Service Oriented architectures are becoming very popular to meet the requirements of complex current applications demanding distribution and heterogeneity in open environments. In this sense, the iLAND-ARTEMIS project is aimed at the development of a service-based middleware framework capable of supporting deterministic dynamic functional composition and reconfiguration of networked embedded service oriented applications. The approach proposed in this paper uses Model Driven Engineering (MDE) in order to guide the development of the iLAND applications from the specification to the execution through code generation, focusing on reconfiguration behavior at run-time, and assuring that non-functional requirements are met by an adequate resource assignment.
