PROJECT TITLE :

A Novel Blockchain Based Secured and QoS Aware IoT Vehicular Network in Edge Cloud Computing

ABSTRACT:

An IoT (Internet of Things)-based vehicular ad-hoc network and a software-defined network are the two components that come together to form a software-defined vehicular network. Researchers are currently working on the VANET (Vehicular Ad-hoc Network) to improve the overall performance of the system in order to facilitate improved communication within IoT-based vehicle networks. Researchers have become increasingly interested in edge computing as a means of improving the performance and dependability of information applications running over ad-hoc networks like VANET. In the most recent research, cloud computing is utilized for the execution of message-related tasks; this results in an increase in response time. In this article, we propose a Software-defined Fault Tolerance and QoS-Aware (Quality of Service) IoT-Based Vehicular Networks Using Edge Computing Secured by Blockchain in order to decrease overall communication delay, message failure fault tolerance, and secure service provisioning for VANET ad-hoc networks. This will allow for a more efficient and secure provisioning of services. As a solution to the issues of response delay, message failure, fault tolerance, and security offered by the Blockchain, we proposed heuristic algorithms. The proposed model receives vehicle messages via SDN nodes, which are placed on nearby edge servers. The blockchain then validates the edge servers so that they can provide secure services to vehicles. The SDN controller, which is housed on an edge server and is located on the shoulder of the road in order to circumvent delays in communication, is in charge of receiving various messages from the vehicles and classifying these messages according to one of two distinct categories. The edge server is responsible for performing the message division by taking into consideration the time line, the size, and any urgent circumstances. The SDN controller was responsible for organizing these messages and delivering them to the appropriate location. Following the successful delivery of the message to its intended recipient, an error tolerance mechanism examines the acknowledgements received. The failure message will be resent by the fault tolerance algorithm in the event that the delivery of the message fails. The proposed model is put into action with the help of a specialized simulator, and the results are compared to the most recent VANET-based quality of service and fault tolerance models. Through the utilization of the edge server SDN controller, the performance of the suggested model was demonstrated, which resulted in a reduction of 55% in the overall message communication delay. This reduction applied to both routine and urgent messages. By utilizing the edge server, cloud server, and blockchain infrastructure, the proposed model cuts down on execution time while simultaneously lowering the security risk and the ratio of messages that fail to be delivered.
