IIoT的TSCH网络中的增强节能机制：PRIL方法
Enhanced Energy-Saving Mechanisms in TSCH Networks for the IIoT: the PRIL Approach
摘要：
无线传感器网络中微粒的寿命可以通过减少通信能量来延长。像时隙信道跳变这样的方法通过根据预定义的调度执行帧交换来实现这一目标，这有助于减少占空比。不幸的是，每当接收无线电接口是活动的但网络中没有人在发送时，就会发生空闲侦听。如果预先知道流量模式，如在周期性感测的相关情况下，则主动减少空闲侦听（PRIL）通过在接收器没有预期帧时禁用接收器来显著降低能量浪费。最佳PRIL操作要求在任何时候，链路的发送器和接收器侧都能对其状态（启用或禁用）有一致的看法。然而，这在存在确认帧丢失的情况下不能保证。本文提出并分析了应对此类事件的策略。通过离散事件模拟进行了广泛的实验活动，以确定从功能和性能的角度来看，上述错误可能产生的后果。结果表明，虽然没有一种策略在所有情况下都是最优的，但可以根据具体的操作条件采用不同的解决方案。
英文摘要：
Lifetime of motes in wireless sensor networks can be enlarged by decreasing the energy spent for communication. Approaches like time slotted channel hopping pursue this goal by performing frame exchanges according to a predefined schedule, which helps reducing the duty cycle. Unfortunately, whenever the receiving radio interface is active but nobody in the network is transmitting, idle listening occurs. If the traffic pattern is known in advance, as in the relevant case of periodic sensing, proactive reduction of idle listening (PRIL) noticeably lowers energy waste by disabling receivers when no frames are expected for them. Optimal PRIL operation demands that, at any time, the transmitter and receiver sides of a link have a coherent view of its state (either enabled or disabled). However, this is not ensured in the presence of acknowledgment frame losses. This paper presents and analyzes some strategies to cope with such events. An extensive experimental campaign has been carried out through discrete event simulation to determine what consequences above errors may have from both a functional and performance viewpoint. Results show that, although no strategy is optimal in all circumstances, different solutions can be profitably adopted depending on the specific operating conditions.
