Abstract

The limited battery life of mobile handheld devices coupled with the lack of readily or reliable access to electricity is proving to be a major barrier to both adoption and usage of mobile Internet services in most African countries. Therefore, new methods of energy-efficient delivery of mobile web content are essential for prolonging battery life. This paper discusses and evaluates four energy-saving strategies, namely mobile optimization, HTTP compression, caching and proxy. The proposed energy-efficient proxy achieves at most 60% and 74% energy saving in 2G and 3G networks respectively without affecting user experience. As a case study, we consider usage trends and sample web content from three East African countries (Kenya, Tanzania and Uganda).
