An empirical routing Protocol and data dissemination model in Vehicular adhoc networks vanets

Abstract

One of the important innovations for an intelligent newlinetransportation framework is known to be Vehicular Ad hoc Networks newline(VANETs) that achieves intelligent inter-vehicle communications and newlineimprovement in efficiency and safety for road traffic. Data newlinedissemination has a wide range of observation by the researchers in newlineorder to ensure the security and efficiency in both Vehicle-to- newlineInfrastructure and Vehicle-to-Vehicle communication models. In this newlineresearch, development of an efficient routing mechanism and data newlinedissemination model is focused. First, we proposed Reputation-based newlineWeighted Clustering Protocol (RBWCP) scheme and Firefly algorithm newlineis used for tuning the parameters, and spiteful routing behavior is newlinecountered. Secondly, Epidemic and Transmission Control Protocol newline(ETCP) algorithm is proposed for faster data transmission with direct newlineV2V communications from source to destination. The traffic is avoided newlineby reducing the transmission frequency for huge number of vehicles. newlineFinally, we proposed Epidemic and Transmission-Segment based newlineGeographic Routing (ETSGR) protocol for improving the transmission newlineof information dissemination using the segment formation. From the newlineanalysis, the proposed models are analyzed based on various newlineperformance metrics such as packet delivery ratio, average number of newlineclusters, transmission time, cluster packet overhead, compactness, endto- newlineend delay, one hop link disconnection, and data throughput. newlineSimulation results show that the proposed models seem to be newlineoutperforming when compared other existing protocols and newlinedissemination techniques which obtains relatively high performance in newlinetransmission of data from source to destination newline
