Propomos MAC isócrono (I-MAC) usando o código de tempo padrão de onda longa (chamado de "relógio de onda") e introduzimos o design de camada cruzada para um nó sensor sem fio de baixa potência com I-MAC. O I-MAC tem um horário de despertar periódico sincronizado com a hora real e, portanto, utilizamos o relógio de onda. No entanto, a frequência de um oscilador de cristal varia junto com a temperatura, o que incorre em uma diferença de tempo entre os nós. Apresentamos um algoritmo de correção de tempo para resolver esse problema e diminuir a diferença de tempo. Assim, o comprimento do preâmbulo no I-MAC pode ser minimizado, o que economiza energia de comunicação. Para maior redução de potência, também é proposto um oscilador de cristal de baixa potência, como um projeto de camada física. Implementamos I-MAC em um nó sensor pronto para uso para estimar a economia de energia e verificamos que o design de camada cruzada proposto reduz 81% da energia total, em comparação com Low Power Listening.

Abstract: We propose Isochronous-MAC (I-MAC) using the Long-Wave Standard Time Code (so called "wave clock"), and introduce cross-layer design for a low-power wireless sensor node with I-MAC. I-MAC has a periodic wakeup time synchronized with the actual time, and thus we take the wave clock. However, a frequency of a crystal oscillator varies along with temperature, which incurs a time difference among nodes. We present a time correction algorithm to address this problem, and shorten the time difference. Thereby, the preamble length in I-MAC can be minimized, which saves communication power. For further power reduction, a low-power crystal oscillator is also proposed, as a physical-layer design. We implemented I-MAC on an off-the-shelf sensor node to estimate the power saving, and verified that the proposed cross-layer design reduces 81% of the total power, compared to Low Power Listening.
