Abstract

While wireless Internet access is getting increasingly more popular, the current internet architecture is not designd to address issues such as the unpredictable nature of the wireless medium and mobility. Furthermore, in the current architecture it is also difficult to make use of available opportunities like multiple options for a gateway or multiple network interfaces. To address these challenges, we propose M2: an architecture that relies on using visible Middleboxes to serve a pro-active Mobile-Host. M2 enables a number of techniques such as transport layer connection splitting, caching, pre-fetching, self-addressable ADUs, and cross layer information exchange. The combined use of a pro-active mobile-host and visible middleboxes specifically improves data transfer throughput in the presence of intermittent connectivity and variable network conditions. Our preliminary evaluation highlights the problems that exist in the current architecture and provides an estimate of the benefits that are achievable through M2.
