Coordinates Determination of a Single Sensor Node with Respect to a Single Beacon Node using Received Signal Strength (RSS)

Abstract

In this humble project, we studied a certain localization problem in a terrestrial wireless sensor network (WSN). In this regard, we studied the issue of finding a single sensor node (i.e. mobile station, cell phone) under a single beacon node (i.e. BTS). Generally, the localization of a single sensor node in a terrestrial sensor network can be solved using multilateration technique with respect to three or more known beacon nodes. However, there is an area of concern, when the localization of a single sensor node (i.e. mobile station, cell phone) is to be measured with respect to only one known beacon node (i.e. BTS). We aim to solve such a challenge with the help of Received Signal Strength (RSS) Survey. In this project, we have simulated a terrain and created a model based on Received Signal Strength (RSS) Survey that defined the contours of RF coverage in a particular test facility under a single beacon node (BTS). Such a model could possibly give a solution for finding a single sensor node with respect to a single beacon node.
