Real Time Application

Elasticsearch has become an attractive open-source search and analytics engine for use cases such as log analytics, click stream analytics and real-time application monitoring. As a service, Elasticsearch is made available by Amazon Web services, Searchly.com, Bonsai and many other websites as a hosted engine. This hosted Elasticsearch service is known as Elastic Cloud. The aim of AWS (Amazon Web Services) is to provide Elasticsearch as a service to users. These web services can implement Service-oriented Architecture. In the following chapter Potential Reach is aggregated using the server. Potential Reach is a metric that indicates the reach of an online activity like tweet or comment. This number helps media marketers track the success of the brand or company.

And Performance

Real time impact in many applications is the subject of a recent field of studies in information systems. Web services are a solution for the integration of distributed information systems that are autonomous, heterogeneous and auto adaptable to the context. This impact can resolve many problems in different systems based on Service Oriented Architecture (SOA) and web services. In this paper, the authors are interested in defining an approach to provide the different needs of self-adaptability of SOA to the context based on workflow, define the real time goal in their approach and show the feasibility and performance evaluation of their approach in an ambulance trajectory case study.

Concise Description

One of the key challenges of the Service Oriented Architecture is the discovery of relevant services for a given task. In Semantic Web Services, service discovery is generally achieved by using the service profile ontology of OWL-S. Profile of a service is a derived, concise description and not a functional part of the semantic web service. There is no schema present in the service profile to describe the input, output (IO), and the IOs in the service profile are not always annotated with ontology concepts, whereas the process model has such a schema to describe the IOs which are always annotated with ontology concepts. In this paper, we propose a complementary sophisticated matchmaking approach which uses the concrete process model ontology of OWL-S instead of the concise service profile ontology. Empirical analysis shows that high precision and recall can be achieved by using the process model-based service discovery.

Σκοπός της παρούσας διδακτορικής διατριβής ήταν η σχεδίαση-υλοποίηση, προσομοίωση και μοντελοποίηση ασύρματων δικτύων αισθητήρων (ΑΔΑ) που βασίζονται στην αρχιτεκτονική IPv6 over low power wireless personal area networks (6LoWPAN) και υποστηρίζουν υπηρεσίες ιστού (web services) όπως επίσης και η υλοποίηση καινούριων τέτοιων υπηρεσιών καταλληλότερων για εφαρμογή στα προαναφερθέντα ΑΔΑ. Λόγω της έλλειψης που παρατηρείται στην παροχή εργαλείων για την εκπλήρωση του παραπάνω στόχου, αναπτύχθηκε ένα πειραματικό ΑΔΑ και ένα εργαλείο προσομοιωτικών μετρήσεων της επίδρασης των υπηρεσιών ιστού σε 6LoWPAN ΑΔΑ καθώς επίσης και ένα μαθηματικό μοντέλο για την μελέτη του πρωτοκόλλου ελέγχου προσπέλασης στο μέσο μετάδοσης (MAC) αυτών των δικτύων. Το προτεινόμενο MAC πρωτόκολλο για την 6LoWPAN αρχιτεκτονική είναι o χωρίς σχισμή (unslotted) CSMA/CA μηχανισμός του ΙΕΕΕ 802.15.4 προτύπου. Στα πλαίσια της παρούσας διδακτορικής διατριβής υλοποιήθηκε μια καινούρια στοίβα πρωτοκόλλων για υπηρεσίες ιστού η οποία ονομάστηκε Tiny service oriented architecture for wireless sensors (SOAWS). Το Tiny SOAWS προσφέρει μειωμένη κατανάλωση μνήμης, μειωμένο χρόνο εκτέλεσης καθώς επίσης και μειωμένα μεγέθη ανταλλασσόμενων μηνυμάτων σε σχέση με το πρότυπο device profile for web services (DPWS) το οποίο δημιουργήθηκε για την απευθείας ενσωμάτωση των υπηρεσιών ιστού σε συσκευές. Επίσης, το Tiny SOAWS υποστηρίζει την δημιουργία υπηρεσιών ιστού πάνω σε ασύρματους αισθητήρες που έχουν την ίδια σημασιολογία με τις αντίστοιχες υπηρεσίες ιστού του DPWS. Εκτός τούτου, υποστηρίζει μία καινούρια φόρμα μηνυμάτων, η οποία στηρίζεται στην extensible markup language (XML) όπως και η φόρμα μηνυμάτων του DPWS. Τα Tiny SOAWS και DPWS υλοποιήθηκαν πάνω σε πραγματικούς ασύρματους αισθητήρες και συγκρίθηκαν μεταξύ τους χρησιμοποιώντας το αναπτυχθέν πειραματικό ΑΔΑ το οποίο είναι αποτελεί ένα πραγματικό 6LoWPAN ΑΔΑ με τον μέγιστο αριθμό των ασύρματων αισθητήρων του να είναι 12. Με σκοπό την επικύρωση των παραπάνω μετρήσεων, την επέκτασή τους σε μεγαλύτερης κλίμακας ΑΔΑ καθώς επίσης και τη σύγκρισης των 2 προαναφερθέντων στοιβών πρωτοκόλλων με ένα DPWS βασισμένο σε δυαδική κωδικοποίηση (binary-based DPWS), χρησιμοποιήθηκε το αναπτυχθέν εργαλείο προσομοίωσης το οποίο υλοποιήθηκε στον προσομοιωτή network simulator (NS)-2. Επιβεβαιώθηκε η ορθή λειτουργία του πειραματικού ΑΔΑ και του εργαλείου προσομοίωσης συγκρίνοντας τις μετρήσεις του ενός με τις μετρήσεις του άλλου. Το γεγονός αυτό επιτρέπει τη χρήση τους για την αξιολόγηση και σχεδίαση 6LoWPAN ΑΔΑ που υποστηρίζουν υπηρεσίες ιστού. Επιπλέον, η σύγκριση έδειξε ότι το Tiny SOAWS υπερτερεί του DPWS. Ωστόσο, το binary-based DPWS αποτελεί την καλύτερη επιλογή. Παρόλα αυτά, η εφαρμογή του περιορίζεται σε ασύρματους αισθητήρες με συγκεκριμένο λογισμικό καθώς το σύνολο των κανόνων της XML στο οποίο στηρίζονται οι υπηρεσίες ιστού για να προσφέρουν διαλειτουργικότητα στο επίπεδο εφαρμογής δεν χρησιμοποιείται πλέον. Τέλος, οι προβλέψεις του αναπτυχθέντος μαθηματικού μοντέλου για τον unslotted μηχανισμό του MAC υπο-επιπέδου του ΙΕΕΕ 802.15.4 προτύπου συγκρίθηκαν με μετρήσεις από τον NS-2 και βρέθηκε ότι αποκλίνουν ελάχιστα. Ως εκ τούτου, μπορεί να χρησιμοποιηθεί ως εργαλείο αξιολόγησης της σχεδίασης ΑΔΑ τα οποία μπορούν μετέπειτα να υποστηρίξουν την 6LoWPAN αρχιτεκτονική καθώς επίσης και υπηρεσίες ιστού.

Network Management Architecture

Traditional NM (Network Management) techniques can not be applied on WSN (Wireless Sensor Network) due to its features of low computing ability, tiny memory space, and limited energy. A new NMA (Network Management Architecture) for WSN is needed. In this paper, we design a loosely coupled NMA of WSN based on SOA (Service-Oriented Architecture), and have well defined NM interfaces. Finally, we develop a SOA platform for WSN operations according to the NMA. Based on SOA platform, users can compose and use various NM Web Services by internet depending on their requirements. Heavy tasks which need a great deal of computing resources and storage are executed on the SOA platform. Thus, energy consumption and node computation can be decreased. Moreover, external applications use Web Services to integrate SOA platform for WSN. It lowers the difficulty in integrating different sensor platforms and heterogeneous devices.

System architectures that deliver real-time services to customers must be flexible, scalable, and support a wide range of communication channels. This chapter presents an architecture that was designed to support multiple delivery channels and was successfully used to implement mobile banking services. The considerations behind the design and the approach used to deliver SMS-based mobile services using service-oriented architecture principles are reviewed and some of the practical challenges that were encountered with the implementation are explored. The ability for this solution architecture to support other real-time service channels is also examined.

Web services are playing a pivotal role in business, management, governance, and society with the dramatic development of the Internet and the Web. However, many fundamental issues are still ignored to some extent. For example, what is the unified perspective to the state-of-the-art of Web services? What is the foundation of Demand-Driven Web Services (DDWS)? This chapter addresses these fundamental issues by examining the state-of-the-art of Web services and proposing a theoretical and technological foundation for demand-driven Web services with applications. This chapter also presents an extended Service-Oriented Architecture (SOA), eSMACS SOA, and examines main players in this architecture. This chapter then classifies DDWS as government DDWS, organizational DDWS, enterprise DDWS, customer DDWS, and citizen DDWS, and looks at the corresponding Web services. Finally, this chapter examines the theoretical, technical foundations for DDWS with applications. The proposed approaches will facilitate research and development of Web services, mobile services, cloud services, and social services.
