摘要

随着物联网的出现，能源消耗变得重要起来。ETSCH在TSCH中引入了高质量信道白名单和增强信标的信道列表，以提高动态干扰下的可靠性。然而，由于能量检测节点的能量消耗大于其他节点，ETSCH很难扩展到多跳网络。在本文中，我们提出了自适应信道质量估计(A-CQE)，它根据提出的干扰动态来控制能量检测的频率，以确定干扰是否是动态的。实验表明，与ETSCH相比，采用A-CQE的ETSCH在不降低可靠性的前提下，在能耗方面平均提高了10.1%。

Adaptive channel quality estimation method for enhanced time slotted channel hopping on wireless sensor networks

As IoT emerges, energy consumption becomes important. ETSCH introduces whitelisting high-quality channels in TSCH and channel list for Enhanced Beacons, to improve reliability under dynamic interference. However, it is difficult to extend ETSCH to multi-hop network because energy consumption of energy-detecting nodes is larger than that of other nodes. In this paper, we propose Adaptive Channel Quality Estimation (A-CQE), which controls frequency of energy detections depending on Interference Dynamicity that are proposed to determine whether interference is dynamic or not. Experiments show ETSCH with A-CQE improves on average 10.1% in terms of energy consumption without lowering reliability compared with ETSCH.
