Demo: MadApp: Dynamic content support for delay-tolerant web applications

This paper showcases MadApp, an application-level development framework that supports the expressive development and flexible deployment of applications for web applications in delay-tolerant networks. MadApp allows web applications to be developed in two pieces. First, a static piece that contains unchanging content can be downloaded from a traditional web server. This static piece may specify “holes” that designate places in which dynamically collected content can be integrated into the web application as this content is opportunistically collected from the pervasive computing environment. MadApp supports both the development of these web applications by making is easy to specify this missing content and how it is dynamically integrated and the deployment of the web applications by providing middleware support for collecting and integrating content on the fly. This demonstration showcases how MadApp can be used to support such opportunistic web applications through a webpage integrated with the demonstration event itself. Users will be able to download a web page that contains a static map and a listing of the demonstrations. As users move through the demonstration space, they can generate content, e.g., photos of demonstrations, which their app will then share opportunistically with others in the exhibition space.
