Abstract The article presents the watercraft recognition and identification system as an extension for the presently used visual water area monitoring systems, such as VTS (Vessel Traffic Service) or RIS (River Information Service). The watercraft identification systems (AIS - Automatic Identification Systems) which are presently used in both sea and inland navigation require purchase and installation of relatively expensive transceivers on ships, the presence of which is not formally required as equipment of unconventional watercrafts, such as yachts, motor boats, and other pleasure crafts. These watercrafts may pose navigation or even terrorist threat, can be the object of interest of the customs, or simply cause traffic problems on restricted water areas. The article proposes extending the traffic supervision system by a module which will identify unconventional crafts based on video monitoring. Recognition and identification will be possible through the use of image identification and processing methods based on artificial intelligence algorithms, among other tools. The system will be implemented as independent service making use of the potential of SOA (Service Oriented Architecture) and XML/SOAP (Extensible Markup Language/Simple Object Access Protocol) technology.

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.

In order to build a low-latency and light-weight publish/subscribe (pub/sub) system for delay-sensitive IOT services, the authors propose an efficient and scalable broker architecture named Grid Quorum-based pub/sub (GQPS). As a key component in Event-Driven Service-Oriented Architecture (EDSOA) for IOT services, this architecture organizes multiple pub/sub brokers into a Quorum-based peer-to-peer topology for efficient topic searching. It also leverages a topic searching algorithm and a one-hop caching strategy to minimize the search latency. Light-weight RESTful interfaces make the authors’ GQPS more suitable for IOT services. Cost analysis and experimental study demonstrate that the GQPS achieves a significant performance gain in search satisfaction without compromising search cost. The authors apply the proposed GQPS in the District Heating Control and Information Service System in Beijing, China. This system validates the effectiveness of GQPS.

Web Services (WS) technologies, generally built around the ubiquitous Extensible Markup Language (XML), have provided many opportunities for integrating enterprise applications. However, XML/Simple Object Access Protocol (SOAP), together with Web Services Definition Language (WSDL) and Universal Description Discovery and Integration (UDDI), form a comprehensive suite of WS technologies that have the potential to transcend beyond mere application integration within an organization, and to provide capabilities of integrating processes across multiple organizations. Currently, the WS paradigm is driven through parameters however; the paradigm shift that can result in true collaborative business requires us to consider the business paradigm in terms of policies-processes-standards. This chapter, based on experimental research carried out by the authors, demonstrates how the technologies of WS open up the doors to collaborative Enterprise Architecture Integration (EAI) and Service Oriented Architecture (SOA) resulting in Business Integration (BI). The chapter also provide a quantitative investigation based on organization’s adaptation to mobile and Web Services technologies.

Abstract Lifelong learning requires appropriate solutions, especially for corporate training. Workers usually have difficulty combining training and their normal work. In this context, micro-learning emerges as a suitable solution, since it is based on breaking down new concepts into small fragments or pills of content, which can be consumed in short periods of time. The purpose of this paper is twofold. First, we offer an updated overview of the research on this training paradigm, as well as the different technologies leading to potential commercial solutions. Second, we introduce a proposal to add micro-learning content to more formal distance learning environments (traditional Learning Management Systems or LMS), with the aim of taking advantage of both learning philosophies. Our approach is based on a Service-Oriented Architecture (SOA) that is deployed in the cloud. In order to ensure the full integration of the micro-learning approach in traditional LMSs, we have used two well-known standards in the distance learning field: LTI (Learning Tools Interoperability) and LIS (Learning Information Service). The combination of these two technologies allows the exchange of data with the LMS to monitor the student’s activity and results. Finally, we have collected the opinion of lectures from different countries in order to know their thoughts about the potential of this new approach in higher education, obtaining positive feedback.

Effective Assessment

In order to avoid collision, ships usually take collision avoidance manoeuvres, such as course alteration. However, the effect of such a manoeuvre is influenced by ship manoeuvrability. This paper proposed an improved danger sector model to identify the collision risk between two encountering ships. The proposed model is improved from the danger sector model, which is based on a course alteration manoeuvre by taking ship manoeuvrability into consideration. To involve ship manoeuvrability in the proposed model, the turning circle of a ship is determined when it calculates the size of the danger sector. For validating the proposed model, the Automatic Identification System (AIS) data in the northern Yellow Sea of China were used to carry out some experiments of different encountering scenarios. The results show that the proposed improved danger sector model can identify the collision risk between two encountering ships effectively and has advantages compared with the original danger sector model. The proposed model can help mariners and maritime surveillance operators have a more accurate and effective assessment of ship collision risk in the water area, which can contribute to the improvement of navigational safety.
