In vehicular ad hoc network (VANETs), vehicles travel at high speed from one place to another that create certain issues like congestion, delay and high power consumption. Reducing the delay and power consumption is the primary task to achieve an effective performance among the vehicles. For that purpose in this article cluster head ($\mathbf{C H}$) selection and the data dissemination with multicast protocol (CHDMV) is concentrated. The subsections of this model are the vehicles clustering process, cluster maintenance and multicast protocol, with the presence of this processes the efficiency of the network is improved even if the vehicle travels at high speed with rapidly changing topology. The parameters which are measured to analyze the outcomes are packet delivery ratio, network throughput, average delay, energy efficiency and routing overhead. From the calculator result it is shown that the CHDMV achieves maximum performance in terms of the efficiency and delivery ratio.
