Symbiotic Service Composition in Distributed Sensor Networks

Tim De Pauw, Bruno Volckaert, Anna Hristoskova, Veerle Ongenae, Filip De Turck
2013 International Journal of Distributed Sensor Networks  
To accommodate services in large-scale symbiotic networks, including wireless sensor networks, we propose a software platform which autonomously constructs and orchestrates such compositions.  ...  By allowing the software services provided in such networks to operate in an equally symbiotic manner, new opportunities for the so-called service compositions arise, which take advantage of the multitude  ...  If we apply these concepts to the patient care scenario that we introduced earlier, we obtain the OWL-S services shown in Thus, for each parameter exchange in the constructed service invocation graph,  ...

Automatic Web Service Composition – Models, Complexity and Applications [article]

Paul Diac
2020 arXiv   pre-print
The automatic composition of web services refers to how services can be used in a complex and aggregate manner, to serve a specific and known functionality.  ...  In this regard, we consider that web services and compositions requests can be added and removed in real-time, and the system must handle such operations on the fly.  ...  a mobile health-care scenario.  ...

Automated Service Composition Using AI Planning and Beyond [chapter]

Michel Medema, Eirini Kaldeli, Alexander Lazovik
2021 Lecture Notes in Computer Science  
Automated Service Composition is one of the "grand challenges" in the area of Service-Oriented Computing.  ...  In this chapter, we look at the development of the original vision of automated service composition as AI planning, going from planning with extended (rich) goals, further developing into composition under  ...  The rest of the chapter is organised as follows. Section 2 discusses the use of planning for automated service composition.  ...

Systematic Scalability Modeling of QoS-Aware Dynamic Service Composition

Leticia Duboc, Rami Bahsoon, Faisal Alrebeish, Carlos Mera-Gómez, Vivek Nallur, Rick Kazman, Philip Bianco, Muhammad Ali Babar, Rajkumar Buyya
2022 ACM Transactions on Autonomous and Adaptive Systems  
In Dynamic Service Composition(DSC), an application can be dynamically composed using web services to achieve its functional and Quality of Services (QoS) goals.  ...  The paper then applies the technique to two different approaches for QoS-aware dynamic services composition, where the paper describes two detailed exemplars that exemplify its application.  ...  Given such a scenario, it is not surprising that scalability is an important concern in the domain of QoS-aware dynamic service composition.  ...

Towards Composition Management for Component-based Peer-to-Peer Architectures

Sascha Alda, Armin B. Cremers
2005 Electronical Notes in Theoretical Computer Science  
Recent peer-to-peer architectures do not fulfill the idea of a service-oriented architecture to allow the flexible composition of services towards concrete applications.  ...  In this work, the peer-to-peer architecture DeEvolve is presented that provides novel ways for the composition of services including the handling of exceptions such as the failure of peers.  ...  For the composition of a word processor as exemplified in Section 3.3, the following minimal composition as provided in Fig. 5 could be reasonable.  ...

Compositional schedulability analysis of real-time actor-based systems

Mohammad Mahdi Jaghoori, Frank de Boer, Delphine Longuet, Tom Chothia, Marjan Sirjani
2016 Acta Informatica  
To check schedulability, we introduce a compositional automata-theoretic approach, based on maximal use of model checking combined with testing.  ...  Schedulability analysis in this setting amounts to checking whether, given a scheduling policy for each actor, every task is processed within its designated deadline.  ...  In Sect. 3, we explain how we model real-time actors and exemplify this by means of a peer-to-peer case study. A review of our compositional schedulability analysis technique is given in Sect. 4.  ...
