Low-infrastructure methods to improve internet access for mobile users in emerging regions
As information technology supports more aspects of modern life, digital access has become an important tool for developing regions to lift themselves from poverty. Though broadband internet connectivity will not be universally available in the short-term, widely-employed mobile devices coupled with novel delay-tolerant networking do allow limited forms of connectivity. This paper explores the design space for internet access systems operating with constrained connectivity. Our starting point is C-LINK, a collaborative caching system that enhances the performance of interactive web access over DTN and cellular connectivity. We discuss our experiences and results from deploying C-LINK in Nicaragua, before moving on to a broader design study of other issues that further influence operation. We consider the impact of (i) storing web content collaboratively cached across all user nodes, (ii) hybrid transport layers exploiting the best attributes of limited cellular and DTN-style connectiv...
