Radio frequency identification (RFID), the process of identifying objects within a predefined protocol definition technologies serves its primary application for tracking objects. The three main approaches followed are estimating tag range information, RFID localization techniques and artificial intelligence approach. The objective of this paper is to summarize and compare the major methods used in different RFID stages. Various techniques for RFID as well as localizations protocols are reviewed here.
