Abstract
Vehicular Ad Hoc Networks (VANETs) are wireless communication networks specifically designed for vehicles on the road. VANETs enable vehicles to establish direct wireless connections with each other and with roadside infrastructure, creating a dynamic network for information exchange. This technology holds great promise for enhancing road safety, optimizing traffic flow, and enabling new applications in transportation systems. In VANETs, vehicles share real-time information such as position, speed, and acceleration, allowing for cooperative awareness and informed decision-making. Vehicular communication encompasses both Vehicle-to-Vehicle (V2V) communication and Vehicle-to-Infrastructure (V2I) communication, enabling vehicles to communicate with each other as well as with roadside units. VANETs face various challenges, including designing efficient routing protocols for dynamic network topologies, addressing privacy and security concerns, and ensuring interoperability among different systems.This thesis explores the realm of Vehicular Ad Hoc Networks with a focus on investigating the challenges, proposing solutions, and providing insights into future perspectives. In the field of VANETs, authentication faces challenges in securely managing vehicle identities and establishing trust without compromising privacy. Routing encounters issues related to the dynamic network topology, scalability, and the need for diverse Quality of Service (QoS) support. Meanwhile, security threats loom, including Denial-of-Service attacks, Sybil attacks, and concerns about message tampering. The delicate balance between ensuring location privacy and enabling location-based services further complicates security efforts. Addressing these issues necessitates the development of robust cryptographic techniques, efficient routing algorithms, and secure communication protocols to ensure the reliability and security of V2X communication in VANETs. Ongoing research is crucial to stay ahead of evolving threats in this dynamic and challenging vehicular environment. This thesis introduces a secure VANET framework that incorporates two candidate technologies: fog computing and software-defined networking Also, a routing framework is introduced which strengthens security by juxtaposing a novel cryptographic scheme elliptic curve integrated encryption scheme (ECIES) with DSDV, AODV, and OLSR routing protocols. Also, proposed intrusion detection system (IDS) to minimise the cybersecurity risks in the network. The simulation of the proposed methods was performed using OMNET++ and SUMO and performance was evaluated with several metrics. The experimental results showed that the proposed work achieved better results compared to existing research methods.
