Resumo: | Vehicular Ad hoc Networks (VANETs) support the development of safety and infotainment applications, allowing vehicles to communicate between each other and with the infrastructure, assuring their connection and of its occupants to the Internet. These VANETs may rely on different technologies for their deployment such as IEEE 802.11p (WAVE) or IEEE 802.11a/g/n (Wi-Fi), but even then complete coverage and full connectivity may not be assured. Therefore, this dissertation has the main objective of creating the necessary network mechanisms to allow the VANET, with mobility and multihoming support, to make use of an additional communication interface via commercial cellular networks, increasing its availability. The work developed in this dissertation has allowed the integration of a commercial cellular network in the inter-technology mobility mechanisms available in the vehicular network, that served as the base work for this project. The implementation of the integration of a cellular solution allows the vehicles to maintain communication to the Internet through the VANET, even when there is no available connection through mainstream VANET technologies, such as IEEE 802.11p. The proposed solution uses commercial cellular networks without the need of any contribution by the network providers and maintaining transparency to the end-user. The implemented approach was evaluated with real systems in laboratory and real-world scenarios, in order to evaluate the performance of the proposed solution. The obtained results show that with the cellular solution it is, in fact, possible to maintain connectivity to the VANET, but in high traffic tests the cellular network starts to underperform. Nevertheless, it was possible to validate the correct execution of the VANET with the cellular solution, automatically reacting to the respective necessities to maintain connection between the vehicles and infrastructure, without the need of intervention by any external entity in the process. |

Estas redes veiculares podem depender de diferentes tecnologias para a sua implementação tais como IEEE 802.11p (WAVE), IEEE 802.11a/g/n (Wi-Fi), que mesmo assim podem não garantir uma cobertura plena e total conectividade. Desta forma, esta dissertação tem como principal objectivo a criação de mecanismos de rede necessários para dotar uma rede veicular, com suporte para mobilidade e multihoming, de uma interface de comunicação adicional que faz uso de redes celulares comerciais, aumentando assim a conectividade da mesma. O trabalho realizado ao longo desta dissertação permitiu a integração da rede celular comercial nos mecanismos de mobilidade inter-tecnologia presentes na rede veicular existente, que serviu de base para este projecto. A implementação da integração de uma solução celular permite que veículos mantenham comunicação de uma forma integrada com a Internet, mesmo quando não existe ligação disponível através das tecnologias de comunicação veiculares tradicionais, como o IEEE 802.11p. A solução proposta faz uso de redes celulares comerciais sem requerer contribuições da parte destas, e sendo completamente transparente para os utilizadores ligados à rede veicular. A solução desenvolvida foi avaliada em cenários de laboratório e em cenários reais com sistemas reais, que permitiram avaliar o desempenho da solução proposta. Os resultados obtidos demonstram que, com a solução celular é, de facto possível manter a conectividade à rede veicular, mas em testes de elevado tráfego, o desempenho da rede celular começa a deteriorar. Foi assim possível validar o correcto funcionamento da rede veicular com a solução celular, reagindo de forma autónoma às necessidades apresentadas de forma a manter ligação entre os veículos e a infraestrutura, sem necessidade de intervenção por parte de qualquer entidade externa.2019-122019-12-01T00:00:00Z2021-01-02T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/28615engRocha, Filipe Emanuel de Sáinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T11:55:21Zoai:ria.ua.pt:10773/28615Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:01:07.139050Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
