I9VANET: um modelo de arquitetura de software para rede veicular em nuvem

Abstract

As a result of population growth, large cities face daily problems related to urban mobility such as congestion, poor quality of roads, ineffciency of public transportation, among others. Intelligent Transport Systems (ITS) initiatives act as an effcient solution to improve the functioning and performance of fraffc systems, reducing congestion and increasing safety for citizens. Currently, researchers have been searching the ad-hoc vehicular networks (VANET) for a possible solution to the problems related to urban mobility. However, VANET still has a number of challenges that must be addressed in order for its use to be consolidated. In this way, the present work shows an architecture called I9VANET, whose intention is the management of a vehicular network in a virtualized way through cloud computing, to assist in the solutions of the main challenges related to VANET such as: interference in communication due to trees and buildings; High node mobility; High and low density of nodes in an area; Guarantee of confidentiality, integrity and availability, authenticity and non-repudiation. After conducting experiments in the laboratory, it was verified the technical viability for the use of defined speeds for 3G, 4G and 5G mobile telephony models, satisfying the effciency criteria when compared to other works in the literature, which used Ad- Hoc.
