Título da dissertação: “A CONTAINER-BASED ARCHITECTURE TO PROVIDE SERVICES FROM SDR DEVICES”
Resumo:
“Software Defined Radio is a programmable radio device which, when connected to a computer or as an embedded solution, it’s able to transmit and receive data informa- tion using radio waves. The programming features of SDR and it’s RF bandwidth range extends the application possibility to several areas including aviation, satellite, radar, and mobile communication. SDR has drawn great attention to network service provision. Act- ing as an multi-programmable air interface at the edge of wired network environments, SDR can receive, decode and forward radio information which is used to generate the services. Examples of services including real-time flight tracker web pages, and sen- sor monitoring data charts. However, to provide network services, SDR must integrate into complex network environments where recent technologies, such as NFV, SDN, con- tainerization and cloud computing, are applied. This thesis addresses the integration of SDRs with container virtualization for service provision. It proposes an easy-to-deploy container-based architecture to provide network services from SDR devices. Using dif- ferent types of SDR devices (USRP, LimeSDR and RTL-SDR), GNURadio platform and Docker Container, two use cases of proposed architecture are presented, demonstrating scenarios where ADS-B and LoRa communication are implemented in order to provide services to end users. Evaluation of proposed solution is performed comparing two mod- els of service provision: with the proposed architecture (two levels of network isolation), and without the architecture. The overhead time added to launch the services, the time response and computational resources utilization are compared, showing that there is an overhead added by the architecture which impacts on system performance. The overhead increases with the applied network isolation level. Conversely, the architecture converts the service functional components in modular components, its application can be extended to different RF projects, and offers non-functional benefits such as, real-time capability, SDR portability, scalability, network isolation, fine setting of communication parame- ters, and a set of control and configuration features inherited from container virtualization platform.
