Currently, the complexity of embedded software is increased, hence, more efficient design approaches are demanded. Although component based design is well-defined for developing Embedded Real Time (ERT) systems, the design and implementation of ERT component software is slow and complex. Distributed ERT systems can reduce the complexity of a component and increase its reliability and re-usability as well. Currently, Service Oriented Architecture (SOA) is an excellent technology for the implementation of distributed software. Some platforms are introduced to implement the components in SOA concept such as Service Component Architecture (SCA) and OSGI (Open Services Gateway Initiative). SCA provides a hierarchical component composition, distributed configurations and an interconnection with various means to design and combine services. However, SCA is unable to discover and reference services dynamically. In contrast, OSGI focuses on loading the service component. The services can be stopped, loaded and unloaded in frameworks supported by OSGI. Hence, this paper proposes an integration of SCA and OSGI to introduce a new framework for the implementation of distributed ERT systems.
