A Novel Method to Improve the Accuracy of the RSSI Techniques Based on RSSI-D

Journal of Networks, 2014
In this paper, a novel method is proposed to estimate the distance between sensor nodes based on a statistical model of GMM, which is established with the offline RSSI values, called RSSI-D. In order to estimate the arguments of RSSI-D with unobserved latent variables, EM is used to calculate the arguments of RSSI-D as accurately as possible in this ...

Reduction of RSSI variations for indoor position estimation in wireless sensor networks

Engineering and Applied Science Research, 2018
In this paper, the reduction of RSSI (received signal strength indicator) variation for indoor position estimation in wireless sensor networks (WSNs) is studied through simulation. We demonstrate that using raw RSSI data (with high variation) to estimate

BLE localization using RSSI measurements and iRingLA [PDF]

2015 IEEE International Conference on Industrial Technology (ICIT), 2015
Over the last few years, indoor localization has been a very dynamic research area that has drawn great attention. Many methods have been proposed for indoor positioning as well as navigation services. A big number of them were based on Radio frequency (RF) technology and Radio Signal Strength Indicator (RSSI) for their simplicity of use.
