Abstract

In recent years there has been a growing interest in wireless sensor networks (WSN) applications. Such sensor networks can be used to control temperature, humidity, contamination, pollution etc. Self-organization and routing algorithms dedicated to wireless sensor networks usually assume that sensors absolute positions are unknown and all decisions are based on sensor's own local information. This assumption makes wireless sensor networks more flexible and energy conserve because making decisions locally is faster and energy efficient. But sooner or later sensors positions have to be found (when sensor sends a message about some event we of course would like to know where this event takes place). In this paper we describe different solutions of finding transceivers positions in wireless networks and we discuss localization in wireless sensor networks. We propose to transfer localization function from base stations to every sensor. We evaluate presented method using simulations.
