information dissemination in vanet thesis

In the vehicular ad hoc networks several types of data are disseminated and transmission protocol changes with change in the type of data. Some information is useful for only those vehicles which are in certain specific range or location. Dissemination of traffic update message to all the vehicles is wastage of channel bandwidth. In our proposed method, vehicles which are already trapped in the traffic jam are transmitting traffic update message that is disseminated to the vehicles which might be trapped to the traffic jam. Simulation results demonstrate that the proposed protocol reduces congestion in the dense traffic region and efficiently utilizes the bandwidth in stressful road scenarios.

They are self-organized, self-configured and self-controlled infrastructure-less networks. This kind of network has the advantage of being able to be set-up and deployed anywhere and anytime because it has no infrastructure set-up and no central administration. Distributing information between these vehicles over long ranges in such networks, however, is a very challenging task, since sharing information always has a risk attached to it especially when the information is confidential. The disclosure of such information to anyone else other than the intended parties could be extremely damaging, particularly in military applications where controlling the dissemination of messages is essential. This thesis therefore provides a review of the issue of security in VANET and MANET; it also surveys existing solutions for dissemination control. It highlights a particular area not.
