英文摘要：

Indoor localization is a prerequisite for Location Based Services（LBS） ,it is research hotspot in recent years, and receive widespread attention from academia and industry. With the popularity of smart terminal, many kinds of indoor localization method which is based on WiFi and smart terminal are proposed. Compared with the previous localization method,indoor localization based on WiFi and smart terminal has advantages. Through the key factors of large scale application of indoor localization, this paper analyzes and summarizes the basic methods of indoor localization based on WiFi and smart terminal systematic. With the comparison of typical work in recent years, it points out the shortage of present work,and prospects on the difficulties and direction of the research on indoor localization based on WiFi and smart terminal.
