Solutions for indoor tracking and localization have become more critical with recent advancement in context and location-aware technologies. [] Key Method The proposed SPKS fuses a dynamic model of human walking with a number of low-cost sensor observations to track 2-D position and velocity. Available sensors include Wi-Fi received signal strength indication (RSSI), binary infra-red (IR) motion sensors, and binary foot-switches. Wi-Fi signal strength is measured using a receiver tag developed by Ekahau, Inc…

RSSI based adaptive indoor location tracker
A generic application to track the location of any person in any area, with adequate Access Points (AP’s), by comparing the Received Signal Strength (RSS) at his/her position with the already stored set of RSS from the dataset using the Root Mean Square Error (RMSE) method.
Low-Power Centimeter-Level Localization for Indoor Mobile Robots Based on Ensemble Kalman Smoother Using Received Signal Strength
Preliminary experimental results imply that the proposed EnKS is able to achieve the best positioning accuracy, as high as 11.18 cm on average, but with a comparable computational complexity, which enables to meet the demands of many robot applications.
Ephemeral ID Beacon-Based Improved Indoor Positioning System
An indoor location tracking system that improves performance by correcting unstable RSSI signals received from BLE beacons is proposed and a filter algorithm based on the average filter and the Kalman filter is applied to reduce the error range of results calculated using the RSSI values.
SpringLoc: A Device-Free Localization Technique for Indoor Positioning and Tracking Using Adaptive RSSI Spring Relaxation
This paper introduces SpringLoc and a DFL algorithm that relies on simple parameter tuning and does not require offline measurements, showing significant improvement over the state-of-the-art, especially in situations with low-node deployment density.
Maximum convergence algorithm for WiFi based indoor positioning system
The approach for indoor positioning systems which is called the maximum convergence algorithm is proposed to find the accurate location by the strongest receiver signal in the small cluster and K nearest neighbours (KNN) of other clusters.
Kalman Filtering Framework-Based Real Time Target Tracking in Wireless Sensor Networks Using Generalized Regression Neural Networks
An implementation of GRNN is proposed as an alternative to this traditional RSSI-based approach, to obtain first location estimates of single target moving in 2-D in WSN, which are then further refined using Kalman filtering (KF) framework.

This paper proposes a robust sensor fusion algorithm to accurately track the spatial location and motion of a human under various dynamic activities, such as walking, running, and jumping. The
Radio Frequency Identification has proved its potential for locating objects in indoor environment and RFIDbased and RSS-based localization approaches estimates the RFID tag’s location by calculating the variation in the signal power as the distance varies of the tagreader.

Accuracy characterization for metropolitan-scale Wi-Fi localization

A novel technique for accurately estimating the locations of mobile devices and their wearers from wireless signal strengths by estimating time-varying device locations on a spatial connectivity graph whose outdoor edges correspond to streets and whose indoor edges represent hallways.
A wireless LAN-based indoor positioning technology
This paper presents a wireless-local-area-network-based (WLAN-based) indoor positioning technology that deploys a position-determination model to gather location information from collected WLAN signals and presents a tracking-assistant positioning algorithm to employ knowledge of the area topology to assist the procedure of position determination.
Sigma-Point Kalman Filters for Integrated Navigation
The improved state estimation performance of the SPKF is demonstrated by applying it to the problem of loosely coupled GPS/INS integration and an approximate 30% error reduction in both attitude and position estimates relative to the baseline EKF implementation is demonstrated.
Kernel-Based Positioning in Wireless Local Area Networks
It is shown that, due to the variability of RSS features over space, a spatially localized positioning method leads to improved positioning results and a kernelized distance calculation algorithm for comparing RSS observations to RSS training records is presented.

An algorithm for self-mapping is introduced that minimizes or even eliminates explicit calibration by allowing the location system to build this radio map as the system is used, and accuracy and coverage are shown to be comparable to those achieved with an explicit war-driven radio map.
