Intelligent Transportation Systems (ITS), one aspect of the Smart City paradigm, aim to improve efficiency, convenience, and safety travelers. The integration (vehicular) communication technologies allows between on-board units (OBUs) vehicles, roadside (RSUs), vulnerable road users (VRUs), contribute efficacy ITS applications. However, these additional sources information must be reliable accu...

The development of applications based over vehicular networks, such as road safety, environmental information etc. require a complete testbed platform for research and evaluation. Such a platform will be provided by NITOS[1] testbed, that will include nodes mounted on cars and fixed nodes of the testbed operating as road side units (RSU). Besides the wireless infrastructure, there will be sever...

Today Vehicular Ad-hoc Networks (VANETs) are needful to improve safety on the roads. But using this kind of networks has a few issues. Providing security is one of the most important issues that users of VANETs are associated with. Our purpose of security is the reliability of information. Security is lost when a user or group of users try to send invalid information into the network for their ...

Video streaming over vehicular networks is an attractive feature to many applications, such as emergency video transmission and inter-vehicle video transmission. Vehicles accessing road-side units have a few seconds to download information and experience a high packet loss rate. Hence, this paper proposes Cooperative Error Control (CEC) mechanism combining Cognitive Technology (CT) for video st...

In this paper, we introduce an efficient and trustworthy conditional privacy-preserving communication protocol for VANETs based on proxy re-signature. The proposed protocol is characterized by the Trusted Authority (TA) designating the Roadside Units (RSUs) to translate signatures computed by the On-Board Units (OBUs) into one that are valid with respect to TA’s public key. In addition, the pro...

With many advances in sensor technology and the Internet of Things, Vehicle Ad Hoc Network (VANET) is becoming a new generation. VANET’s current technical challenges are deploying decentralized architecture protecting privacy. Because Blockchain features decentralized, distributed, mass storage, non-manipulation features, this paper designs using called Blockchain-based VANET. VANET can effecti...

1. Carbon fiber multibarrel glass microelectrodes were used to record extracellular single-unit activity during microiontophoretic application of gamma-aminobutyric acid (GABA) or bicuculline methiodide (BMI) onto layer IV barrel neurons in the somatosensory cortex of fentanyl-sedated rats. Excitatory and inhibitory aspects of the neurons' receptive fields were quantified with the use of contro...

Vehicular ad hoc Networks (VANETs) enable vehicles to communicate with each other as well as with roadside units (RSUs). Although there is a significant research effort in radio channel modeling focused on vehicle-to-vehicle (V2V), not much work has been done for vehicle-to-infrastructure (V2I) using 3D ray-tracing tools. This work evaluates some important parameters of a V2I wireless channel l...

With the development of internet vehicles, traditional centralized content caching mode transmits through core network, which causes a large delay and cannot meet demands for delay-sensitive services. To solve these problems, on basis vehicle we propose an edge collaborative scheme. Road side unit (RSU) mobile computing (MEC) are used to collect information, predict cache popular content, there...
