The main objective of this paper is to provide people who use smartphones with a convenient way of getting useful information by making their smartphones communicate with the XCREAM (XLogic Collaborative RFID/USN-Enabled Adaptive Middleware). We have developed the XCREAM, which is a smart mediator between many types of sensor devices and applications. It gathers a variety of raw data from many ...

The performance of a wireless communications system is largely guided by the Bit Error Rate that the system experiences on a given wireless channel. The issue of wireless channel equalization and tracking has attracted increased attention in recent years. These techniques are able to provide significant enhancements in performance in some of the most severe channel conditions with time-varying ...

RFID technology has proven to be an effective solution in many applications for monitoring demented patients. However, its wider acceptance is still limited by prohibitive deployment costs, technological limitations and privacy concerns. In this paper, an RFID-based indoor tracking system was analyzed regarding an additional barrier of RFID’s acceptance which is an issue of choosing an appropri...

In this paper we introduce and describe a radio frequency-based system for location identification and tracking. The basic design of the system consists of transmitters in the environment, transceivers on the person or object for which location information is desired, and a receiver in the environment. Each of these three pieces of hardware and their associated software are discussed in this pa...

Inventory shrinkage is a common problem in the management of returnable containers. RFID-based container tracking systems have been proposed as a possible solution. Benefits of RFID-based tracking of returnable transport items such as pallets, kegs and boxes are documented in several case studies, but have so far hardly been analyzed from a theoretical perspective. In this article, we analyze t...

Air-to-sea surveillance and tracking systems that provide rapid and positive identification of Non-Cooperative and Stealthy Targets (NCSTs) are connected with Inverse Synthetic Aperture Radar (ISAR) concepts and techniques. ISAR has several shortcomings that could be dealt with the contribution of a Phase Comparison Monopulse system. This paper presents the possible output for the height dimens...

In this paper we present a continuous 24 hour data collection and a semi automated data analysis of laboratory mice in a spacious indoor environment. The data is collected via an RFID tracking solution, a scale and an optical tracking system. The visualisation and the premilary analysis of the data provide information about behavioural and movement patterns of laboratory mice under semi-natural...

Autonomous aerial robots provide new possibilities to study the habitats and behaviors of endangered species through the efficient gathering of location information at temporal and spatial granularities not possible with traditional manual survey methods. We present a novel autonomous aerial vehicle system to track and localize multiple radio-tagged animals. The simplicity of measuring the rece...

All research to date using wireless networks for wildlife tracking has concentrated on monitoring a single species, using large GPS enabled collars. These collars are too heavy to attach on smaller animals. Rather than omit small animals from the tracking spectrum, we show how a fusion of GPS tracking (where applicable) and an improved version of VHF tracking can result in a system which is abl...
