We study a new problem, refined localization, in this paper. Refined localization calculates
the location of an object in high precision, given that the object is in a relatively small region …

Passive Radio Frequency Identification (RFID) tags have been widely applied in many
applications, such as logistics, retailing, and warehousing. In many situations the relative …

In recent years, location-based services have been widely applied not only in daily life but
also in automation industries. As one of main location sensing technologies, RFID based …

Exploiting radio frequency signals is promising for locating and tracking objects. Prior works
focus on per-tag localization, in which each object is attached with one tag. In this paper, we …

Due to low cost and low complexity, passive ultrahigh-frequency radio-frequency
identification (UHF RFID) is gaining popularity in indoor localization. According to current …

Numerous ubiquitous computing applications depend on the ability to locate objects as a
key functionality. We show that Radio Frequency Identification (RFID) technology can be …

Object localization is a key primitive in pervasive computing environments, where numerous
applications depend on the rapid and accurate position estimation of objects. We present a …

There is much interest in fine-grained RFID localization systems. Existing systems for
accurate localization typically require infrastructure, either in the form of extensive reference …

RFID technology has been widely adopted in a variety of applications from logistics to
access control. Many applications gain benefits from knowing the exact position of an RFID …

Many object localization applications need the relative locations of a set of objects as
oppose to their absolute locations. Although many schemes for object localization using …
