Vehicular ad-hoc network (VANET) is high dynamic wheeled networks in which moving vehicles that can move in any direction at varying speed are behave as network nodes and router for data exchange. The frequently changes in topology and mobility pattern in VANET pose many unique networking research challenges which make crucial the designing of an new suit of efficient routing protocol for VANET...

Vehicular ad hoc networks (VANETs) are receiving increasing attention from academics due to the various applications and potential tremendous benefits they offer for future VANET users. Safety information exchange enables lifecritical applications, such as the alerting functionality during medical emergencies, and thus, plays a key role in VANET applications. In a VANET, vehicles rely on the in...

In the present study we have proposed a secured geocaste routing in VANET with two stage efficient communication protocol. The communication protocol operates on two stages. In the first stage vehicles transmit messages within its transmission range of its radar and to the VANET Server. In the second stage VANET Server receives messages from vehicles and sends those messages to all other vehicl...

Vehicular ad hoc network is one of the most promising applications of MANET that an inter communication system. In VANET nodes which are vehicles can move safety with high speed and generally must communicate quickly reliably. When an accident occurs in a road or highway, alarm messages must be disseminated, instead of ad hoc routed, to inform all other vehicles. Vehicular ad hoc network archit...

Vehicle ad hoc network (VANET) is an open communication environment. Any user can broadcast messages, which means that it be easily attacked by malicious users. Therefore, the authentication of vehicles needed. In this paper, we propose a Chebyshev polynomial-based conditional privacy-preserving and group-key agreement scheme for VANET. Specifically, solve three problems in VANET: (1) improve e...

today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...

In metro cities, the effective and efficient management of traffic is one most demanding time taking tasks. Vehicular ad hoc networks (VANET) provide unfailing, low-cost solutions for transportation systems with intelligence. VANET, a subclass mobile (MANET), allows exchange information among vehicles and/or roadside devices. VANET can be implemented in numerous application areas such as manage...

A vehicular ad hoc network (VANET) consists of vehicles, roadside units, and other infrastructures that communicate with each the goal improving road safety, reducing accidents, alleviating traffic congestion. For safe secure operation critical applications in VANET, it is essential to ensure only authenticated vehicles can participate network. Another important requirement for VANET communicat...

Security in vehicular ad hoc network (VANET) is one of the major challenging topics and secure key interchange between two legitimate vehicles an important issue. The multi-environment VANET has been exploited to extract secret employed security services VANET. However, it offered more excellence randomness owed fading, noise multi-path, velocity difference. Some factors like Bit-rate, complica...

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...
