Multi-hop vehicle-to-vehicle communication is useful for supporting many vehicular applications that provide drivers with safety and convenience. Developing multi-hop communication in vehicular ad hoc networks (VANET) is a challenging problem due to the rapidly changing topology and frequent network disconnections, which cause failure or inefficiency in traditional ad hoc routing protocols. We ...

Today's era is the era of Automobiles. The numbers of vehicles on the road are increasing rapidly. Drivers have a very little time to react while driving vehicle on a very high speed. So they need to be aware about the traffic conditions, accidents, road jams and other such emergencies. So Vehicular Ad Hoc Network can be used as a tool to improve the road safety by circulates the information. V...

VANET (Vehicular Ad Hoc Network) is a special case about MANET (Mobile Ad Hoc Network), has also received extensive attention as a part of ITS(Intelligent Transportation System). Mobility model is the basic research in VANET, our objective is set up a vehicular mobility model reflecting the real-world scene. In this paper, we propose a mobility model at intersection and present mathematical ana...

Vehicular Ad hoc Networking (VANET) is a network that helps a vehicle to send information to neighboring vehicles, and data packets are transmitted from one vehicle to another vehicle. In VANET, Connection Breakage is an important issue in the existing routing protocols like Ad hoc On-demand Distance Vector (AODV), DSR, DSDV. In this paper, an analysis of Throughput and Control Overhead is done...

Vehicular Ad Hoc Network (VANET) or vehicle network is a technology developed for autonomous vehicles in Intelligent Transportation Systems (ITS). The communication system of VANET using wireless that potentially being attacked. Sybil attack one the attacks occur by broadcasting spurious information to nodes and could cause crippled network. strikes camouflaging themselves as node providing fal...

Vehicular Ad-hoc Network (VANET) is a type of wireless network with Dedicated Short-Range Communication (DSRC) that enables communication between vehicles (V2V) and to infrastructure around them (V2I). VANET has several security requirements consider in order maintain the functionality. Availability most important requirement due its responsibility maintaining functionality network, attack on a...

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...

Vehicular Ad-hoc network (VANET) is constructed with vehicles and roadside infrastructure. Vehicle location and speed information is collected continuously to manage the VANET communication. On-Board Unit (OBU) processes the data from the various sensors on the inside of the cars, and there are conditions of the vehicles. An on-board unit (OBU) is responsible for the communication with external...

Vehicular Ad-hoc Network (VANET) is a growing technology that utilizes moving vehicles as mobile nodes for exchanging essential information between users. Unlike the conventional radio frequency based VANET, Visible Light Communication (VLC) used in VANET to improve throughput. However, road safety considered significant issue users of VANET. Therefore, congestion-aware routing required be deve...
