digital sensors) wireless sensor networks (WSNs). The spatial physical phenomena are observed by a heterogeneous WSN, meaning that it partially consists of analog sensors and partially of digital sensors. The analog sensors transmit their (continuous) noisy observations to the Fusion Centre (FC), while the digital sensors first perform a simple thresholding and then transmit their binary values over imperfect wireless channels to the FC. The resulting observations are mixed continuous and discrete (1-bit decisions) values, and are combined in the FC to solve the inference problems. I will present novel algorithms to solve the aforementioned problems that are based on a multivariate series expansion approach resulting in a Saddle-point type approximation.
