Abstract

A calibration-free localization algorithm for sensor actuator networks is presented in this paper. The algorithm uses sequential importance sampling to estimate the location of a number of limited-capability sensors, using the strength of the signals transmitted from the sensor node to GPS-enabled mobile actuator nodes that work as anchor nodes. Simulation results show that the algorithm converges to an error range of 1 m in approximately 10 time steps, for very small Rice factors and four anchor nodes. The algorithm was verified using the network simulator NS-2.28
