that the distance covered by the vehicles movement during the time period required to achieve network coverage is too small.
