The conventional sources of energy for sensing nodes in wireless sensors networks (WSN) that are utilized to monitor the health of structures are lithium-ion batteries. Improving the stability and durability of the energy supply for the sensing nodes in a WSN is an important goal in the field of SHM. The periodic entering of control sensors into a low-power mode or sleep state is frequently used to reduce their energy consumption. However, the need for faultless time synchronization makes implementation in large-scale WSNs difficult. If a node receives a sampling command but is in the listening-time cycle, then the sampling process is delayed. In that case, a radio triggering function can improve the stability and durability of a sensing node when it is integrated with an external low-power circuit that is attached to a sensing node. Wirelessly transmitting a wakeup command when particular start-up conditions are met to awaken wireless sampling nodes is effective. This work proposes a dual radio cooperation scheme that is based on the wake-on-radio (WOR) method to construct an intelligent, energy-saving WSN. Four testing cases are investigated and the power consumptions are measured and compared. The intelligent sensor is a more effective conventional sensor than traditional alwayson sensing nodes in measuring structural responses to an earthquake, as it has a longer sleeping time, saves energy and extends the lifetime of the associated wireless sensing system.
