On the design of a flexible software platform for in-building OTT service provisioning

Abstract

Abstract-We propose a software platform which pairs context awareness with over-the-top (OTT) service deployment. By augmenting OTT services with local context information, we allow them to react upon various types of changes in the environment in which they are being deployed. This lets service providers offer more personalized and fine-grained applications, while making use of a third-party infrastructure, via the OTT paradigm.Through UML diagrams, we describe the architecture of the proposed service platform. By means of a detailed illustrative scenario, the components involved are further clarified. In addition, in order to prove the feasibility of the architecture, a prototype implementation was developed and deployed on a large wireless sensor network test bed. Using a set of benchmarks, we identified the strengths and weaknesses of both test bed and prototype.

SeCoA: Autonomous semantic service composition algorithm in symbiotic networks

“…In previous work, we showed that the machines are capable of performing common ontological reasoning tasks. [16] WiLab's large number allowed us to run simulations in parallel.…”

Autonomous Service Composition in Symbiotic Networks

“…Thus, implicitly, at least two symbiotic networks are formed. In [2], we described a software architecture to enable such a context-aware over-the-top service platform, thereby presenting initial steps toward answering research question 5. It is displayed in Fig.…”

“…Initial benchmarks on WiLab have yielded favorable results, but further experimentation is needed. [2] We are still in the early stages of researching dynamic service composition. The body area network scenario will therefore be addressed further when we have sufficiently researched the case of mostly static in-building services.…”
