This paper introduces an efficient and spontaneous privacy-preserving protocol for vehicular ad-hoc networks based on revocable ring signature. The proposed protocol has three appealing characteristics: First, it offers conditional privacypreservation: while a receiver can verify that a message issuer is an authorized participant in the system only a trusted authority can reveal the true identi...

There is great concern over growing road accidents and associated fatalities. In order to reduce accidents, improve congestion and offer smooth flow of traffic, several measures, such as providing intelligence to transport, providing communication infrastructure along the road, and vehicular communication, are being undertaken. Traffic safety information broadcast from traffic lights using Visi...

Driven by both safety concerns and commercial interests, popular content distribution (PCD), as one of the key services offered by vehicular networks, has recently received considerable attention. In this paper, we address the PCD problem in highway scenarios, in which a popular file is distributed to a group of onboard units (OBUs) driving through an area of interest (AoI). Due to high speeds ...

Car-2-Car communication requires the use of pseudonymous public keys to ensure the vehicle’s privacy by making its messages unlinkable over a longer period. The Pseudonymous PKI (PPKI) for Ubiquitous Computing by K. Zeng [Ze06] offers peer-side pseudonym generation, non-repudiation and an efficient revocation mechanism that excludes the revoked peers from the group of authorized participants. I...

In recent years, vehicular ad-hoc networks (VANETs) is one of the rapid growing technology to form a network of vehicles and between vehicles and roadside units (RSUs) to provide a variety of services like safety, traffic efficiency and infotainment information to its drivers and passengers. In this paper, we have considered the communications are from V2I, I2V, I2I and on the basis of scheduli...

Vehicular AdhocNETworks (VANETs) relies on continuous data exchange among vehicles and vehicles to roadside units (RSU) to aid road safety, route planning, etc. A transition from free flow to congested traffic on highways often spontaneously originates, despite the fact that the road could satisfy a higher traffic demand. The reasons for such a traffic breakdown are perturbations caused by huma...

In this paper, an approach for suitable fault management in traffic information networks, focusing on the isolation of network faults in infrastructure networks, will be introduced. We will show, that modelbased diagnosis is an efficient method for finding explanations consisting of the underlying fault events of system failures. A fault management system based on these concepts will be discuss...

The Internet of Vehicles (IoV) is an emerging paradigm, which expected to be integral component beyond-fifth-generation and sixth-generation mobile networks. However, the processing requirements strict delay constraints IoV applications pose a challenge vehicle units. To this end, multi-access edge computing (MEC) can leverage availability resources at network meet intensive computation demands...

Many researchers have failed to utilize back-calculation to estimate traffic emissions effectively or have obtained unclear results. In this study, the back-calculation of traffic-related PM10 emission factors based on roadside concentration measurements was analyzed. Experimental conditions were considered to ensure the success of back-calculation. Roadside measurements were taken in a street ...
