Material flow management is an increasingly difficult activity in today's ever-more-complex manufacturing systems . New approaches are offered by the industrial internet of things (IoT), which is envisioned as a network of active devices that are capable of wireless communication . However, the dependence of IoT devices on battery energy presents a maintenance challenge. The paper proposes a self-organisation-based approach to improve the overall energy efficiency of workpiece localisation using IoT devices . A simulation study is performed to show the effects of transmitter effectiveness, material flow dynamics, and system scale on the energy efficiency.
