Original Abstract

Localization algorithms used in wireless sensor networks can be divided into two groups: range-free and range-based algorithms. Distance estimation is a basic procedure for the latter ones since they employ distances for position determination. Therefore, this paper deals with the investigation of signal propagation for the purposes of distance estimation. Distances can be determined from the received signal power; however, there are several phenomenons, which negatively influence the measurement of signal power. One of them, the uncertainty in a radio channel, is discussed in more details. The measurement of received signal power and the uncertainty in radio channel were performed. The measurement set-up and results from both indoor and outdoor are presented and discussed.
