A taxa de transferência utilizável de um sistema IEEE 802.11 para uma aplicação é muito menor que a largura de banda bruta. Embora o 802.11b tenha um máximo teórico de 11 Mbps, mais da metade da largura de banda é consumida por sobrecarga, deixando no máximo 5 Mbps de largura de banda utilizável. Considerando esta característica, este artigo propõe e analisa um esquema de escalonamento distribuído em tempo real baseado nas redes ad-hoc sem fio IEEE 802.11 existentes, utilizando a plataforma de hardware Power Aware Sensing Tracking and Analysis (PASTA) da USC/ISI. Comparamos o esquema de escalonamento distribuído em tempo real com o esquema de pesquisa em tempo real para cumprir o prazo e comparamos uma largura de banda real medida com um resultado teórico. Os resultados teóricos e experimentais mostram que o esquema de escalonamento distribuído pode garantir tráfego em tempo real e melhorar o desempenho em até 74% em comparação com o esquema de polling.

Abstract: The usable throughput of an IEEE 802.11 system for an application is much less than the raw bandwidth. Although 802.11b has a theoretical maximum of 11 Mbps, more than half of the bandwidth is consumed by overhead leaving at most 5 Mbps of usable bandwidth. Considering this characteristic, this paper proposes and analyzes a real-time distributed scheduling scheme based on the existing IEEE 802.11 wireless ad-hoc networks, using USC/ISI's Power Aware Sensing Tracking and Analysis (PASTA) hardware platform. We compared the distributed real-time scheduling scheme with the real-time polling scheme to meet deadline, and compared a measured real bandwidth with a theoretical result. The theoretical and experimental results show that the distributed scheduling scheme can guarantee real-time traffic and enhances the performance up to 74% compared with polling scheme.
