Abstract

This paper presents the solution for a radio frequency localization system based on a wireless sensor network (WSN) using the IEEE 802.15.4 standard. The nodes are integrated in a smart antenna (SA) which four positions could be scanned with narrow beam-width as small as 21°. Our system utilizes a smart antenna that is able to cover wide space. Furthermore, this system uses fingerprinting methods that obtains an average localization error down to 0,75 m in the coverage area of 32 m2.
