Vehicular communication systems have significant benefits. Their adoption and use in motor vehicles can help prevent road traffic accidents, increase route efficiency and fuel economy, and positively impact the user experience. As autonomous vehicles and inter-vehicular communication systems are becoming increasingly commonplace, the need for robust and secure wireless communication between vehicles...
Named Data Networking is a new data centric kind of communication network. This paper shows the study about NDN network and applies this architecture over Vehicular ad-hoc networks so that performance of network improves and communication becomes faster. At the end of simulation results are discussed in the form of packet delivery ratio, throughput, good put, routing overhead and various network parameters...
The VANET (Vehicular Ad hoc Network) is a collection of mobile nodes forming a temporary network on variable topology, operating without base station and without centralized administration. The characteristics of VANET network that distinguishes it from other ad hoc networks, such as high mobility and communication with the infrastructure to support security or comfort applications, have prompted...
Vehicle Ad hoc Network (VANET) is an emerging technology and a new application of mobile Ad Hoc technology in the field of traffic. As the simulation experiments cost less manpower and material resources and they are easy to reproduce the same scenario, VANET simulation technology has become a focus of scholars. But node mobility is strictly limited in the realistic traffic environment and fast moving...
Routing in vehicular ad-hoc network is current area of research due to fast mobility of vehicles. A new route in very less time has to be developed to communicate with the base station. If any node behaving like malicious and creates attack on network, than whole communication will be squeeze. This paper presents a routing strategy to prevent from attack and identify the malicious node. The strategy...
Named Data Networking (NDN) is a data-centric architecture designed for the future Internet. Existing works show that NDN brings significant performance improvement for typical content-centric applications, and can also fit the mobile environment well. However, directly applying NDN to Vehicular Ad hoc NETworks (VANETs) is confronted with great challenges due to the high mobility of vehicles. Most...
In this paper, based on an in-depth analysis of Geographical Routing Protocol (GRP), especially its next hop selection, we present an improvement for the strategy of next hop selection with a joint consideration of distance factor and hierarchical quadrant. Based on the next hop selection strategy, an Improved Geographic Routing Protocol (IGRP) has also been proposed in this paper, which has a higher...
Vehicular ad hoc networks (VANET) mean wireless networks where communication terminals in VANETs do not necessarily require infrastructures to communicate with each other. To provide Intelligent Transportation System (ITS) services in VANETs, there are lots of issues about network performances for several application types. In particular, if applications need stable link-status, there are lots of...
Numerous efforts are currently under progress to enhance the safety and efficiency of vehicular traffic through intelligent transportation systems. In addition, the growing demand for access to data and information from human users on the go has created the need for advanced vehicle-to-vehicle and vehicle to roadside communication systems capable of high data rates and amenable to high degrees of...
In VANET, nodes move at high speed and change connecting network frequently. As a consequence, IP duplication may occur and packets would not be sent to the correct destination. This paper aims at reducing the size of location information in duplicate address detection (DAD) scheme. We propose a grid-based duplicate address detection (GDAD) scheme and separate network into several grids, where the...
Vehicular Ad Hoc Network (VANET) is a challenging area of research in the field of vehicular technology. It is an emerging topic for its high mobility and high link disruption. But if link disruption is due to the malicious drivers in the network then it reduces the performance of the network. Hole Generation attack is a kind of attack in which the malicious drivers breaks the communication links...
Vehicular Ad Hoc Network (VANET) is an emerging area of research to provide Intelligent Transportation System (ITS) services to the end users. It is a challenging topic for its high mobility and frequent link disruption. Recently researchers are working on many specific issues related to VANET like routing, broadcasting, Quality of Service (QoS), security, architectures, applications, protocols, etc...
The high mobility and variability of road traffic has hampered the design of efficient communication protocols and the deployment of new services in vehicular networks. Nevertheless, the newly-introduced notion of virtual mobile nodes (VMNs) has the potential to turn wireless ad hoc networks into more predictable environments, facing the significant challenges raised by the mobility of the (real)...
The following topics are dealt with: vehicular networking; beaconing and broadcast; data collection and management; simulation and modelling; transport protocols; mobility management in VANETs; telecommunication security; smart antennas and radio; reliability and routing; cellular networks; physical layer; and MAC.
Operations of vehicular ad hoc networks rely on the collaboration of participating nodes to route data for each other. This standard approach using a fixed set of nodes for each communication link cannot cope with high mobility due to a high frequency of link breaks. A recent approach based on virtual routers has been proposed to address this problem. In this new environment, virtual routers are used...
In vehicular ad hoc networks in a city environment, communication connections need to adapt to fast moving nodes (e.g., vehicles on streets) and large obstacles (e.g., office buildings). Fast moving nodes results in frequent topology changes. Large buildings surrounded by relative narrow streets allow only a short window of communication among nodes. Early solutions address this fundamental requirement...
