Abstract: Abstract-In order for nodes in a sensor network to meaningfully correlate their sensor readings, they must first determine their position in a globally shared coordinate system. Though there are many approaches which are suitable for achieving localization in the general case, sensor nodes are uniquely suited to use their sensing capabilities to aid them in this task. Global events which are detected in the environment surrounding the sensor network can serve as points of correspondence which, through collabor… Show more

“…In [2] the location of a sniper is determined in an urban terrain, by using the TDoA between an acoustic wave and a radio beacon. The PushPin project [8] uses the TDoA between ultrasound pulses and light flashes for node localization. The RADAR system [9] uses the RSSI to build a map of signal strengths as emitted by a set of beacon nodes.…”

“…In all these applications, location of events is necessary because without the physical location of events, information related to the events may not be useful. This makes localization a crucial issue in WSNs [2]. Global positioning system (GPS) [14] is the simplest way of estimating the location.…”
