摘要：A problem with RSSI localization methods has been dependence on assumptions about the source signalstrength or dependence on knowledge of its value at the source. This paper presents a solution to WSNlocalization for planar WSNs which averts this problem. It is a small, fine grained, range-based, beaconless,GPS-free, low cost RSSI technique which requires an irregular arrangement of four omnidirectionalantennas for accurate positioning of the source and also for the determination of the source signal strengthat the source. A spiral arrangement of antennas is described and software simulation of the localizationprocess is presented that demonstrates its accuracy. Five omnidirectional antennas are fully sufficient toenable the avoidance of blind spots.
