A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Beaconing approaches is an important research challenge in high mobility vehicular networks with enabling safety applications. In this article, we perform a survey and a comparative study of state-of-the-art adaptive beaconing ...

A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Multi-hop routing and beaconing approaches are two important research challenges in high mobility vehicular networks. Routing protocols are divided into two categories of topology-based and position-based routing protocols. In ...

Low density of network nodes in Vehicular Ad Hoc Networks (VANETs) outside the rush hours and in peripheral areas limits usability of traditional ad hoc networking, which requires end-to-end connectivity between communicating parties. In this article, we survey how usability of vehicular networks could be escalated with delay-tolerant networking, in which vehicles store and carry network data w...

Vehicular Ad hoc Network can ease our life by making driving safe in near future. To make it successful efficient routing protocols need to be used for communication among vehicles. This communication can be direct within vehicles and can be through road side units (RSUs). In this paper we are exploiting the AODV, DSR and DSDV routing protocols by comparing their performances with respect to th...

Security and protection of private user information are a prerequisite for the deployment of the vehicular network technologies. Nevertheless, the establishment of a secure communication architecture within vehicular ad hoc networks address special challenges, due to the characteristic and specificities of such environment (high dynamic and mobility of nodes, high rate of topology changes, high...

Vehicular Ad-hoc Networks (VANETs) are MANETs (Mobile Ad-hoc Networks) in which the network nodes are primarily located in vehicles. VANETs are a compelling application of ad-hoc networks, because of the potential to access specific context information (e.g. traffic conditions, service updates, route planning) and deliver multimedia services (VoIP, in-car entertainment, instant messaging, etc.)...

Mobile ad hoc networks are becoming very popular in wireless communications due to the latest advances in technology. This has allowed millions of people to communicate with each other over wireless networks using mobile devices. Moreover, the latest models of many vehicles are equipped with communication devices which allow them to form a new type of ad hoc wireless networks, called Vehicular ...

Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...

Vehicular networks are characterized by unique properties and challenging problems. The high mobility and density of nodes impede the direct utilization of traditional techniques and protocols in this context. In particular, automatic IP address configuration in vehicular ad-hoc networks is a challenging and as yet unexplored issue. The importance of this problem cannot be overemphasized since ...

A Vehicular Ad-Hoc Network is a kind of ad-hoc network, and is a self-configuring network of vehicular routers connected by wireless links. Vanet presents new and promising field of research, development and standardization. Vehicular Ad-Hoc Network is a wireless network without infrastructure. Reliable broadcasting in vehicular ad-hoc networks is one of the keys to success for services and app...
