Designing a reliable fiber optic communication network is crucial. High-speed optical networks are now a vital part of the communication system and the foundation of wireless and mobile networks, driven by their constant expansion and increasing demand. The high transmission rate improves spectral utilization, increases system capacity, and reduces overall system expenditure. To improve the communication channel and achieve high transmission performance and data rates, a spread-spectrum compensation scheme is required. The goal of fiber optic communication systems is to transmit as many bits per second as possible over the longest possible distance at an acceptable data rate. Two methods are... More >

The Internet of Vehicles (IoV) is a core component of smart transportation systems, making it feasible to exchange information among vehicles, infrastructure, and central systems in real time. However, the effective use of resources and the efficient distribution of tasks in these dynamic environments is a challenging task. This paper presents a blockchain-based collaborative task allocation framework method that can solve these problems by using a greedy algorithm for general task allocation and adopting a dynamic collaboration scheduling algorithm for emergent tasks. Employing the blockchain-based reward mechanism, the transparency, fairness, and security in dynamic mobile crowdsensing (MC... More >

The Internet of Vehicles (IoVs) is an emerging technology that enhances transportation systems by enabling interactions between vehicles, infrastructure, and other entities. Securing IoV networks from cyber threats like eavesdropping, data tampering, and intrusions is a major challenge. This research presents a Blockchain-Enabled Secure Authentication Protocol for IoVs (BESA-IOV), which leverages blockchain’s decentralized and tamper-resistant nature for secure communication in vehicular networks. By utilizing ECC-based lightweight cryptography and blockchain-based public key management, it ensures strong authentication, confidentiality, and integrity. The results show that BESA-IOV signif...
