Abstract
Vehicular Ad hoc Networks (VANETs) play an important role in future, for on road V2V communication systems and related applications like self-organizing, acquiring traffic information using sensors and disseminating it to the nearby vehicles, which are based on broadcast/geo-cast transmission schemes. These networks allow vehicles to share traffic, alerting information with each other during travelling. To achieve this goal successfully, a secured mechanism must be designed to guarantee that no false/malicious vehicles can intercept, or modify the information. It is a challenging task to develop a efficient reliable routing algorithm for VANETs due to the high mobility and the frequent changes of the network topology. In this paper, we propose a new vehicular reliability model to find the reliable route in VANETs. The reliable path is calculated using the location, direction and velocity information of vehicles along the road. Furthermore, proposed scheme guarantees the reliability and timely delivery of messages. Mobile agent based scheme exhibits better bandwidth usage and packet delivery ratio.
