摘要: Several ways to estimate the position of a Wireless-Sensor-Network (WSN) node have been discussed in past years. Unlike outdoor solutions where Global Positioning System (GPS) could be used most applications, general solution for indoor usage has not found. The few existing localization on market are highly specialized and rely infrastructure or very expensive special designed hardware. Both — hardware do fit well into scenarios WSNs commonly because adhoc characteristics large amount nodes such installations. In this paper we present get precise estimation distance between two without needs purpose chips redesign already existent nodes. We use radio runtime measurement calculate algorithms refine measurements. A comparison with professional which is available also presented.
