In this paper, a low cost but effective localization algorithm for Wireless Sensor Networks (WSNs) is introduced. From the proposed scheme unknown nodes only have to listen to three anchor nodes and establish a Space Standard Normal Vector (SSNV) to estimate the coordinates of them. Many localization algorithms for WSNs require the exits of extra components, such as a GPS, ultrasonic transceiver, and unidirectional antenna on sensor nodes. Conversely the proposed localization scheme is range-free which means there is no demanding of any extra devices for the sensors.
