Simulations and experiments for optimal deployment of an RFID‐based location‐aware system

Abstract

The proliferation of communication and mobile computing devices and local-area wireless networks has cultivated a growing interest in location-aware systems and services. An essential problem in location-aware computing is the determination of physical locations. RFID technologies are gaining much attention, as they are attractive solutions to indoor localization in many healthcare applications. In this paper, we propose a new indoor localization methodology that aims to deploying RFID technologies in achieving accurate location-aware undertakings with real-time computation. The proposed algorithm introduces means to improve the accuracy of the received RF signals. Optimal settings for the parameters in terms of reader and reference tag properties were investigated through simulations and experiments. The experimental results indicate that our indoor localization methodology is promising in applications that require fast installation, low cost and high accuracy.

Multi‐target localization in wireless sensor networks: a compressive sampling‐based approach

“…In most of the previous works , all sensor nodes are treated identically without considering the relationship between the variations of noise. In real applications, the accuracy of RSS measurements usually highly depends on the intensity of noise; for example, the signal‐to‐noise ratio (SNR) of RSS signals relies on the distance between the transmitter and the receiver . Note that in a densely deployed WSN, usually not all of sensors need to be activated at each time slot for real‐time monitoring or target localization.…”

On the Statistical Errors of RADAR Location Sensor Networks with Built-In Wi-Fi Gaussian Linear Fingerprints

“…Ranging from the military to public uses, from the urban to rural regions, and from the outdoor to indoor areas, location based services (LBSs) were already widely favored and popularized in the recent decade [4–6]. The typical LBSs mainly involve human navigation in unfamiliar buildings, robot path planning and guidance, health care inside modern hospitals, location-based enhanced sensing, entity and storage tracking and management.…”

“…The significantly growing interest in ubiquitous computing and context-awareness applications has required reliable, accurate and real-time localization technologies to locate the users’ positions in high-speed, seamless and heterogeneous wireless personal networks (WPNs), especially in the in-building environments where the Global Navigation Satellite System (GNSS) and geolocation in cellular system are not accurate enough [ 1 – 3 ]. Ranging from the military to public uses, from the urban to rural regions, and from the outdoor to indoor areas, location based services (LBSs) were already widely favored and popularized in the recent decade [ 4 – 6 ].
