Hybrid Free-Space Optics/Radio Frequency (FSO/RF) Networks for Mobile Robot Teams

, 2008
In this paper, we introduce a hybrid free-space optics/radio frequency (FSO/RF) networking paradigm for mobile robot teams. We believe that such a model will emerge as a consequence of inherent limitations of RF based approaches.
