Dans le présent article, les performances des réseaux de relais coopératifs avec sélection de schémas de relais adaptatifs sont analysées. Le relais coopératif est une nouvelle technique permettant d'obtenir un gain de diversité spatiale en utilisant des stations voisines. Cependant, lorsque plusieurs stations émettent simultanément, le nombre de signaux d'interférence augmente. Par conséquent, l’introduction du relais coopératif dans les systèmes de communication radio n’augmente pas toujours la capacité du réseau en raison des interférences dans le même canal. Par conséquent, afin d’obtenir une efficacité spectrale élevée, il est nécessaire de sélectionner de manière adaptative un relais coopératif ou un relais non coopératif. En supposant des contrôles adaptatifs centralisés et décentralisés, l'efficacité du spectre est évaluée. La performance sous contrôle décentralisé est évaluée à l'aide d'une approche de la théorie des jeux. Les résultats de simulation montrent que l'introduction d'un relais coopératif avec contrôle centralisé augmente toujours l'efficacité spectrale. D'autre part, les résultats de la simulation montrent également que, lorsque chaque source sélectionne un schéma de relais indépendamment et égoïstement pour maximiser sa propre efficacité spectrale, l'introduction du relais coopératif peut réduire l'efficacité spectrale en raison de l'augmentation du nombre de signaux d'interférence.

Abstract: In the present paper, the performance of cooperative relaying networks with adaptive relaying scheme selection is analyzed. Cooperative relaying is a new technique to achieve spatial diversity gain by using neighboring stations. However, when multiple stations transmit simultaneously, the number of interference signals increases. Therefore, the introduction of cooperative relaying in radio communication systems does not always increase the network capacity due to the co-channel interference. Therefore, in order to achieve high spectral efficiency, it is necessary to select cooperative relaying or non-cooperative relaying adaptively. Assuming both centralized and decentralized adaptive controls, the spectrum efficiency is evaluated. The performance under decentralized control is evaluated using a game-theoretic approach. Simulation results show that the introduction of cooperative relaying with centralized control always increases the spectral efficiency. On the other hand, Simulation results also show that, when each source selects a relaying scheme independently and selfishly to maximize its own spectral efficiency, the introduction of the cooperative relaying may reduce the spectral efficiency due to the increase in the number of interference signals.
