A Framework for Dynamic Composition of Communication Services

Abstract

We propose a framework for dynamic composition of communication services that is well suited for facilitating research and prototyping on real experimental infrastructures of remotely configurable embedded devices. By using the concept of composability, our framework supports modular component development for various networking functions, thereby promoting code reuse. The framework consists of four components: the physical testbed, the module library, the declarative language, and the workbench. Its reference implementation, ProtoStack, developed using semantic web technologies, supports remote experimentation on sensor platform-based infrastructure and is thus well suited also for experimenters who do not possess their own physical experimentation infrastructure. We illustrate how ProtoStack supports research in service-oriented networks and cognitive networking. The cost of increased flexibility and prototyping speed of the protocol stack is paid in terms of increased memory footprint, processing speed, and energy consumption. Compared to the most related noncomposable approach, the CRime library used by ProtoStack has a 16-17% larger footprint, takes 2.4 times longer to execute an open-send-recv-close sequence, and consumes 1.6% more power in doing so. Even though with ProtoStack more resources are consumed by the node, the tradeoff in terms of prototyping speed pays off. ACM Reference Format:Carolina Fortuna and Mihael Mohorcic. 2014.

Dynamic composition components based on machine learning: architecture design and process

“…In [2] Chang et al present a design of a dynamic composition handler on enterprise service bus and analyzes different types of service compositions to clarity what dynamic composition really holds in service-oriented computing. At his turn Fortuna et al in [3] proposes a framework for dynamic composition of communication services that is well suited for facilitating research and prototyping on real experimental infrastructures of remotely configurable embedded devices. Elahraf et al in [4] present an integrated approach that facilitates the dynamic composition of an executable response process.…”
