Paper: An approach for safer navigation under severe hurricane damage.

A paper by Mohammad Eshghi and me on leveraging wireless sensor networks to allow municipalities to provide smartphone navigation services even when internet access, cell phone networks, and even electricity are no longer available. The simulated system allows users not only to reach their goal but most importantly to get there safely avoiding flooded areas and dangerous detours. We estimated a cost of only $12 per sensor node. Sensor nodes are to be installed in the streetlights in the area to be covered. Being installed in streetlights, there is no maintenance cost for battery exchanges.

Paper: “Is the Internet Spatial?”

Is the Internet Spatial? Given that electronic signals travel at the speed of light, spatial distance on the internet should play a negligible role. However, the economic success and importance of content distribution networks suggests otherwise.
A paper reporting on an experiment to answer this question is being published in the Journal of Reliable Intelligent Environments. The answer is “yes”, opening new perspectives towards solutions simplifying and unifying a range of protocols.

Research Opportunities

Cognitive systems at the reasoning-perception interface

Human reasoning uses analogies, metaphors, and analogous representations to greatly expand our horizons: we “grasp” a concept, or “see” how a complex phenomenon works. While many animals have amazing problem solving skills, human cognition is unique in its ability for higher reasoning, yet there is an explanatory gap between logic/mathematics and the associative structures we know underly human and animal cognition. Thanks to recent discoveries, we have a better understanding of this interface, which opens new pathways for both foundational and applied projects.
