This paper presents a new method for source localization of the gas diffusion using a wireless sensor network. The method has two steps: an initial estimation of the position of odor-source is obtained centrally by a robot and is based on particle filtering. It does not require any prior information about the position of the nodes. In the second stage, the nodes refine their position estimates employing a decentralized information filter. The paper includes several implementation aspects and experimental results.
