Wireless Sensor Networks, an emerging technology, have been used in various fields for monitoring and tracking. Because of its application, the problem of localization is extremely important. Although a lot of algorithms have been presented recently, how to localization is a challenge. This paper describes how to classify localization algorithms and discusses the principles and characteristics of some localization approaches of range-free, such as DV-Hop, APIT, etc. The directions of how to improve DV-Hop algorithm is introduced as well.
