Distributed computing enables Internet of vehicle (IoV) services by collaboratively utilizing the resources from network edge and vehicles. However, interruption issue caused frequent handoffs, a severe shortage are two problems in providing IoV services. High altitude platform station (HAPS) can be promising addition to existing distributed frameworks because its wide coverage strong computati...

Low-latency requirements of vehicular networks can be met by installing mobile edge hosts that implement computing in the roadside units (RSUs). Adversaries can, however, compromise these RSUs and use them to launch cyber attacks. In this paper, we consider an adversary selectively drops packets or corrupts between RSU passing vehicles. Such strategies would lead a higher number re-transmission...

A third of the Dutch highways is monitored and controlled by roadside units. These RSUs are safety-critical systems, as they safeguard roadworks accidents. Therefore, it essential to have guarantees on correctness unit controller. Using supervisory control theory, a correct-by-construction supervisor obtained from model system its requirements. From model, controller implementation can be autom...

Vehicular Networks are receiving a lot of attention due to the wide variety of services they can provide. Their applications range from safety and crash avoidance to Internet access and multimedia. A lot of work and research around the globe is being conducted to define the standards for vehicular Communications. These include frequency allocation, standards for physical and link layers, routin...

In this letter, we study the improvement that road-side stations can bring to the multihop connectivity of intervehicle communication in a traffic stream. With a recursive model of connectivity, we study impacts of different densities of road-side stations and different positions of road-side stations for uniform or non-uniform traffic streams.

We propose a hybrid ITS safety architecture that combines vehicle-to-vehicle communication and vehicle-to-roadside sensor communication. Opposed to dedicated roadside units, which require major investments for purchase, installation and maintenance, roadside wireless sensor and networking technology represents a cost-effective solution and can leverage the deployment of the system as a whole. A...

Road safety is a major global concern, as millions of lives are lost every year because road accidents. Towards an effort to increase safety, several Internet-of-Vehicle systems have been developed over the last years in order better monitor vehicle and driver behavior issue warnings that effectively prevent life-threatening These face number challenges including connectivity issues high instal...

This study reviews the impact of roadside friction on urban arterial roads in published literature and aims to identify various side frictional parameters that roads. The are non-motorized vehicles, pedestrian crossing or moving along road, street vendors, on-street parking, animal movement, land-use activity. all these traffic performance leads a reduction capacity, speed (instantaneous speed,...

The prediction of received power in the adjacent zone of a Dedicated Short Range Communications (DSRC) system operating inside an arched transportation tunnel is discussed. Wideband directional channel sounding was conducted inside the tunnel, and the gain, angleof-arrival and delay of each propagation path were estimated from the measured data. By simulating application antennas according to t...

background: the aim of this study was to assess the effects of road deicing salt on the quality of the ground water resources in hamadan province during winter season. methods: water samples were taken monthly from thirty wells located around the hamadan-asadabad highway. the quality of well water was examined by measuring amount of sodium, chloride, total hardness, total dissolved solid, elect...
