The SPAN project is an open source implementation of a generalized Mobile Ad-Hoc Network framework. The project’s goals are to bring dynamic mesh networking to smart phones and to explore the concepts of Off-Grid communications.

I. INTRODUCTION TO SPAN Recent worldwide events have showcased that our current communications infrastructure is not as reliable as we would like to believe. Cellular towers can be destroyed by natural phenomena or simply overloaded beyond capacity and Wi-Fi hotspots are reliant on power and network connectivity, two things in short availability during a catastrophic event. We’ve seen these issues surface time and time, from Katrina to Haiti to Fukushima. It's always the same problem: no connectivity and no communication. The SPAN project [1] (Smart Phone Ad-Hoc Networks) attempts to ameliorate these issues by providing an alternate means for information dispersal. The project utilizes MANET (Mobile Ad-Hoc Network) technology to provide a resilient backup framework for communication between individuals when all other infrastructure is unavailable or unreliable. The MANET basd solution is a hadlss, infrastructur-lss network that allows common smart phones to link together in a dynamic way. As such, the SPAN project is harnessing the ubiquity of smart phones to provide durable communications in times of need.
