Localization is one of the supporting technologies in wireless sensor networks. To identify the exact location of each and every sensor may not be feasible. In most of the sensor network application gathered by sensor will be meaningless without the location of sensor nodes. The researchers involve identifying localization of sensor node for the past years. The localization places a vital role in wireless sensor network. Exchange information with the environment through sensor and implement the function of collecting and delaying with data.
