Preliminary definition of CORTEX programming model

The objective of D2 is to design a preliminary programming model suitable for the development of proactive applications constructed from mobile sentient objects. D2 embodies an early deliverable that will be followed in the second half of the project by its successor deliverable D6, the final definition of the CORTEX programming model. It outlines our definition of sentient objects and describes how an application developer may program them in a context aware manner. Furthermore, D2 describes the event-based communication model made available to the application programmer to define inter-object communication. And finally, D2 presents a first approach to specifying QoS parameters characterizing the level of service supported by the underlying infrastructur
