A Semantic Algorithm Repository and Workflow Designer Tool: Signal Processing Use Case

Recently major emphasis is exerted on development of effective tools and techniques for enriching IoT development environment. Typically an IoT application, for example a health monitoring application, not only requires domain knowledge of a programmer, but also similar knowledge from a medical practitioner, a sensor manufacturer, an infrastructure manager, etc. Such involvement of several experts makes the development process complex, resulting in escalation of time and cost of the effort. Model Driven Development (MDD) has been proposed as a development technique where such problem can be mitigated. This paper presents a system based on the MDD paradigm. As a part of the system, we present a work-flow designer framework, a visual drag and drop interface, where a developer can stitch various functional models recommended from a well-organized, annotated and crowd-sourced semantic repository of algorithms (from various domains), named as Algopedia, to quickly build a semantic workflow and in turn an end to end IoT application.
