Protocolos MAC de ciclo de trabalho foram propostos para redes de sensores sem fio (RSSFs) para reduzir a energia consumida pela escuta ociosa, mas introduzem uma latência de entrega ponta a ponta significativa. Vários trabalhos tentaram mitigar essa latência, mas ainda apresentam problemas no tratamento da perda de pacotes. A qualidade do canal sem fio nas RSSFs é muito ruim, então os pacotes são frequentemente perdidos. Nesta carta, apresentamos um novo protocolo MAC de ciclo de trabalho, denominado REMAC (Retransmission-Enhanced duty-cycle MAC), que explora tanto a camada de rede quanto as informações da camada física. O REMAC estima a qualidade do canal sem fio e reserva adequadamente o canal sem fio para lidar com a perda de pacotes. Ele pode reduzir a latência de entrega de pacotes ponta a ponta causada pela perda de pacotes sem sacrificar a eficiência energética. Os resultados da simulação mostram que o REMAC supera o RMAC em termos de latência de entrega de pacotes ponta a ponta.

Abstract: Duty-cycle MAC protocols have been proposed for wireless sensor networks (WSNs) to reduce the energy consumed by idle listening, but they introduce significant end-to-end delivery latency. Several works have attempted to mitigate this latency, but they still have a problem on handling the packet loss. The quality of the wireless channel in WSNs is quite bad, so packets are frequently lost. In this letter, we present a novel duty-cycle MAC protocol, called REMAC (Retransmission-Enhanced duty-cycle MAC), which exploits both the network layer and the physical layer information. REMAC estimates the quality of the wireless channel and properly reserves the wireless channel to handle the packet loss. It can reduce the end-to-end packet delivery latency caused by the packet loss without sacrificing the energy efficiency. Simulation results show that REMAC outperforms RMAC in terms of the end-to-end packet delivery latency.
