The Performance of Realistic Simulation over Vehicular Networks
… can help avoid accidents and traffic congestion. Vehicular Ad-hoc Network (VANET) is a network that involves moving vehicles within certain range of distance to communicate with each other, thus forming a network. A VANET turns every participating vehicle into a wireless router or node that allows …
