We consider a group of autonomous communicating sensors, and our objective is to steer the group, with a low information exchange, towards the isotropic source of a diffusion process in steady-state. We suppose the graph describing the communication links between sensors to have a time-invariant ring-topology. Each sensor, which has no position information, takes pointwise measurements of the quantity...
We consider the problem of localizing the source of a diffusion process. The source is supposed to be isotropic, and several sensors, equipped on a vehicle moving without position information, provide pointwise measures of the quantity being emitted. The solution we propose is based on computing the gradient–and higher-order derivatives such as the Hessian–from Poisson integrals: in opposition to...
