Many Vehicular Ad Hoc Networks (VANETs) applications require the vehicle's location information to be available at anytime and anywhere within the network. Vehicle-to-vehicle (V2V) communication allows the exchange of mobility data, which includes position, speed and heading information, that can be used for location estimation. However, if the exchanged mobility data contains invalid or wrong information,...
VANETs are a kind of adhoc wireless network, which is characterised as restricted topology patterns, node mobility and dynamic in nature. Vehicles communicate with each other via Vehicle-to-Vehicle (V-to-V), Vehicle to roadside unit (RSU) and RSU to Base-Station. Every vehicle is equiped with on board unit (OBU) that helps to communicate with RSU and Base-Station. Routing is very important in communication...
In this paper we propose a security system to protect external communications for self-driving and semi self-driving cars. The proposed system can detect malicious vehicles in an urban mobility scenario. The anomaly detection system is based on fuzzy petri nets (FPN) to detect packet dropping attacks in vehicular ad hoc networks. The experimental results show the proposed FPN-IDS can successfully...
Intended for providing the security in the VANETS (Vehicular Ad hoc Network) scenario, the covert storage channel has been implemented through which data transmitted between the sender and the receiver. Covert channels are the logical link which be used for the communication purpose and hide the secure data from the intruders. This paper refers to the Establishment of bit selective mode covert storage...
An ad hoc network is a suburbanized types of wireless network. The ad hoc which means “for this purpose” formed network instantly when nodes are connected in network for communication. Ad hoc network is a temporary network built for specific purpose. It does not require any pre-established infrastructure. The dynamic nature of ad hoc networks makes them more utilisable. On the other hand, selfish...
Vehicular ad hoc networks play an important role in the success of a new class of vehicles, i.e. self-driving and semi self-driving vehicles. These networks provide safety and comfort to passengers, drivers and vehicles themselves. These vehicles depend heavily on external communication to predicate the surrounding environment through the exchange of cooperative awareness messages (CAMs) and control...
Data routing has gained great intention since the appearance of Vehicular Networks (VANETs). However, in the presence of attackers, reliable and trustworthy operations in such networks become impossible without securing routing protocols. In this paper, we target to study and design a secure routing protocol S-GyTAR for vehicular environments. Several kinds of routing techniques are proposed in the...
Recent developments in wireless communication technologies led to the evolution of Vehicular Ad hoc Network (VANET). The main goal of VANET is to afford communication between vehicles without negotiating security. Regulating the traffic and identifying malicious vehicles plays an important role in VANET. In this paper, traffic control is achieved by sustaining the distance between the vehicles and...
Vehicular Ad Hoc Network (VANET) is a challenging area of research in the field of vehicular technology. It is an emerging topic for its high mobility and high link disruption. But if link disruption is due to the malicious drivers in the network then it reduces the performance of the network. Hole Generation attack is a kind of attack in which the malicious drivers breaks the communication links...
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...
An ad hoc network is a kind of wireless network without centralized administration or fixed network infrastructure, in which nodes perform routing discovery and routing maintenance in a self-organized way. Currently, many people focus on the routing protocol in ad hoc networks. But few people research how to detect the validity of the data fusing without large communication overhead. In this paper,...
