A Service-Oriented Approach for Network-Centric Data Integration and Its Application to Maritime Surveillance

Abstract

Maritime-surveillance operators still demand for an integrated maritime picture better supporting international coordination for their operations, as looked for in the European area. In this area, many data-integration efforts have been interpreted in the past as the problem of designing, building and maintaining huge centralized repositories. Current research activities are instead leveraging service-oriented principles to achieve more flexible and network-centric solutions to systems and data integration. In this direction, this article reports on the design of a SOA platform, the "Service and Application Integration" (SAI) system, targeting novel approaches for legacy data and systems integration in the maritime surveillance domain. We have developed a proof-of-concept of the main system capabilities to assess feasibility of our approach and to evaluate how the SAI middleware architecture can fit application requirements for dynamic data search, aggregation and delivery in the distributed maritime domain.

A DHT-Based Discovery Service for the Internet of Things

“…IoT applications should adapt their behaviour to changes in an extremely dynamic environment: users enter and exit from "smart environments" (e.g., smart homes [3][4][5], smart hospitals [6][7][8], smart offices [9,10], and tourism locations [11,12]), objects change their position according to specific application purposes (e.g., mobility of persons [13,14], multimodal transport of goods [15], and maritime surveillance [16]). Discovery mechanisms are thus required in order to obtain up-to-date information about functional capabilities offered by devices distributed in the environment or information repositories storing information about a given object.…”

A Dynamic Composition and Stubless Invocation Approach for Information-Providing Services

“…In order to validate the effectiveness of our Service Profile Model in enabling dynamic service composition and invocation in a working environment, we developed a prototype that serves as a proof of concept. This prototype exploits and extends the capabilities provided by a middleware infrastructure, the Service and Application Integration (SAI) system, developed in our research laboratory [33] [34]. SAI is written in Java and implements many SOA principles and design patterns.…”

“…Registration is not restricted solely to services whose interface complies with the WSDL specification. External systems may also be accessed through customized Adaptor components that expose message-based interfaces [33].…”

Toward a Cooperative Approach for Continuous Innovation of Mobility Information Services

“…In this context, research objectives consist in achieving: a) an extreme degree of configurability; b) dynamic service discovery, invocation and composition capabilities [40]; c) specification and enactment of distributed security policies. We refer the reader to [41] for a detailed description of recent results in the design and development of this middleware.…”
