Simplifying fault diagnosis in locally managed rural WiFi networks

Abstract

The last three years have seen a lot of work in making WiFi-enabled Long Distance (WiLD) networking a reality in rural areas. Generally these networks are managed by non-local users who cannot guarantee long term support beyond a pilot. For long term operational sustainability, it is essential that maintenance duties be transferred to local administrators. In this paper, we argue that the research agenda should expand into areas of simplified diagnosis solutions as an en-abler for locally managed WiLD networks. Motivated by real faults we have seen in our own deployment at the Aravind Eye Hospital, we propose a framework to simplify diagnosis and show some initial results towards this direction. © 2007 ACM.
