Treffer: Programming Context-Aware Pervasive Computing Applications with TOTA

Pervasive computing calls for suitable programming models and associated supporting infrastructures to deal with large software systems dived in complex and dynamic network environments. Here we present TOTA, a new approach for the development of pervasive computing applications. TOTA proposes relying on tuple-based information to be spatially diffused in the network on the basis of some application-specific propagation rule, to be exploited by application agents to achieve context-awareness and to effectively coordinate with each other. As shown with the help of a case study scenario, TOTA, while promoting a simple programming model, is effective to facilitate access to distributed information, navigate in complex networks, and enforce complex coordination activities in an adaptive way.
