Nous proposons un MAC isochrone (I-MAC) utilisant le code temporel standard à ondes longues (appelé « horloge à ondes ») et introduisons une conception multicouche pour un nœud de capteur sans fil de faible consommation avec I-MAC. I-MAC a une heure de réveil périodique synchronisée avec l'heure réelle, et nous prenons donc l'horloge d'onde. Cependant, la fréquence d'un oscillateur à cristal varie en fonction de la température, ce qui entraîne une différence de temps entre les nœuds. Nous présentons un algorithme de correction temporelle pour résoudre ce problème et réduire le décalage horaire. Ainsi, la longueur du préambule dans I-MAC peut être réduite au minimum, ce qui permet d'économiser de la puissance de communication. Pour une réduction supplémentaire de la puissance, un oscillateur à cristal de faible puissance est également proposé, en tant que conception de couche physique. Nous avons implémenté I-MAC sur un nœud de capteur disponible dans le commerce pour estimer l'économie d'énergie et vérifié que la conception multicouche proposée réduit 81 % de la puissance totale, par rapport à l'écoute à faible consommation.

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.
