Analysis of AODV over increased density and mobility in Intelligent Transportation System

Currently the area of VANET lacks in having some better designed algorithms to handle dynamic change and frequent disruption due to the high mobility of the vehicles. There are many techniques to disseminate messages across moving vehicles but they are all highly dependent on some conditions involving flow, density and speed. The two commonly used techniques are AODV (Ad Hoc on Demand Distance Vector) and DSRC (Dedicated Short Range Communication. This study is focused on the use of AODV in Intelligent Transportation System. The under considered parameters are density and mobility. Some limitations in the working of AODV routing protocol has been identified and proved. These limitations can be removed to some extent in order to increase the performance of vehicular networks and make the driving safer and easier for a normal user. This will also remove the implementation complications and an efficient system implementation will be possible.
