In this paper, we present the VD4 model for effective delivery of data packets in vehicular ad hoc networks. The major challenges in such networks are disconnections, high mobility and resource poor environment. For providing data delivery under such constraints we adopt the method of carry and forward in which a vehicle transfers its data to another vehicle if it is moving towards the destination...
There are many parameters that affect the performance of vehicular ad hoc networks (VANETs) applications and protocols. To test the new applications and protocols on a real setup is very difficult and very costly. Most researchers use simulation tools to study and analyze VANETs. The simulators usually use simple radio propagation models that did not take into account all the obstacles in the environment...
