CA-BPEL: A New Approach to Facilitate the Development and Execution of Context-Aware Service Orchestrations

Acta Informatica Pragensia, 2022
The proliferation of smartphones and sensor-based networks has led to a greater need for context-aware applications and pervasive business processes. One of the key approaches that seek to satisfy this need is context-aware service composition.

Defining and Prototyping a Life-cycle for Dynamic Service Composition [PDF]

, 2008
Since the Internet has become a commodity in both wired and wireless environments, new applications and paradigms have emerged to explore this highly distributed and widespread system. One such paradigm is service-orientation, which enables the provision

Structured Service Composition [PDF]

, 2006
Composition languages like BPEL and many enactment tools only support structured process models, while most composition approaches only consider unstructured models. In this paper, we outline a semi-automatic approach for composing a set of services with data flow dependencies into a structured process model.
