RSSI: Lost and Alone, a Case for Redundancy
The Received Signal Strength Indicator (RSSI) is a preferred metric among researchers for localization and distance estimation. Although it is easy to use, as it is available in most of operating systems, but it is not entirely reliable when used alone. We assess the inconsistency of RSSI values in an experimental setup.

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