Abstract :
We consider a network of spatially distributed sensors deployed to track the intensity of a diffusing source whose location is fixed, but unknown. The sensors make discrete time concentration measurements and communicate them to a fusion center. We propose a recursive algorithm that can be used at the fusion center, which takes in the latest concentration measurements as input and produces an estimate for the source location and latest intensity as the output. The performance of the algorithm is verified through simulations.
