In Vehicular Ad Hoc Networks (VANETs), the node mobility leads to network topology changed frequently. Due to the vehicle movement, the limited wireless resources and channel fading, the routing protocols in Mobile Ad Hoc Networks MANETs are not suitable for VANETs. In this paper we propose a new multipath route protocol based on Ad hoc On-Demand Distance Vector Routing (AODV) for adapting VANE...

Vehicular ad hoc networks (VANETs) have evolved considerably over the last years, but despite the wide number of potential applications, VANETs also raise a broad range of critical security and privacy challenges. To achieve privacy, VANETs enforce the concepts of authentication and authorisation via public key infrastructures, relying on a large set of regional certification authorities with e...

It is well recognized that security is vital for reliable operation of vehicular ad-hoc networks (VANETs). Location privacy is one of the main security challenges in VANETs, which is concerned with preventing an attacker from tracking a specific vehicle. In this paper, we propose a novel location privacy preservation scheme for VANETs using random encryption periods (REP). REP is based on a pri...

Vehicular ad hoc networks (VANETs) have recently caught the researcher’s attention, due to VANETs promising impact regarding with the applications of Intelligent Transportation System (ITS). Currently, dissemination algorithms help to ensure the adequate performance of communication systems required by the applications of ITS. However, high mobility and constant changing topology in VANETs incr...

Vehicular ad hoc networks (VANETs) are envisioned to provide promising applications and services. One critical deployment issue in VANETs is to motivate vehicles and their drivers to cooperate and contribute to packet forwarding in vehicle-to-vehicle or vehicle-to-roadside communication. In this paper, we examine this problem, analyze the drawbacks of two straightforward schemes, and present a ...

In recent years VANets have come up as new information promulgation technology. To enhance vehicle and road safety, traffic efficiency, and ease as well as comfort to both drivers and passengers, VANets become an active area of research. In VANets, vehicle work as a node. Vehicle collect different types of information like road traffic and environmental information and transmit them to intended...

The development in the field of Intelligent Transportation System (ITS) is growing exponentially with the advancement of Vehicular Ad-hoc NETworks (VANETs). Vehicular networks have gained notable attention among the researchers from both industry and academia due to major research going in the era of smart cities. There exist many standards for wireless access in VANETs such as 2G, 2.5G, 3G, 4G...

Vehicular Ad hoc Networks (VANETs) have emerged recently as one of the most attractive topics for researchers and automotive industries due to their tremendous potential to improve traffic safety, efficiency and other added services. However, VANETs are themselves vulnerable against attacks that can directly lead to the corruption of networks and then possibly provoke big losses of time, money,...

The main aim of this paper is to present comprehensive study on the performance and behavior of Ondemand Distance Vector Routing approach (AODV), Table Driven Routing approach (DSDV) and Hybrid Routing approach (ZRP) in VANETs. VANETs are an enhanced form of MANETs where moving nodes are replaced by vehicles. This paper evaluates these protocols under realistic mobility models to analyze their ...
