*6.1. Simulation Setup*

For the simulation of the proposed CMC scheme, we used Network Simulator 2 (NS2). The simulation parameters are described in Table 4. We run the simulations for 400 s in an urban environment. We deploy 200 vehicles on the real world map created with SUMO. The simulation area is approximately 5249 × 5053 square meters. The speed range is up to 10 m per second in the road network. We use SUMO for realistic mobility generation of vehicular networks. The OpenStreet map is used to provide a real world road scenario, as shown in Figure 9. The map is converted into SUMO to generate vehicle traffic on a real-world map. The vehicle mobility model file is generated with the help of SUMO. The simulation is run with diverse vehicle traffic densities.
