Vehicular networking is an emerging area of interest in the wireless networking community as well as in the transportation research community. Vehicular ad hoc networks (vanet) are distributed, self-organizing communication networks which progressed from traveling vehicles, and are thus characterized by very high speeds and limited degrees of freedom in node (vehicle) movement patterns. Differe...

Vehicular Ad-hoc Networks (VANETs) are the most prominent enabling network technology for Intelligent Transportation Systems(ITS).VANETs provides many new exciting applications and opportunities albeit transportation safety and facilitation applications are their core drivers. Security of vehicular networks remains the most significant concern in VANETs deployment – because it is mandatory to a...

Vehicular Ad-hoc Networks (VANETs) are known as a special type of Mobile Ad-hoc Networks (MANETs) specialized in vehicular communications. These networks are based on smart vehicles and basestations, which share data by means of wireless communications. To route these information, a routing protocol is required. Since the VANETs have a particular network features as rapidly changeable topology,...

Vehicular Ad Hoc Network (VANET) has been drawing interest among the researchers for the past couple of years. Though ad hoc network or mobile ad hoc network is very common in military environment, the real world practice of ad hoc network is still very low. On the other hand, cloud computing is supposed to be the next big thing because of its scalability, PaaS, IaaS, SaaS and other important c...

With the development of IoT, Vehicular Ad-hoc Network will be shifted to Vehicular Ad-hoc Network managed cloud in near future. As the traditional cloud, VMM is a crucial problem in Cloud Based Vehicular Networks. Due to the distinct feature of high mobility, VMM Cloud Based Vehicular Networks need to be addressed to keep cloud services running on. When a vehicle moves on the road, it moves out...

During the last decade, the research on vehicular networks has led to the proposal of countless network solutions specifically designed for vehicular environments. Such solutions encompass all network paradigms,with original algorithms and architectures proposed for next-generation roadside cellular access networks, pure vehicular ad hoc networks, and opportunistic disruption-tolerant vehicular...

With the unparalleled growth of motor vehicles, traffic accident between pedestrians and vehicles is one of the most serious issues in the word-wild. Plenty of injuries and fatalities are caused by the traffic accidents and crashes. The connected vehicular ad hoc network as an emerging approach which has the potential to reduce and even avoid accidents have been focused on by many researchers. ...

Now a day’s Vehicular Ad Hoc Network (VANET) is an emerging technology. Mobility management is one of the most challenging research issues for VANETs to support variety of intelligent transportation system (ITS) applications. VANETs are getting importance for inter-vehicle communication, because they allow the communication among vehicles without any infrastructure, configuration effort, and wi...

In this work we describe VIVAGr, a graphicaloriented real time visualization tool for vehicular ad-hoc network connectivity graphs. This tool enables the effective synthesis of structural, topological, and dynamic characteristics of VANET graphs, with a variety of parameters that affect the shape and characteristics of a vehicular ad hoc network (wireless range, mobility models, road-network to...

In this paper, system operating margin (SOM) is estimated for vehicular ad-hoc networks in absence and presence of Rayleigh fading. The Ad-hoc IEEE 802.11 model is considered for estimating the signal strength and system operating margin. Rayleigh fading was then simulated and system operating margin are estimated in Rayleigh fading environment for different standard modulation schemes. Keyword...
