EUCNC 2015, European Conference on Networks and Communications, June 29-July 2, 2015, Paris, France
The paper addresses the performance evaluation via the Cramer-Rao Lower Bound (CRLB) of power-based localization of a source in spatially-correlated log-normal propagation. The novel element is the inclusion and assessment of the impact of
conditioning measurements on such performance. The proposed model parameterizes performance by both the sensor topology (density, positioning) producing the current measurements as well as by conditioning measurements (essentially, prior or training
data) which reduce the statistical uncertainty in the model. Experimental results for indoor and outdoor environments are presented which quantify the expected localization accuracy, as well as identify practical issues to be further addressed. One main concern is the quantification of scaling on required sensornetwork size for achieving a pre-specified localization accuracy.
