Abstract

Exciting features like on-demand video streaming in vehicles, profound traffic analysis and automatic flooding of emergency, safety measures from vehicles attracts researchers to dig out more innovations in the field of intelligent transportation system (ITS). Therefore, VANET’s plays major role in development of ITS. Such applications require highly reliable communication paths and stable cooperative nodes to support high quality data delivery within expected time. Earlier, a lot of research has been carried out in this area using network formed by vehicles alone and efficiently handles path construction process. But, in certain situations like when the cluster head not able to find an immediate neighbor for forwarding critical information through network might causes inconvenience, also chances of great damage for vehicles along the path. To address this issue in our proposed model, both vehicles and mobile nodes is used dynamically to establish a path depending on situation. And analysis shows there is a significant part of improvement in network performance in aspects of throughput and packet delivery ratio.
