The framework should address the issues of finding suitable devices automatically, composing feasible plans, and making the composed plans executable...
Cyber-Physical Systems (CPSs) are combinations of physical entities controlled by software systems to accomplish specified tasks under stringent real-time and physical entity constraints. As more and more physical entities are equipped with embedded computers, they are becoming more and more intelligent. However, the problem of effectively composing the services provided by cyber and physical entities...
Current service composition techniques and tools are mainly designed for use by service oriented architecture (SOA) professionals to solve business problems.
