The vision of the Internet of Vehicles (IoV) has acquired widespread acceptance as a result of the development of wireless technology. Its ability to provide drivers with various mobile services has made it an attractive application. Blockchain based security solution is considered good in various applications of IoV till now. But all the frameworks and architectures developed so far in IoV adopt the load of blockchain. So, it is generally deployed on or above edge computing devices, keeping lower structure of the frameworks traditional as managing blockchain with low computing devices on the physical layer is really a challenge. Securing communication in an IoV environment requires ensuring strong authentication and encryption. Although limited efforts are accessible for strong authentication and secure communication but, the lightweight characteristic is absent from this list. This article is proposing a lightweight secured framework for blockchain based IoV that offers strong authentication and secure communication. After securely authorization of the vehicle, it introduces the concept of branched blockchain taking into the consideration of most recently used block, so that the low powered devices can also adopt the security benefits of the blockchain. The existing mining systems are not designed to handle the needs of the IoV at the physical layer. Some of the key features of the proposed framework are lightweight blockchain for physical layer and above, load balancing, scalability, availability and decentralization. According to the relative research, which takes into account factors like computation and transmission costs, our suggested framework outperforms already implemented ones. This framework can act as base of new research verticals where anyone is looking forward for a lightweight blockchain variant applicable on physical layer of IoV.
The Internet of Vehicles (IoV) is a new paradigm for vehicular networks. Using diverse access methods, IoV enables vehicles to connect with their surroundings. However, without data security, IoV settings might be hazardous. Because of the IoV’s openness and self-organization, they are prone to malevolent attack. To overcome this problem, this paper proposes a revolutionary blockchain-enabled game theory-based authentication mechanism for securing IoVs. Here, a three layer multi-trusted authorization solution is provided in which authentication of vehicles can be performed from initial entry to movement into different trusted authorities’ areas without any delay by the use of Physical Unclonable Functions (PUFs) in the beginning and later through duel gaming, and a dynamic Proof-of-Work (dPoW) consensus mechanism. Formal and informal security analyses justify the framework’s credibility in more depth with mathematical proofs. A rigorous comparative study demonstrates that the suggested framework achieves greater security and functionality characteristics and provides lower transaction and computation overhead than many of the available solutions so far. However, these solutions never considered the prime concerns of physical cloning and side-channel attacks. However, the framework in this paper is capable of handling them along with all the other security attacks the previous work can handle. Finally, the suggested framework has been subjected to a blockchain implementation to demonstrate its efficacy with duel gaming to achieve authentication in addition to its capability of using lower burdened blockchain at the physical layer, which current blockchain-based authentication models for IoVs do not support.
It is difficult to run delay-sensitive applications and the cloud simultaneously due to performance metrics such as latency, energy consumption, bandwidth, and response time exceeding threshold levels. This is the case even though advanced networks and technologies are being used. The middleware layer of the Internet of Things (IoT) architecture appears to be a promising solution that could be used to deal with these issues while still meeting the need for high task offloading criterion. The research that is being proposed recommends implementing Fog Computing (FC) as smart gateway in middleware so that it can provide services the edge of the networks. Applications that are sensitive to delays would then be able to be provided in an efficient manner as a result of this. A smart gateway is proposed as solution for taking the offloading decision based on the context of data, which offers a hybrid approach in order to make decisions regarding offloading that are efficient and effective. A solution that uses machine-learning reasoning techniques to make offloading decisions, in multiple fog-based cloud environments. Feature selection, and classification are used as a learning method and are also ensembled as hybrid logistic regression-based learning to provide the best offloading solution. It works by learning the contextual information of data and identify the cases to make the decision of offloading. The proposed model offers a solution that is both energy and time efficient, with an overall accuracy of approximately 80 percent. With the proposed intelligent offloading approach, it is expected that Internet of Things applications will be able to meet the requirement for low response time and other performance characteristics.
