Short Range Indoor Distance Estimation by Using RSSI Metric

Abstract

In recent years, indoor localizationproblem is a highly preferred topic to study. In order to estimate the relativepositions of the communication nodes in a localization system, the distanceinformation of each node is required. In this paper, it is aimed to estimatethe distances between the nodes by using the received signal strength (RSS)measurements. For an indoor environment, with the RSS based distance estimationmethods, the short range distances between the nodes can be estimated by usingthe Received Signal Strength Indicator (RSSI) measurements taken over astandard wireless communication infrastructure, namely Wi-Fi.
