In this paper, the Radio Frequency Identification (RFID) technology is used for indoor localization (i.e. location estimation). The location of a RFID reader is estimated based on the known locations of the RFID tags attached to the ceiling with 60 cm separation. Two arranged pattern of tags are considered. One is a square arranged pattern and another one is a triangle arranged pattern. Then, two...
In this paper, two novel localization algorithms using a fingerprint technique are proposed. The performance evaluation of these algorithms is compared by calculating the location estimation error. The feasibility for indoor and outdoor applications is investigated. The Radio Frequency Identification (RFID) System is utilized by the reader being the localized target. The passive tags are chosen as...
In this paper, the human body effect on indoor localization is evaluated based on experiments. Radio Frequency Identification (RFID) technology is used for this localization system. The location of a RFID reader is estimated based on the known locations of the RFID tags attached to the ceiling with 60 cm separation. Two cases of experiments are considered. For the first case, the RFID reader is attached...
In this paper, a novel approach for an indoor localization using a fingerprint technique is proposed. The UHF band Radio Frequency Identification (RFID) system is utilized. The passive RFID tags are employed as references attached to the ceiling at known locations and the RFID reader carrying on the vehicle of interest is the target to be localized. The basic principle of the fingerprint technique...
In this paper, radio frequency identification (RFID) technology is used for localization system. The location of a RFID reader is estimated based on the known locations of RFID tags using the UHF band RFID system. The new location estimation method based on the angulation technique is proposed to determine the reader location in real time. For angulation technique, the RFID reader is held on the camera...
In this paper, the improvement of an indoor localization using a fingerprint technique is proposed. The radio frequency identification (RFID) system is utilized. In general, the RFID localization can be categorized into two main types: one is the reader localization in which the reader locations will be estimated and one is the tag localization in which the tag locations will be estimation. The selection...
In this paper, the evaluation of two path model in ultra wideband (UWB) propagation channel with laptop computers for personal area network (PAN) is proposed. The UWB pulse with the specific center frequency and bandwidth is used for the transmitted signal. Complex form Friispsila transmission formula is applied for the UWB propagation channel, then the received signal is evaluated. The UWB path loss...
In this paper, a new radio source localization using array antennas based on fingerprinting techniques in an outdoor environment is presented. By using the fingerprinting technique, the finer the spatial resolution of the database, the more accurate the estimation of the location. Although this method is based on the subspace matching localization technique, a new approach in generating a fingerprint...
The fundamental performances of a radio source localization system were evaluated using the spatial information of the received signals by array antenna in outdoor experiments. We used the angle-of-arrival-based and newly proposed methods to estimate the location of a terminal. The proposed method of localization is based on the fingerprinting technique and uses the signal subspaces of the received...
