RFID-based localization in heterogeneous mesh networks

Abstract

This paper will describe current and ongoing developments of wire less-connected RFID reader systems for evaluation of a passive user localization system. A two-tier architecture of different wireless-connected RFID readers will be introduced. On the lower level, i.e. the first tier, several wireless technologies can co-exist using different kinds of communication technologies to connect different RFID readers. These technologies are connected through a fully meshed WiFi/WLAN network to bring them into the IP world. This IP infrastructure is the second tier, built up on IEEE 802.11

“…al. [18] discusses a framework that combines RFID infrastructure with a wire less communication interface. This allows for the expansion of existing infrastructure, increasing environment coverage at a significantly lower cost than other options.…”

Spatial Inference Using Networks of RFID Receiver: A Bayesian Approach

“…Since active RFID receivers act similarly to WiFi antennas, their modelbased approach should also be applicable to active RFID localization. Thiem et al [10] proposed a localization of RFID tags in heterogeneous mesh networks.…”

“…In this paper, we address the challenge of inferring spatial information of detected RFID tags by aggregation of data streams from a network of RFID receivers. In contrast to the existing localization methods [6], [1], [10], [8], our spatial inference technique offers the following features:…”

“…Additionally, the GPS operations consume power quickly. As an alternative, a localization system may use various waves including electromagnetic waves of various frequency (e.g., common WiFi radio, Ultra-wideband [1], RFID radio [2], Infrared [3]), laser beam [4], and ultrasound [5]. The radiobased positioning is among the most popular techniques.…”
