Cooperative vehicular networks require the exchange of positioning and basic status information between neighboring nodes to support vehicular applications. The exchange of information is based on the periodic transmission/reception of 1-hop broadcast messages on the so called control channel. The dynamic adaptation of the transmission parameters when broadcasting such messages will be key for ...

Recently, Vehicular Ad Hoc Networks (VANET) have attracted the attention of research communities, leading car manufacturers, and governments due to their potential applications and specific characteristics. Their research outcome was started with awareness between vehicles for collision avoidance and Internet access and then expanded to vehicular multimedia communications. Moreover, vehicles’ h...

Vehicular air pollution affects both urban and town air quality all around the world. Air quality in many developing countries is deteriorating according to (WHO/UNEP 1992) report because these countries lack the resources to invest in emission control. Global air pollution problems have captured public attention, because of stratospheric ozone depletion and global warming. In response to globa...

In future wireless networks, a significant number of users will be vehicular. One promising solution to improve the capacity for these vehicular users is to employ moving relays or car base stations. The system forms cell inside the vehicle and then uses rooftop antenna for backhauling to overcome the vehicular penetration loss. In this paper, we develop a model for aggregate interference distr...

Vehicles traffic congestion on the road is reflected as delays while traveling. This congestion has a number of negative effects such as energy consumption, wastage of time and increased tailpipes emission of idling vehicles probably bad for our health. Vehicular congestion has become the serious problem and it is getting worse day by day as the growth of the vehicles significantly increased. I...

Advanced heterogeneous vehicular network (AHVN) is a promising architecture for providing vehicular services in the next generation of vehicular networks. AHVN is an integrated architecture between vehicular ad hoc networks and existing cellular wireless networks. In this work, we propose a Multihop vehicular connectivity model in V2V system, which depends on the physical characteristics of the...

In vehicular networks, vehicles exchange messages with each other as well as infrastructure to prevent accidents or enhance driver’s and passenger’s experience. In this paper, we propose a grid-based multichannel access scheme to enhance the performance of a vehicular network. To determine the feasibility of our scheme, we obtained preliminary results using the OPNET simulation tool. Keywords— ...

contemporary literary traumatheory indicates that experiencing trauma creates a fear that destroys identity. in fact, experiencing trauma creates a new identity for the victim. the representation of the trauma and the formation of the new identity for the victim are the building blocks of trauma novels. due to the nature of trauma, it seems impossible to fully describe traumatic experiences by ...

Vehicular Ad Hoc Networks (VANETs) is a type of ad hoc network that allows vehicles to communicate with each other in the absence of fixed infrastructure. Inter-vehicle geographic routing has been proven to perform well in high speed vehicular environments. In connected and reliable vehicular scenarios, greedy based geographical routing protocols could forward data packets efficiently and quick...
