VANET security introduces significant processing overhead for resource-constrained On-Board Units (OBUs). Here, we propose a novel scheme that allows secure Vehicular Communication (VC) systems to scale well beyond network densities for which existing optimization approaches could be workable, without compromising security (and privacy).
Recently, Vehicular Cloud Computing (VCC) are promising to convey relatively more communication, on-demand and based on pay-as-you-go fashion. Such environment concept's is being widely adopted, which is resulting in several research issues and challenges. Privacy, service cost and provisioning delay are identified as the most crucial challenges to be addressed. This paper extends our previous work...
Vehicular Delay Tolerant Networking (VDTN) is a special instance of Vehicular Ad hoc Networking (VANET) and in particular Delay Tolerant Networking (DTN) that utilizes infrastructure to enhance connectivity in challenged environments. While VANETs assume end-to-end connectivity, DTNs and VDTNs do not. Such networks are characterized by dynamic topology, partitioning due to lack of end-to-end connectivity,...
Vehicular networks are seen as the basis for the development of intelligent transportation systems. Therefore, and in order to take advantage of the benefits from these transportation systems, the development of standards that meet the specific characteristics of vehicular networks was required. The "Wireless Access in Vehicular Environments" (WAVE) was developed in order to fulfill this...
Plug-in Electric Vehicles (PEVs) are expected to be widely utilized in the near future if issues related to the availability of charging infrastructure are resolved and if PEVs are efficiently integrated with the smart grid. The Vehicle-to-Grid (V2G) system is an emerging technology that enables the communication and control between PEVs and the smart grid. This promising concept is designed to provide...
Automotive industry is about to make a cutting-edge step in terms of vehicular technologies by letting vehicles communicate with each other and create an Internet of Things composed by vehicles, i.e., an Internet of Vehicles (IoV). In this context, information dissemination is very useful in order to support safe critical tasks and to ensure reliability of the vehicular system. However, the industrial...
In existing trust establishment researches, the decision making accuracy and decision delay of received event message are both the outstanding problems in VANETs. Especially on the decision delay, the delay of alert event might lead to traffic accident and injury. In this paper, we propose an adaptive decision making model which can make decision quickly by the effective and quick assistance of the...
In this work, we present a analytical hierarchy process (AHP) for computing trust in the vehicular ad hoc networks (VANETs). AHP based trust management provides a lightweight security alternative to existing security techniques. Trust Management in VANETs is required to broadcast of selfish or malicious messages and also enable other vehicles to filter out such messages. A trust management system...
Intelligent transportation systems (ITS) include a broad variety of means of transportation and a broad variety of usage scenarios and user preferences and interests. To avoid a waste of spectrum and to keep deployment cost low, a combination of existing networks and infrastructure components especially dedicated to the ITS will built an ITS. As existing networks and new usage scenarios need to be...
Vehicular Ad Hoc Network (VANET) is an emerging area of research to provide Intelligent Transportation System (ITS) services to the end users. It is a challenging topic for its high mobility and frequent link disruption. Recently researchers are working on many specific issues related to VANET like routing, broadcasting, Quality of Service (QoS), security, architectures, applications, protocols, etc...
