Summary

This article describes an early warning system for mudslides and flood in rural El Salvador that uses a mesh network of simple devices. Reaccion worked with local villagers to develop a solution that fit their needs and cultural structures. The article can be used to highlight differences between the U.S., where a vast array of technological advances can aid in mitigating disasters, and remote areas of the world where many of the basic technologies involved, such as cell-phone networks, do not exist or are not reliable.

Extended Discussion Questions

  • In the article title, the author uses the term “IoT” (Internet of Things) to refer to the sensors and the mesh network of communication devices. What other areas of society does IoT impact, and how?
  • The article outlines how an automated solution (sensors) interacts with the knowledge of village elders, who have traditionally handled early warnings and analysis. How did the solution incorporate this aspect of the local culture? Can you think of other examples where culture impacts the design of computing solutions?
  • The article describes a mesh network of devices that connect peer-to-peer. What types of systems use peer-to-peer connections? How does the peer-to-peer structure impact the ways the system can be used?
