Now–a–days Vehicular Ad Hoc Networks (VANETs) has attracted the attention of both the industry and academia. Roadside units (RSUs) are one of the fundamental components of Vehicular ad hoc network (VANET). VANET comprises of moving vehicles communicating with each other. During the initial stages of VANET, it is not possible to deploy more and more number of RSUs; it is so because of the lack o...

Vehicular Ad-hoc Networks (VANETs) have seen significant advancements in technology. Innovation in connectivity and communication has brought substantial capabilities to various components of VANETs such as vehicles, infrastructures, passengers, drivers and affiliated environmental sensors. Internet of Things (IoT) has brought the notion of Internet of Vehicles (IoV) to VANETs where each compon...

A Vehicular Ad Hoc network (VANET) is an emerging technology among the scholars and vehicular industries in recent years. The wireless collision Avoidance (CA) system sends early message to drivers before they reach accident zone on the road. This paper proposed an analytical model for warning messages through collision avoidance (CA) system. Use the Dichotomized head way model, the Braking mod...

Blockchain is an emerging computing platform that provides recording and tracking facilities to substantially increase the security issues in healthcare systems. The evolution of wireless body area networks requires continuous monitoring health parameters traveling patients while on road. parameter data each patient are sent Road Side Units (RSUs) for generating blocks by required hash function...

We discuss how to efficiently forward data in vehicular networks. Existing solutions do not make full use of trajectory planning of nearby vehicles, or social attributes. The development of onboard navigation system provides drivers some traveling route information. The main novelty of our approach is to envision sharing partial traveling information to the encountered vehicles for better servi...

Wireless technologies are making the development of new applications and services in vehicular environments possible since they enable mobile communication between vehicles (V2V), as well as communication between vehicles and infrastructure nodes (V2I). Usually, V2V communications are dedicated to the transmission of small messages mainly focused on improving traffic safety. Instead, V2I commun...

Many safety and non-safety related applications have been envisioned in VANETs. However, efficient data dissemination considering the mobility of vehicle is must for the success of these applications. Although the Road Side Unit (RSU) is a stationary unit, both RSU and vehicle have limited transmission range that restricts to shorter connection time. This endures a higher request drop rate spec...

Authentication as a security key issue is required for securing the inter-vehicle communication. Mostly, authentication schemes that depend on the network infrastructure Road Side Unit (RSU) had been proven to have low computation and communication overhead. RSUs may become unavailable due to congestion or failure conditions. Replicating authentication service offered by RSUs to trusted vehicle...

Security and privacy are considered as two main challenges in Vehicular Ad Hoc Network (VANET). To cope with these order to improve the safety of VANET, we propose a secure privacy-preserving authentication scheme. In proposed scheme, Quotient Filter (QF) is used address node while message done based on Elliptic Curve Cryptography (ECC). Besides, each vehicle mapped different pseudo-identity pr...

Vehicular ad hoc networks (VANETs) enable vehicles to communicate with each other but require efficient and robust routing protocols for their success. In this proposed system, we exploit the infrastructure of Road Side units (RSUs) to efficiently and reliably route packets in VANETs. This system operates by using vehicles to carry and forward messages from a source vehicle to carry and forward...
