Design of efficient and secured routing protocols for vehicular ad hoc networks vanets

Abstract

newline Vehicular ad hoc networks (VANETs) are a prominent sub-class of Mobile ad hoc newlinenetworks (MANETs) having numerous emerging applications. VANETs support establishing newlineVehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communication. The use of newlineVANETs is increasing at a rapid rate due to their applicability to solve various traffic related newlineproblems and provide a better user experience. Vehicular communication has improved our newlinedaily life a lot through road safety, comfort driving, traffic efficiency, etc. However, VANETs newlinebring several new challenges including routing and security challenges in data communication newlinedue to their special characteristics such as high mobility, dynamic topology, etc. Therefore, newlineacademia, civic bodies, and automobile industry are heavily interested in ongoing research newlineprojects on VANETs. newlineVANETs do not have a controlling authority to manage the network infrastructure. newlineTherefore, data dissemination is one of the remarkable challenges in VANETs. Over the years, newlineseveral efficient routing protocols have been designed to route messages between nodes. newlineHowever, reliability, mobility management, security, and network scalability are few open newlinechallenges in VANETs. In this research, efficient routing protocols have been designed for newlineVANETs. Clustering and Multipath techniques are used to make proposed routing more newlineefficient. In addition to that, the issue of security in VANETs has also been addressed by newlineproposing a security technique. newlineFirst, an effective cluster-based routing algorithm for VANETs has been proposed. newlineUnlike other clustering approaches, RSUs have been considered as fixed nodes in VANETs newlineand treated as cluster heads in this approach. Due to static clusters, the overhead to create and newlinemaintain clusters has been reduced. Multiple clusters in a large network headed by RSUs make newlinerouting more efficient and reliable. Three levels of routing are mentioned in this approach. At newlinefirst level routing, the source vehicle itself is capable to send data to the destination node. newlineSe
