  Abstract

Wireless Sensor Network monitors the environment in real-time by continuously collecting data from sensor nodes and sending it to the sync. Sensors have limited resources, so it is important to use energy efficiently. In addition, object tracking accuracy is also an important requirement when object tracking is performed in wireless sensor networks. To satisfy both at a high level, this paper proposes to dynamically switch sensing modes by predicting future movements of objects. Once the sensor nodes have synchronized sensing data to define the current state of object speed and direction. We use Q-learning to put it into a wake-up mode that temporarily leaves the optimal sensor region for each state on. Through simulations, we confirm that the proposed method increases energy efficiency with certain levels of accuracy satisfied.
