Digital Ecosystem for Cross-domain Context Sensing and Trading

There is a need for exchange and trade of contextual information within ubiquitous computing environments between different providers of context-aware services. It is the need of a mobile user to obtain such services wherever he roams during the course of the day, such as home, workplace, leisure and visiting businesses, in a way that is safe and secure for both the user as well as the providers, while generating the maximum benefit from synergetically aggregating pieces of contextual information. A possible method to model the peer-to-peer relationships and complex structure of different interests is the introduction of digital ecosystems. The digital ecosystem is an emerging paradigm for economic and technological innovation. It consists of a self-organising digital infrastructure, aimed at creating a digital environment for networked organisations (or agents) thus supporting the cooperation, knowledge sharing and development of open and adaptive technologies and evolutionary, domain knowledge rich, environments.
