Neste artigo, investigamos um sistema de comunicação cooperativo composto por uma origem, um destino e vários relés de decodificação e encaminhamento (DF) na presença de um potencial espião malicioso dentro ou fora da área de cobertura da fonte. Com base nos canais de desvanecimento Nakagami-m mais gerais, analisamos o desempenho de segurança dos esquemas de seleção de relé único e de seleção de múltiplos relés para proteger a fonte contra espionagem. No esquema de seleção de relé único, apenas o melhor relé é escolhido para auxiliar na transmissão da fonte. Diferentemente da seleção de relé único, o esquema de seleção de múltiplos relés permite que vários relés encaminhem a origem para o destino. Também consideramos a transmissão direta clássica como um esquema de referência para comparar com os dois esquemas de seleção de relés. Derivamos as expressões exatas de forma fechada de probabilidade de interrupção (OP) e probabilidade de interceptação (IP) para a transmissão direta, a seleção de relé único, bem como o esquema de seleção de múltiplos relés sobre o canal de desvanecimento Nakagami-m quando o bisbilhoteiro está dentro e sem a área de cobertura da fonte. Além disso, a compensação segurança-fiabilidade (SRT) destes três esquemas também é analisada. Verifica-se que o SRT da seleção multi-relé supera consistentemente a seleção de relé único, que tanto do esquema de seleção de relé único quanto do esquema de seleção multi-relé supera a transmissão direta quando o número de relés é grande, não importando o bisbilhoteiro. dentro ou fora da cobertura da fonte. Além disso, à medida que o número de relés DF aumenta, o SRT dos esquemas de seleção de relés melhora notavelmente. No entanto, o SRT de ambas as abordagens de seleção de relé piora quando o bisbilhoteiro está dentro da área de cobertura da fonte.

Abstract: In this paper, we investigate a cooperative communication system comprised of a source, a destination, and multiple decode-and-forward (DF) relays in the presence of a potential malicious eavesdropper is within or without the coverage area of the source. Based on the more general Nakagami-m fading channels, we analyze the security performance of the single-relay selection and multi-relay selection schemes for protecting the source against eavesdropping. In the single-relay selection scheme, only the best relay is chosen to assist in the source transmission. Differing from the single-relay selection, multi-relay selection scheme allows multiple relays to forward the source to the destination. We also consider the classic direct transmission as a benchmark scheme to compare with the two relay selection schemes. We derive the exact closed-form expressions of outage probability (OP) and intercept probability (IP) for the direct transmission, the single-relay selection as well as the multi-relay selection scheme over Nakagami-m fading channel when the eavesdropper is within and without the coverage area of the source. Moreover, the security-reliability tradeoff (SRT) of these three schemes are also analyzed. It is verified that the SRT of the multi-relay selection consistently outperforms the single-relay selection, which of both the single-relay and multi-relay selection schemes outperform the direct transmission when the number of relays is large, no matter the eavesdropper is within or without the coverage of the source. In addition, as the number of DF relays increases, the SRT of relay selection schemes improve notably. However, the SRT of both two relay selection approaches become worse when the eavesdropper is within the coverage area of the source.
