Neste artigo, o desempenho da Rede de Sensores Sem Fio (RSSF) usando nós de retransmissão fixos e tecnologia MIMO (Multiple-Input Multiple-Output) foi avaliado com base na capacidade de canal correlacionada do sistema MIMO e no número de nós sensores atendidos pelo sistema. . Além disso, a avaliação de desempenho do algoritmo proposto, que é usado para encontrar a distância ideal para colocar os nós de retransmissão do nó coletor, é feita não apenas com retransmissão AF e efeito de correlação espacial, mas também com Decode-and-Forward (DF) esquema de retransmissão. Os resultados mostram que o ganho do relé (uma razão entre o número máximo de sensores que satisfazem a capacidade de canal necessária na topologia de 7 células e o número de nós sensores na célula coletora) é fortemente afetado pela correlação espacial em alta capacidade de canal necessária, mas pouco com baixa capacidade de canal necessária. Os resultados também mostram que o ganho do relé pode ser melhorado notavelmente usando o esquema de retransmissão DF, e que a validade do algoritmo proposto é válida para qualquer esquema de retransmissão, efeito de correlação espacial e diferentes tamanhos de antena.

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.
