Abstract(s)
A manutenção de veículos aéreos não tripulados, em inglês Unmanned Aerial Vehicle (UAV) e também conhecidos como drones, depende em grande parte do controlo remoto. O alcance da operação é limitado pelo sucesso das comunicações via rádio entre o controlador e o UAV. De forma a expandir esse alcance, podem ser utilizadas redes ou enxames de UAVs de modo a definir uma mesh com o objetivo de se poder encaminhar comandos de controlo para unidades mais distantes. Devido aos obstáculos naturais e artificiais que existem no nosso meio ou então devido a interferências intencionais, a comunicação entre os drones é suscetível a interrupções e nesse sentido, é necessário criar soluções que consigam optimizar a comunicação evitando ao máximo as interrupções que possam ocorrer devido aos obstáculos de tal forma que é importante avaliar os diversos protocolos de encaminhamento sejam eles ao nível de Internet Protocol (IP) ou então mais baseados numa camada inferior, como o Multiprotocol Label Switching (MPLS), tirando mais partido das redes de operador de telecomunicações. Ao longo desta tese é proposta uma especificação, desenvolvimento e teste de um protocolo de sobreposição para encaminhar instruções do controlador para comandar um UAV remoto numa base multi-hop, tendo em atenção as vantagens que oferecem os diferentes tipos de encaminhamento em cenários de conectividade de UAVs para trocas de volumes consideráveis de informação.
The maintenance of unmanned aerial vehicles, commonly called UAV, depends on the remote control. The scope of operation is limited by the success of radio communications between the controller and the UAV. In order to expand this range the UAVs networks or swarms can be used in order to define a mesh so that control commands can be routed to more distant units. Due to the natural and artificial obstacles that exist in our environment or due to intentional interference, the communication between drones is susceptible to interruptions and in this sense, it is necessary to create solutions that can optimize the communication avoiding as much as possible the interruptions that may occur due to obstacles in such a way that it is important to evaluate the various routing protocols, be they at the IP level or more based on a lower layer, such as MPLS, taking more advantage of the telecommunications operator networks. Throughout this thesis a specification, development and testing of an overlay protocol for routing controller instructions to command a remote UAV on a multihop basis is proposed, taking into account the advantages offered by different types of routing in UAV connectivity scenarios for exchanges of considerable volumes of information.
