Abstract
In this paper, we investigate the sensor localization problem and present Stochastic Radio Interferometric Positioning System with Unsynchronized Modulated Signals (SRIPS_UMS). Previous radio interferometric positioning methods have limitations include (1) strict hardware requirements for Received Signal Strength Indicator (RSSI) circuitry (2) time synchronization problem between distributed hardware. SRIPS_UMS overcomes these by using unsynchronized interferometric modulated signals. Its viability and advantages are demonstrated through mathematical models and extensive simulations. Further, the ongoing hardware implementation based on CC2420 is presented.
