Abstract
The innovation in the Internet of Things (IoT) has amplified numerous time-bounded critical applications in different areas such as healthcare, banking, industries, product delivery services, and online food services. In this paper, an effort has been made an effort to propose a novel framework for critical services in Intelligent Transport systems (ITS). In ITS, critical services involve activities such as the exchange of information or transmission of data among vehicles, accessing of information in the case of accidents, determination of the best-routed route from the current location to a hospital, and determination of a low-congestion traffic route during working hours. The unavailability of any information leads to considerable loss of business, life, or property. This study aims to quantify the transportation service assurance by conceptualizing Service Level Agreements (SLAs) for various critical services, the energy requirement for complete data transmission, and providing Blockchain-enabled secured data transmission by calculating trust metrics of IoT nodes using a trust analyzer. In conclusion, the proposed mechanism is evaluated against various routing parameters by quantifying mean satisfied routes in ITS, throughput, delay, energy efficiency, trust in data transmission, and results with security configurations for tolerance toward attacks.
