Kami mencadangkan Isochronous-MAC (I-MAC) menggunakan Kod Masa Standard Gelombang Panjang (yang dipanggil "jam gelombang"), dan memperkenalkan reka bentuk rentas lapisan untuk nod sensor wayarles berkuasa rendah dengan I-MAC. I-MAC mempunyai masa bangun berkala yang disegerakkan dengan masa sebenar, dan dengan itu kami mengambil jam gelombang. Walau bagaimanapun, kekerapan pengayun kristal berbeza-beza bersama-sama dengan suhu, yang menimbulkan perbezaan masa antara nod. Kami membentangkan algoritma pembetulan masa untuk menangani masalah ini, dan memendekkan perbezaan masa. Oleh itu, panjang mukadimah dalam I-MAC boleh diminimumkan, yang menjimatkan kuasa komunikasi. Untuk pengurangan kuasa selanjutnya, pengayun kristal berkuasa rendah juga dicadangkan, sebagai reka bentuk lapisan fizikal. Kami melaksanakan I-MAC pada nod penderia di luar rak untuk menganggarkan penjimatan kuasa dan mengesahkan bahawa reka bentuk rentas lapisan yang dicadangkan mengurangkan 81% daripada jumlah kuasa, berbanding dengan Mendengar Kuasa Rendah.

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.
