Distance & Location Estimation and the Potential Use for Smart Phone Applications in Wireless Sensor Network

Abstract

This thesis focuses on how well the CC2430 devices provided by Texas Instruments can be used with its RSS measurements to perform distance and location estimation in Wireless Sensor Network. Measurements were carried out to determine the limitations of TI devices as well as the factors which will influence the performance of the RSS measurements in indoor environments. Distance and location estimation theories have been introduced along with the implementation of these theories into practical applications. This thesis contains the details of equipment used in the measurement, the measurement planning, procedure and technique. Measurement results are presented and the observed characteristics of measurement by TI devices are discussed. In the end, the main purpose of this study is to achieve a robust and cost effective method for distance and location estimation. Results in this thesis showed that the previous statement could be achievable.
