Method and systems for locating a source of particle, molecule, or fragment of molecule using their reception rate
First Claim
1. A method for locating a source of particles, molecules, or fragments of molecules in a search space using a mobile sensor adapted to detect the presence of such particle, molecule, or fragment of particle, the method comprising:
- determining the particle, molecule, or fragment of molecule diffusion parameters in said search space;
designing a lattice on said search space;
determining if at least one particle, molecule, or fragment of molecule is detected by said sensor;
computing a probability for each node of said search space lattice to be the source of said particles, molecules, or fragments of molecules according to the determined particle, molecule, or fragment of molecule diffusion parameters and to the detected particles, molecules, or fragments of molecules;
evaluating a movement of said sensor according to said computed probabilities.

Abstract
A method and systems for locating a source of particles, molecules, or fragments of molecules using particle, molecule, or fragment of molecule reception rate is disclosed. According to the invention, the particle, molecule, or fragment of molecules diffusion parameters in the search space are determined and a lattice is designed on the search space. After having determined whether or not at least one particle, molecule, or fragment of molecule is detected by a sensor, a probability is computed for each node of said search space lattice. The probability associated to each node of the search space lattice corresponds to the probability that the particle, molecule, or fragment of molecule source is located on the node. Then, the move of the sensor is evaluated according to the entropy of the computed probabilities.
