Service identification guideline for developing distributed embedded real-time systems

Analysis and design are the key phases in any software development life cycle. Service identification is one of the most important steps performed in the analysis phase of service-oriented software development life cycle. Service-orientation has been applied successfully in the domain of distributed embedded real-time system because of the advantages it provides such as reusability and interoperability. However, a systematic service-oriented development methodology for distributed embedded real-time system is still missing. A step-by-step guideline for service identification is presented in this study as part of an attempt to define the analysis phase of service-oriented software development life cycle for distributed embedded real-time system. The Smart Home case study is applied to verify the guidelines. This study provides profound descriptions on how to identify services for distributed embedded real-time system. Moreover, this work can be used as a first step towards a systematic service-oriented software development life cycle for distributed embedded real-time systems.
