Vehicular ad hoc networks (VANETs) have become increasingly common in recent years due to their critical role in the field of smart transportation by supporting Vehicle-to-Vehicle and ...Vehicle-to-Infrastructure communication. The security and privacy of VANET are of the utmost importance due to the use of an open wireless communication medium where messages are exchanged in plain text, something which allows attackers to intercept, tamper, replay, and delete them. Hence, there is a high probability that the safety of a VANET-based smart transportation system could be compromised. Nowadays, securing and safeguarding the exchange of messages in VANETs is the focus of many security research teams, as reflected by the number of authentication and privacy schemes that have been proposed. However, these schemes have not fulfilled all aspects of the security and privacy requirements. The present paper is an effort to provide a thorough background on VANETs and their components; various types of attacks on them; and all the security and privacy requirements for authentication and privacy schemes for VANETs. This paper is among the first to provide a comprehensive survey of the existing authentication and privacy schemes and compare them based on all security and privacy requirements, computational and communicational overheads, and the level of resistance to different types of attacks. It also provides a qualitative comparison with the existing surveys. This paper could serve as a guide and reference in the design and development of any new security and privacy techniques for VANETs.
The commercial adaptation of Vehicular Ad hoc NETwork (VANET) to achieve secure Intelligent Transportation System (ITS) heavily depends on the security guarantees for the end-users and consumers. ...Current VANET security standards address most of the security challenges faced by the vehicular networks. However, with the emergence of 5th Generation (5G) networks, and the demand for a range of new applications and services through vehicular networks, it is imperative to integrate 5G and vehicular networks. To achieve a seamless integration, various design and implementation issues related to 5G and VANETs must be addressed. We focus on the security issues that need to be considered in order to enable the secure integration of 5G and VANETs. More precisely, we conduct in-depth study of the current security issues, solutions, and standards used in vehicular networks and then we identify the security gaps in the existing VANET security solutions. We investigate the security features of 5G networks and discuss how they can be leveraged in vehicular networks to enable a seamless and efficient integration. We also propose a security architecture for vehicular networks wherein the current VANET security standards and 5G security features coexist to support secure VANET applications. Finally, we discuss some future challenges and research directions for 5G-enabled secure vehicular networks.

Existing conditional privacy-preserving authentication schemes utilized in Vehicular Ad-hoc Networks (VANETs) to satisfy security and privacy requirements essentially depend on point multiplication ...operations. Achieving repaid verification method of the message is commonly suffer performance efficiency from resulting overheads. We propose a conditional privacy-preserving authentication scheme to secure communication and perform better performance efficiency in this article. The proposed scheme only depends on an elliptic curve cryptography (ECC) based on a point addition operation instead of a point multiplication operation during signing and verifying messages. In the joining phase of the proposed scheme, the vehicle requires the joining process for the broadcasting traffic-related message to others or nearby RSU within its communication range. After obtaining the pseudonym and secret key from RSU, the vehicle is considered as a registered node in VANET. This article utilizes a Burrows-Abadi-Needham (BAN) logic to evidence that the proposed scheme fulfill successfully mutual authentication. The formal security phase shows that security and privacy requirements are satisfied by the proposed scheme. The performance efficiency shows that our proposed scheme has lower overhead in terms of computation cost compared with other recent schemes since a point multiplication operations based o ECC are not used. Therefore, the computation costs of the message signing, individual-authentication and batch-authentication in our proposed scheme are decreased by 99.3%, 99.7% and 98.1%, respectively.

Vehicular ad hoc networks (VANETs) are classified as an application of mobile ad hoc network (MANET) that has the potential in improving road safety and in providing travellers comfort. Recently ...VANETs have emerged to turn the attention of researchers in the field of wireless and mobile communications, they differ from MANET by their architecture, challenges, characteristics and applications. In this paper we present aspects related to this field to help researchers and developers to understand and distinguish the main features surrounding VANET in one solid document, without the need to go through other relevant papers and articles starting from VANET architecture and ending up with the most appropriate simulation tools to simulate VANET protocols and applications.
There has been a significant growth in the number of private automobiles in the previous decade as a result of technological advancements and changes in people’s lifestyles. This creates a major ...problem of congestion main reason being the transportation infrastructure’s inadequately construction and maintenance, which is the case in most major cities. By broadcasting the vehicle’s current location and surroundings in real time to other adjacent cars and roadside devices, VANETs may help alleviate traffic congestion by using intelligent algorithms to anticipate and avoid potential bottlenecks on the route. This can also be used to predict the shortest path from initial location to destination making it easy for the drivers in the choosing the right path. To implement all these functionalities, we need a robust and secure communication channel and also an intelligent and complex algorithm. Our aim is to predict a lane with least probability of accidents and find the shortest path with least travelling time and congestion. This keeps the user informed regarding the surrounding scenario’s and makes more coordinated, safer, and optimal use of transport networks.
The reliability of the communication link is quite common and challenging to handle as the topology changes frequently in vehicular ad hoc networks (VANETs). Another problem with VANETs is that the ...vehicles are from different manufacturers. Hence, the heterogeneity of hardware is obvious. These heterogeneity and reliability problems affect the message dissemination in VANETs. This paper aims to address these challenges by proposing a robust routing protocol capable of ensuring reliable, scalable, and heterogeneity-tolerant message dissemination in VANETs. We first introduced a hybrid hierarchical architecture based on software-defined networking (SDN) principles for VANETs, leveraging SDN's inherent scalability and adaptability to heterogeneity. Further, a road-side unit (RSU)-assisted cloud-based location-aware hybrid routing for software-defined VANETs (SD-VANETs) that we call RC-LAHR was proposed. RC-LAHR was rigorously tested and analyzed for its performance in terms of packet delivery ratio (PDR) and end-to-end delay (EED), along with a comprehensive assessment of network traffic and load impacts on cloud infrastructure and RSUs. The routing protocol is compared with state-of-the-art protocols, Greedy Perimeter Stateless Routing (GPSR) and Opportunistic and Position-Based Routing (OPBR). The proposed routing protocol performs well as compared to GPSR and OPBR. The result shows that the EED is reduced to 20% and the PDR is increased to 30%. The network reliability is also increased up to 5% as compared to the OPBR and GPSR.
The Smartphone VANET (Vehicle Ad-Hoc NETwork) is a novel idea to combat the issue of low hardware adoption for dedicated VANET hardware. However, there are many differences between the smartphone and ...the dedicated hardware it will replace. To account for these differences’ applications have to be designed specifically with the advantages and drawbacks of the smartphone in mind, especially in the case of safety applications. To this end an Emergency Electronic Brake Light (EEBL) application has been developed for the Smartphone VANET (SVANET) to test the feasibility of safety applications on the SVANET. In this paper, we test the EEBL application in a simulation environment, and present the preliminary results.
In vehicular ad hoc networks (VANETs), efficient message dissemination is critical to road safety and traffic efficiency. Since many VANET-based schemes suffer from high transmission delay and data ...redundancy, the integrated VANET-cellular heterogeneous network has been proposed recently and attracted significant attention. However, most existing studies focus on selecting suitable gateways to deliver safety message from the source vehicle to a remote server, whereas rapid safety message dissemination from the remote server to a targeted area has not been well studied. In this paper, we propose a framework for rapid message dissemination that combines the advantages of diverse communication and cloud computing technologies. Specifically, we propose a novel Cloud-assisted Message Downlink dissemination Scheme (CMDS), with which the safety messages in the cloud server are first delivered to the suitable mobile gateways on relevant roads with the help of cloud computing (where gateways are buses with both cellular and VANET interfaces), and then being disseminated among neighboring vehicles via vehicle-to-vehicle (V2V) communication. To evaluate the proposed scheme, we mathematically analyze its performance and conduct extensive simulation experiments. Numerical results confirm the efficiency of CMDS in various urban scenarios.
Setting up the physical parameters of a simulator is key to achieving realistic results. Setting those parameters requires an understanding of how they affect the simulation results. Packet loss is a ...key performance metric in communication and networks fields. In this paper, we present an overview of how Veins VANET simulator simulates WiFi packet loss. This work explains the physical parameters set by the user in Veins and how Veins then uses these parameters to simulate the effects of attenuation and packet loss.
