Neste artigo, propomos um projeto de cooperação em nível de pacote em camadas cruzadas para LANs sem fio que suportam adaptação de taxa. Mantendo a compatibilidade com LANs sem fio legadas, o controle distribuído da transmissão de pacotes multi-hop é habilitado sem pré-negociação de roteamento ou emparelhamento. Esses recursos são fornecidos pelo esquema de priorização baseado no IEEE 802.11e EDCF no qual definimos os parâmetros de acordo com a condição medida do link em cada terminal. A retransmissão de pacotes com alta taxa de transmissão faz um uso muito eficiente dos recursos de rádio e leva não apenas a melhorar o desempenho do sistema total, mas também a superar o problema de justiça conhecido na adaptação de taxa, onde os terminais com boas condições de enlace não conseguem obter recursos suficientes. devido ao tempo consumido pela transmissão de baixa taxa de dados. Essas vantagens são confirmadas através de simulações computacionais considerando a taxa de erro de pacote em cada transmissão que é assumida pela potência recebida calculada a partir da distância entre os terminais de origem, retransmissão e destino. Além disso, também discutimos sobre a justiça entre terminais habilitados para cooperação e legados quando coexistem no mesmo sistema, a fim de viabilizar a implantação gradual.

Abstract: In this paper, we propose a cross-layer design of packet level cooperation for wireless LANs that support rate adaptation. While keeping compatibility with legacy wireless LANs, distributed control of multi-hop packet transmission is enabled without pre-negotiation of routing or pairing. These features are provided by prioritization scheme based on IEEE 802.11e EDCF in which we set the parameters according to the measured link condition at each terminal. Relaying packets with high transmission rate makes much efficient use of radio resource, and it leads not only to improve performance of the total system, but also to overcome the fairness issue known in rate adaptation, where the terminals with good link conditions cannot gain enough resource because of the time consumed by low data rate transmission. These advantages are confirmed through computer simulations considering packet error rate at each transmission which is assumed by receiving power calculated from the distance between source, relay, and destination terminals. Furthermore, we also discuss about the fairness between cooperation-enabled and legacy terminals when they coexist in the same system, in order to make gradual deployment feasible.
