A primary requirement in distributed robotic software systems is the dissemination of data to all interested collaborative entities in a timely and scalable manner. However, providing such a service in a highly dynamic and resource-limited robotic environment is a challenging task, and existing robot software infrastructure has limitations in this aspect. This paper presents a novel robot softw...

Quality-of-service enabled publish/subscribe (pub/sub) middleware provides powerful support for scalable data dissemination. It is difficult to maintain key quality of service properties (such as reliability and latency) in dynamic environments for distributed real-time and embedded systems (such as disaster relief operations or power grids). Managing quality of service manually is often not fe...

Service development and deployment face new challenges from the wide availability of Internet points of attachment, increasing deployment of wireless networks, and growing portabledevice market. To provision traditional Internet services to mobile clients, service providers must address the possibility of roaming during service sessions and the heterogeneity of access-terminal hardware and soft...

The Internet of Things (IoT) paradigm has given rise to a new class of applications wherein complex data analytics must be performed in real-time on large volumes of fast-moving, heterogeneous sensor-generated data. Such data streams are often unbounded and must be processed in a distributed and parallel manner to ensure timely processing and delivery to interested subscribers. Dataflow archite...

Middleware islands occur when an enterprise uses different middleware that doesn't communicate easily. They can arise because different middleware is used where it is most appropriate in an enterprise. Or the mix may have arisen for historical reasons, such as keeping up with new middleware developments, or because certain bought-in applications introduced their bundled middleware into the ente...

End-to-end predictability of remote operations is essential for many fixed-priority distributed real-time and embedded (DRE) applications, such as command and control systems, manufacturing process control systems, large-scale distributed interactive simulations, and testbeam data acquisition systems. To enhance predictability, the Real-time CORBA specification defines standard middleware featu...

Adaptation of distributed software to maintain the best possible application performance in the face of changes in available resources is an increasingly important and complex problem. In this paper, we discuss the application of the QuO adaptive middleware framework and the CORBA A/V Streaming Service to the development of real-time embedded applications. We demonstrate a standards-based middl...

Nowadays, storing the information is fundamental for the correct functioning of any organization. The critical factor is to guarantee the security of the stored data. In the traditional database systems the security requirements are limited to confidentiality, integrity, availability of the data and user authorization. The criticality of the database system and data repositories for modern busi...
