Wireless sensor network acquires information from the surroundings using sensor, processes it, and then delivers it to other sensors or sink nodes through wireless interface. This kind of application of wireless sensor network can be used for various areas such as army, private sector, hospital and so on. To improve the efficiency of wireless sensor network, the study on the effective sensor placement methods is being conducted in many ways. Most of these studies do not mention that the environmental factors affect nodes when placing nodes. The reason is because there are too many environmental factors or sensors to be considered that affect other sensors, and because these factors are not easy to be recognized or classified. However, this study classifies and recognizes the factors that we need to consider when placing wireless sensor nodes. In addition, it finds how the sensor’s coverage affects those recognized items. By doing this, this study can be a foundation for the effective placement of sensor nodes in the future when wireless sensor network is built.
