SISI, acronym of Scalable Intermediary Software Infrastructure, is a flexible, dynamic and programmable intermediary infrastructure that enables ubiquitous access to the Web content. This framework has been designed with the goal of guaranteeing an efficient and scalable delivery of personalized services, namely edge services, at intermediate edge server on the WWW.

One of the our most important motivation is to let heterogeneous devices access to WWW information sources through a variety of emerging 3G wireless technologies, by allowing content adaptation and other complex functionalities such as geographical localization, group navigation and awareness for social navigation, translation services, adaptive compression and format transcoding, support for users with visual and motor disabilities.

SISI is able to dynamically compose edge services to match user preferences, device capabilities and network constraints.
