Summary:
Wildlife has been damaging crops in mountainous areas where it is difficult to access commercial power sources. Therefore, a power-saving system for monitoring harmful wildlife has been proposed that combines multiple sensor nodes with different levels of power consumption. A sensor with higher power consumption capable of obtaining more detailed information is activated step by step after a sensor with low power consumption detects approaching harmful wildlife. However, such a method does not consider the coordination among multiple sensor nodes deployed in a region. An autonomous recording unit(ARU) uses sound to monitor wildlife intermittently for long-term operation to reduce power consumption. However, events are not captured when the ARU is in standby mode. Therefore, we propose a wildlife monitoring system that improves the probability of event acquisition while reducing power consumption by only activating sensor nodes in a target area. Other sensors are activated in standby mode by receiving wake-up calls sent by those sensor nodes when they detect events. We also evaluate the ability of event detection and power consumption of the proposed method.
