Improving quality of service through road side back-bone network in VANET

The vehicular ad hoc networks (vanets) are expected to support a large spectrum of traffic alert,dynamic route planning,file sharing,safety and infotainment applications to improve traffic management. user satisfaction plus in time delivery of real-time messages is the most significant quality evaluation criterion for vehicular applications. high mobility and rapidly changing topologies always lead to intermittent quality of services,higher delay and packet dropping issues in network. to improve the quality of services for multi-hop and dynamic environment,different types of solutions have been proposed. the article introduces multi-protocol label switching based on roadside backbone network to provide widespread,scalable,high-speed,robust quality of services and improve network efficiency. the simulation results showed that proposed model improves data transmission and routing performance in terms of data delivery,throughput,end-to-end delay and achieve adequate utilization of resources. © 2016 penerbit utm press. all rights reserved.
