“…WSN/WSAN are core technologies for the Industrial Internet of Things (IIoT) [2], [3]. Significant examples of how they can be exploited in such context are the retrofitting of industrial plants for monitoring and diagnostics [4], greenhouse automation [5], heating, ventilation, and air conditioning (HVAC) systems [6], smart and precision agriculture [7], petrochemical industry [8] and many others. Several commercial solutions are based on the well-know IEEE 802.15.4 standard [9], including its Time Slotted Channel Hopping (TSCH) operating mode.…”

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.
