Dans cet article, les performances du réseau de capteurs sans fil (WSN) utilisant des nœuds de relais fixes et la technologie MIMO (Multiple-Input Multiple-Output) ont été évaluées sur la base de la capacité de canal corrélée du système MIMO et du nombre de nœuds de capteurs desservis par le système. . De plus, l'évaluation des performances de l'algorithme proposé, qui est utilisé pour trouver la distance optimale pour placer les nœuds relais du nœud récepteur, se fait non seulement avec le relais AF et l'effet de corrélation spatiale, mais également avec Decode-and-Forward (DF) schéma de relais. Les résultats montrent que le gain de relais (un rapport entre le nombre maximum de capteurs satisfaisant la capacité de canal requise dans une topologie à 7 cellules et le nombre de nœuds de capteurs dans la cellule puits) est fortement affecté par la corrélation spatiale à une capacité de canal requise élevée, mais peu. à une faible capacité de canal requise. Les résultats montrent également que le gain du relais peut être remarquablement amélioré en utilisant le schéma de relais DF, et que la validité de l'algorithme proposé est valable pour tout schéma de relais, effet de corrélation spatiale et différentes tailles d'antenne.

Abstract: In this paper, the performance of the Wireless Sensor Network (WSN) using fixed relay nodes and Multiple-Input Multiple-Output (MIMO) technology was evaluated based on the correlated channel capacity of MIMO system and the number of sensor node served by the system. Moreover, the performance evaluation of the proposed algorithm, which is used to find the optimum distance to place the relay nodes from sink node, is done not only with AF relaying and spatial correlation effect, but also with Decode-and-Forward (DF) relaying scheme. The results show that the relay gain (a ratio between the maximum number of sensors satisfying the required channel capacity in 7-cell topology to the number of sensor nodes in sink cell) is affected strongly by the spatial correlation at high required channel capacity but little at low required channel capacity. The results also show that the relay gain can be improved remarkably by using the DF relaying scheme, and that the validity of the proposed algorithm holds for any relaying scheme, spatial correlation effect and different antenna size.
