摘要

6TiSCH工作组正在标准化工业物联网的低功耗无线协议栈。6TiSCH标准化的默认调度功能(SF0)使用简单的随机插槽选择。本文提出了低延迟调度函数(Low Latency Scheduling Function, LLSF)，这是一种新的调度函数，它采用菊花链而不是随机抽取时间段。我们在OpenWSN中实现了LLSF，并对其性能进行了实验评估。在没有额外成本的情况下，LLSF在5跳路径上的端到端延迟比SF0低82.8%。

LLSF: Low Latency Scheduling Function for 6TiSCH Networks

The 6TiSCH working group is standardizing the low-power wireless protocol stack for the Industrial IoT. The default scheduling function (SF0) standardized by 6TiSCH uses simple random slot selection. This paper proposes the Low Latency Scheduling Function (LLSF), a new scheduling function which daisy-chains timeslots rather than picking them randomly. We implement LLSF in OpenWSN and evaluate its performance experimentally. LLSF yields 82.8% lower end-to-end latency ona 5-hop path than SF0, at no extra costs.
