Wireless sensor networks (WSN) have become possible because of the
on-going improvements in sensor technology. As the development of WSN, the application area using this technology is growing up. The Structure Health Monitoring (SHM) is the importance one way. Localization detection for sensor nodes is a new research point in the structure monitoring environment. Using signal strength is the common way for localization. However, the whole Wireless Sensor Networks is a power efficient system. One issue in smart sensor networks is achieving efficient operation because of the limited available power. So we must research the relationship between the sensor nodes' deployment and the system's power efficient.
