STPP: Spatial-Temporal Phase Profiling-Based Method for Relative RFID Tag Localization

Relative Localization of RFID Tags using Spatial-Temporal Phase Profiling

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 Radio Frequency Identification (RFID) tags have been proposed, they mostly focus on absolute object localization and are not suitable for relative object localization because of large error margins and the special hardwa...

Pseudorandom Tag Arrangement for Accurate RFID based Mobile Robot Localization

The optimal k-covering tag deployment for RFID-based localization

Radio Frequency Identification (RFID) technologies are applied in many fields for a variety of applications today. Recently, new solutions are proposed to deploy RF tags on the ground instead of attaching them to objects for RFID-based monitoring and localization. However, the optimal tag deployment strategy is yet to be addressed. In this paper, we identify the optimal deployment patterns that...

PATL: A RFID Tag Localization based on Phased Array Antenna

In RFID systems, how to detect the position precisely is an important and challenging research topic. In this paper, we propose a range-free 2D tag localization method based on phased array antenna, called PATL. This method takes advantage of the adjustable radiation angle of the phased array antenna to scan the surveillance region in turns. By using the statistics of the tags' number in differ...

An Inertial/RFID Based Localization Method for Autonomous Lawnmowers

Robotic lawnmowers currently available in the market cover their assigned area using a random reflection navigation strategy. While this strategy has been widely accepted for autonomous vacuum cleaning systems, it poses quality problems in outdoor applications since a randomic crossing of the garden can lead to an uneven mowing. In this paper we propose a localization algorithm based on a modif...
