Adaptive IDS for Cooperative Intelligent Transportation Systems Using Deep Belief Networks July 31, 2022, 11:42 a.m.
Vehicles connected to cITS form vehicular ad hoc networks (VANET) to exchange messages. Like other networks and systems, cITSs are targeted by attackers intent on compromising and disrupting system integrity and availability. They can repeatedly spoof false information causing bottlenecks, traffic jams and even road accidents. The existing security infrastructure assumes that the network topology and/or attack behavior is static. However, the cITS is inherently dynamic in nature. Moreover, attackers may have the ability and resources to change their behavior continuously. Assuming a static IDS security model for VANETs is not suitable and can lead to low detection accuracy and high false alarms. Therefore, this paper proposes an adaptive security solution based on deep learning and contextual references that can cope with the dynamic nature of the cITS topologies and increasingly common attack behaviors.

Interpretation and Investigations of Topology based  Routing Protocols applied in VANET July 3, 2022, 3:08 p.m.
To improve VANET performance there are several routing protocols which may enable packet transport from the source node to the destination node. The prior objective of this research is to select and suggest reliable routing protocol for VANET’s implementation. This research presents the overall investigation and interpretation of routing protocol based on topology i.e., AODV, OLSR, DSR, and DSDV on the grounds of simulation parameters (packet delivery ratio, overhead, throughput). The performance and effects of routing protocols has been evaluated through the use of network simulator (NS-3) and mobility simulator (SUMO).
M.Tech Thesis Help in VANET July 3, 2022, 3:03 p.m.
VANET calls for an ad hoc network of vehicles. A Vehicle Ad-Hoc Network or VANET is a sub-form of a Mobile Ad-Hoc Network or MANET that provides connectivity between vehicles and between vehicles and base stations on the road to ensure efficient and safe transport. VANET’s aim is to turn the conventional transport system into a smart transport system. If it does not depend on pre-existing infrastructures like routers etc. in wired networks, a network is ad hoc.
VANET’s To Become Key Drivers Of Next Gen ITS July 3, 2022, 2:51 p.m.
The use of intelligent transport systems, systems designed to enhance and improve transportation and transit through the application of data and communications technology, has slowly but steadily begun to pick up pace throughout the world over the past few years. This is mainly due to advances in wireless and vehicular communications technology that allow data to be collected and shared among vehicles and infrastructure. In particular, the field of vehicular ad hoc networks (VANET’s) is the subject of significant and growing interest due to the maturing of technologies that enable its application within intelligent transportation systems. In this article, we’ll be looking at what VANET’s are as well as how they work and what their applications and benefits are.

Certificate Management Scheme for VANETs Using Blockchain Structure June 30, 2022, 9:16 p.m.
A critical aspect of VANETs is providing privacy for the vehicles. The employment of pseudonym certificates is a well-known solution to the privacy problems in VANETs. However, certificate management faces challenges in renewing certificates and revoking vehicles. The centralized certificate management, especially resulting in the delay of the revocation process, harms the nodes of VANETs. This paper proposes a blockchain structure-based certificate management for VANETs and voting-based revocation to halt misbehaving vehicles’ actions. Moreover, this paper presents extended privacy for the participants of the voting process using ring signatures.
Secure and Efficient Communication in VANETs Using Level-Based Access June 25, 2022, 4:46 p.m.
In recent years, the development of vehicular ad-hoc networks (VANETs) has received much attention in intelligent transportation systems (ITS). Unlike traditional ad-hoc networks, VANETs are emerging with unique characteristics that share similar technology with autonomous vehicles (AVs) and automated driving systems (ASDs). Communication between vehicles and the surrounding infrastructure unit, such as a roadside unit (RSU), must be secured, concise, and authentic. Hence, an access control system for the ad-hoc environment is required.
State-of-the-art approach to clustering protocols in VANET June 25, 2022, 4:43 p.m.
Vehicular ad hoc network (VANET) assists in improving road safety, traveller comfort, and intelligent transportation systems to a great extent. Dedicated short-range communications technology is specially designed for VANET to form communication among vehicles and vehicles to infrastructure. The lack of router devices in the flat vehicle-to-vehicle network structure of VANET may raise complicated issues like scalability, resource scarcity, reliability, and hidden terminal problem inside the network. The concept of vehicle clustering is introduced in VANET to improve network performance by handling all such issues.
A hybrid optimization with ensemble learning to ensure VANET network stability based on performance analysis June 25, 2022, 4:39 p.m.
High vehicle mobility, changing vehicle density and dynamic inter-vehicle spacing are all important issues in the VANET environment. As a result, a better routing protocol improves VANET overall performance by permitting frequent service availability. Therefore, an ensemble-based machine-learning technique is used to forecast VANET mobility. Effective routing based on a hybrid metaheuristic algorithm combined with Ensemble Learning yields significantly improved results. Based on information collected from the Road Side Unit (RSU) or the Base Station, a hybrid metaheuristic (Seagull optimization and Artificial Fish Swarm Optimization) method is used to estimate (BS). The suggested approach incorporates an ensemble machine learning and hybrid metaheuristic method to reduce the latency.
