Every WiFi, ZigBee or Bluetooth compatible radio chip provides a byte of information related to the received signal strength (RSS), the so called received signal strength index (RSSI). In a given point in space, on a specific radio channel, the RSS has a unique value at a given moment in time. Still, radio chips produced by different manufacturers will report different RSSI numbers. So RSSI is ...

In this paper, the integration of directional antennas in a room-level received signal strength (RSS) fingerprinting-based indoor localization system (ILS) is studied. The sensor reader (SR), which is in charge of capturing the RSS to infer the tag position, can be attached to an omnidirectional or directional antenna. Unlike commonly-employed omnidirectional antennas, directional antennas can ...

With the proliferation of location based services (LBS), various indoor localization systems have been proposed based on received signal strength (RSS). An acceptable localization performance is achieved by using fingerprinting-based methods. However, its performance is restricted by RSS deviation. This deviation is not well modelled and studied in past. With this motivation, we propose a novel...

Nowadays, a variety of information related to the distance between two wireless devices can be easily obtained. This paper presents a hybrid localization scheme that combines received signal strength (RSS) and round-trip time (RTT) information with the aim of improving the previous localization schemes. The hybrid localization scheme is based on an RSS ranging technique that uses RTT ranging es...

Double robust extreme ranked set sampling (DRERSS) and its properties for estimating the population median are suggested. The performance of DRERSS with respect to simple random sampling (SRS), ranked set sampling (RSS) and extreme ranked set sampling (ERSS) schemes is considered. Real data set that consist of heights of 346 students are used to evaluate the DRERSS method. It is found that when...

It is recommended that performance validity be assessed in all neuropsychological cases involving external incentive. The present study sought to develop an embedded performance validity measure based on the Spatial Span task of the Wechsler Memory Scale-III in a sample of litigating persistent postconcussion complainants. The Reliable Spatial Span (RSS) calculation had specificity, sensitivity...

WLAN (WiFi) RSS database for fingerprinting positioning This data set contains two WLAN Received Signal Strengths (RSS) databases suitable for fingerprinting positioning. One database contains training data (Training_rss.csv, Training_coordinates.csv), the radio map, the second database contains test data (Test_rss.csv, Test_coordinates.csv), RSS measurements on a path and the coordinates of th...

Executive Summary Students in higher education today are technologically savvy and expect faculty to use myriad web technologies for course delivery. This includes taking advantage of email, course web sites, and online learning communities. However, expectations now also include RSS, blogs, web-, pod-, and vod-casting, extending the classroom experience to provide active learning materials any...
