From: Physics-driven quantized consensus for distributed diffusion source estimation using sensor networks
Distributed multiple diffusion source estimation using SNs with noiseless links. The estimates achieved by each sensor at convergence of the unknown source parameters are shown for 10 independent trials of the experiment. The sensors are assumed to communicate over ideal links, so that the exchanged messages are unquantized. Furthermore, the spatiotemporal sensor measurements are assumed to be noisy, such that SNR =20 dB and K=10 for the family of spatial sensing functions. The scatterplot in a shows the true source locations (blue plus signs), the estimated locations (red cross) and one realization of the sensor distribution (green circles)
