Planning-Based Method for Communication Protocol Negotiation in a Composition of Data Stream Processing Services

Data streaming is often used for video and sensor data delivery, nowadays gaining in popularity along with the development of mobile devices. In this paper we briefly describe a platform for automated composition of distributed data stream processing services. It decreases the complexity of composite service building process from the users point of view by introducing automation mainly in appropriate service selection and their communication protocols negotiation. This paper is focused on automated negotiation of communication protocols, which will be further used to transfer data among services. Data stream processing services are designed independently, often with many possible communication methods and not pointing directly to other services. With the use of the platform, they can be loosely coupled, forming a composite service od-demand. We present several approaches to communication protocol negotiation in a composition of data stream processing services and introduce planning-based approach. Finally, we discuss consequences of various approaches on an example composite service from image processing domain.
