Resumo: With the growth in the number of wireless devices, spectrum scarcity has become an issue. Faced with this problem, many regulatory agencies around the world studied new ways to increase the spectral efficiency of radio frequency bands. Among the alternatives, the dynamic spectrum access is made possible by a database and also the use of opportunistic access techniques through spectrum sensing. However, it is known that these individual models may not lead to the maximum possible efficiency, or even, they may not ensure proper safety for primary users. Aiming to solve these problems, this work brings a study with the idealization of a spectrum sensing infrastructure based on IoT networks, which associated with a database, provides all the necessary tools for spectrum management, enabling opportunistic secondary networks, ensuring users security, greater accuracy and reliability on spectrum usage, as well as a spectrum market among users based on a smart contract. In this conception, the most conservative approach using a database works in conjunction with the proposed infrastructure for the sensing network, intending to keep up to date with the most accurate information on spectrum occupation in real-time.

Diante deste problema, muitos ??rg??os reguladores pelo mundo come??aram a estudar novas formas de aumentar a efici??ncia espectral das bandas de r??dio-frequ??ncia. Dentre as alternativas encontram-se o acesso din??mico ao espectro viabilizado por base de dados e tamb??m o uso de t??cnicas de acesso oportunista atrav??s de sensoriamento espectral. No entanto, ?? conhecido que esses modelos individualmente podem n??o levar ?? m??xima efici??ncia poss??vel, ou ainda, podem n??o assegurar a devida seguran??a aos usu??rios prim??rios. Buscando resolver esses problemas, este trabalho traz um estudo com a idealiza????o uma infraestrutura de sensoriamento espectral baseada em redes IoT, que associada com uma base de dados, prov?? todas as ferramentas necess??rias para ger??ncia do espectro, habilita????o de redes secund??rias oportunistas, garantia da seguran??a dos usu??rios, maior precis??o e confiabilidade sobre a ocupa????o do espectro, al??m de um mercado de espectro entre os usu??rios baseado em contrato inteligente. Nesta concep????o, a abordagem mais conservadora com uso de base de dados funciona em conjunto com a infraestrutura proposta para rede de sensoriamento, buscando manter-se atualizada com a mais precisa informa????o da ocupa????o do espectro em tempo real.Submitted by Tede Dspace (tede@inatel.br) on 2021-03-08T20:02:24Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) Disserta????o V.
