Wireless Sensor Networks (WSN) can be used in many application fields. The localization of sensor nodes, which is the foundation of the other applications, is to determine self-position using a certain localization scheme, according to the anchor nodes. In this paper, a thorough analysis for approximate point-in-triangulation test (APIT) algorithm is made, and an improvement of it is proposed. The analysis shows: compared with the original one, the improvement algorithm reduces the probabilities of In-To-Out Error and Out-To-In Error from the original one and the more perfectly theory has been appeared.
