Advancement in wireless communication technology along with the evolution of low power computational devices, have given rise to Internet things paradigm. This paradigm is transforming conventional VANETs into Internet-of- vehicles. transition has led a substantial commercial interest; as result, there been significant boost field vehicles during past few years. IoV promises wide range applicat...

This paper proposes a novel bilinear pairing-free identity-based privacy-preserving anonymous authentication scheme for vehicle-to-vehicle (V2V) communication, called “NIBPA”. Today, vehicular ad hoc networks (VANETs) offer important solutions traffic safety and efficiency. However, VANETs are vulnerable to cyberattacks due their use of wireless communication. Therefore, schemes used solve secu...

Vehicular ad-hoc networks (VANETs) form when vehicles are equipped with devices capable of short-range wireless communication. Accurate simulation of VANETs is a challenging task, requiring both a vehicle mobility model and a network simulator. Although separate simulators exist, integrating them is difficult. We have developed an integrated simulator, based on studied, validated models. We arg...

Vehicular Ad-Hoc Networks (VANETs) require advanced cryptographic techniques in order to meet the conflicting requirements of simultaneous user anonymity and accountability. In this paper, we present a novel group signature scheme that meets these requirements. It provides constant-time revocation, much more efficient than what is achieved in existing schemes. It also provides exculpability so ...

Geonetworking and the corresponding routing protocols play an important role in application of Vehicular Ad-hoc Networks (VANETs). This paper presents the architecture and implementation of CLWPR (Cross-Layer, Weighted, Position-based Routing), a position-based routing protocol optimized for VANETs in NS-3 simulation environment. It utilizes mobility information from nodes and cross-layer infor...

Vehicular ad hoc networks (VANETs) have great potential to improve road safety and increase passenger convenience in vehicles. On the other hand, since they use an open medium for communication, they are exposed to several threats that influence the reliability of these features. This work presents a modular cross layer intrusion detection approach as a method to increase security in VANETs. Th...

With the advances in the development of embedded technology, wireless communication and VANETs, and the awareness that vehicles possess a vast amount of unused resources, new services and applications have been proposed recently. The emphasis of this paper is on describing an idea, related work, and open research challenges of using parked vehicles as a spatio-temporal distributed storage syste...

In Vehicular Ad hoc Networks (VANETs), vehicles periodically broadcast messages for every 100 to 300 milli seconds. Such messages are used to report a safety or non-safety application. Authentication on such safety messages assures the end users in the network. However, a malicious vehicle can trace the messages and can launch varied types of malicious activity which leads to the compromise of ...

Message routing in vehicular ad hoc networks (VANETs) pose a particular technical challenge due to their highly dynamic nature. Eiza and Ni [1] have proposed an evolving graph approach to route messages in VANETs both reliably and efficiently. Evolving graphs, however, are resource intensive and do not scale well as the density of vehicles in the network increases. In this paper, we present a h...

In Vehicular Ad-hoc Networks (VANET), vehicles act like mobile nodes for fetching, sharing, and disseminating important information related to vehicle safety, warning messages, emergency events, passenger infotainment. Due continuous sharing of with their surrounding nodes, Road Side Units (RSUs), infrastructures, the existing host-centric IP-based network cannot fulfill requirements VANETs. Th...
