Real-Time Service-oriented Communication Protocols on Resource Constrained Devices

Service-oriented architectures (SOA) become more and more important in connecting devices with each other. The main advantages of Service-oriented architectures are a higher abstraction level and interoperability of devices. In this area, Web services have become an important standard for communication between devices. However, this upcoming technology is only available on devices with sufficient resources. Therefore, embedded devices are often excluded from the deployment of Web services due to a lack of computing power and memory. Furthermore, embedded devices often require real-time capabilities for communication and process control. This paper presents a new table driven approach to handle rea time capable Web services communication, on embedded hardware through the Devices Profile for Web Services.
