Epidemic and transmission priority based data dissemination model in vehichular adhoc networks (VANETs)

摘要: Vehicular Adhoc Networks (VANETs) is one of the prominent and most important technologies that have reached a milestone in today’s modern world. One key functions VANET known to be data dissemination attracted researchers deal problem technical aspects towards its development. As collective perception technique used by VANETs for expanding perceptual range road traffic sharing sensor regarding objects region using Vehicle-to-Vehicle communication. However, hidden terminal packet collision occurs due high vehicle density which makes more difficult deliver messages contains data. In this paper, proposed Epidemic Transmission Control Priority (ETCP) based model presented. The controlling transmission frequency or avoid find infected number vehicles are affected message without network overload. Furthermore, selected automatically with probability broadcasting simulation results ETCP algorithm compared existing Epic Condensation Based Forwarding (CBF) algorithms, where delay as low 214 millisecond lower when other models. Packet delivery ratio 99.12% significantly higher performance evaluation shows can deliberately accidents minimize overhead comparing techniques.
