A Road Accident Prevention (RAP) scheme based on Vehicular Backbone Network (VBN) structure is proposed in this paper for Vehicular Ad-hoc Network (VANET). The RAP scheme attempts to prevent vehicles from highway road traffic accidents and thereby reduces death and injury rates. Once the possibility of an emergency situation (i.e. an accident) is predicted in advance, instantly RAP initiates a ...

Cooperative systems based on Infrastructure-to-Vehicle (I2V) wireless communication offer promising opportunities for automotive safety and traffic efficiency improvements. This research proposes a cooperative traffic-light system based on wireless I2V communication between vehicles and fixed Road Side Units (RSUs) deployed at intersections. This application, called the Cooperative Traffic Ligh...

Excitatory pyramidal neurons and inhibitory interneurons constitute the main elements of cortical circuitry and have distinctive morphologic and electrophysiological properties. Here, we differentiate them by analyzing the time course of their action potentials (APs) and characterizing their receptive field properties in auditory cortex. Pyramidal neurons have longer APs and discharge as regula...

Response modulation by prior sensory stimulation is a common property of cortical neurons. The degree to which effects are specific to the adapting stimulus provides insights into properties of the underlying circuitry. Here, we examined the effects of an adapting whisker deflection's angle on the angular tuning of layer IV barrel neurons and their major input source, thalamic barreloid neurons...

Healthcare application is one of the most promising developments to provide on-time demand services end users, vehicles, and other Road Side Units (RSUs) in urban environment. In recent years, several interfaces have been developed connect, communicate, share required from source another. However, environment holds a complex entity both homogenous heterogeneous devices which communication/sensi...

The roadside unit (RSU) plays an important role in VANET environments for privacy preservation. In order to conserve the privacy of a vehicle, the issued certificate must be updated frequently via RSUs. If a certificate expires without being updated, the services for the vehicle will be terminated. Therefore, deploying as more as possible RSUs ensures that the certificate can be updated before ...

Security and privacy are the most important concerns related to vehicular ad hoc network (VANET), as it is an open-access self-organized network. The presence of ‘selfish’ nodes distributed in taken into account challenge a security threat VANET. A selfish node legitimate vehicle which tries achieve benefit from by broadcasting wrong information. An efficient proper model can be useful tackle a...

VANETs are a subclass of mobile ad hoc networks (MANETs) that enable efficient data transmission between vehicles and other vehicles, road side units (RSUs), infrastructure. The purpose VANET is to enhance security, traffic management, traveler services. Due the nature real-time issues such as reliability privacy, messages transmitted via must be secret confidential. As result, this study provi...
