摘要

IEEE802.15.4e TSCH是一個應用於MAC層的分時多工存取(TDMA)技術，能夠使感測節點高效傳輸及降低功率消耗。本文針對TSCH的MAC層提出一個完整的設計，包含了於mesh網路中的封包轉傳、節點間的時間同步、與基於auto ACK的傳輸模式等。每個感測節點都配置了一個三軸加速度計，取樣頻率可以達到200Hz。實驗結果證明了我們設計的軟體可以成功應用於架設mesh網路，並傳送大量的感測資料，同時也可以提高無線感測網路的使用時間。

IEEE802.15.4e Time Slot Channel Hopping (TSCH) is a technology of Time Division Multiple Access (TDMA) applied in Medium Access Control (MAC) Layers. In this paper, we present a completed designof the TSCH protocol including packet forwarding for mesh networking, time synchronization, and auto ACK based transmission. Each sensor node also equips a 3-axis accelerometer operating at sampling rate up to 200Hz. The experiment results show that the developed software can be used to successfully construct a mesh network to deliver a large amount of sensed data and also improve the lifetime of the wireless sensor network.
