Commercial off-the-shelf (COTS) distribution middleware is gaining acceptance in the distributed real-time and embedded (DRE) community. Existing COTS specifications, however, do not effectively separate quality of service (QoS) policy configurations and adaptations from application functionality. DRE application developers therefore often intersperse code that provisions resources for QoS guar...

THREAD is a research project aimed at providing an integral support for the development of embedded real-time systems. The support elements that are being developed in the project include a family of inter-operable execution platforms, their inter-connection mechanisms, and the applicable architecture and design methodologies. Some new-generation application domains for this kind of systems are...

Service oriented middleware draws a lot of attention in current research on sensor networks. The automatic distribution of services within a network and the preservation of this distribution is a fundamental aspect of network applications with self-x properties. The network gains the ability to react on mobility, network fragmentation, node failures and new user demands. This paper proposes a d...

Nowadays, it is crucial to preserve the privacy of end-users while utilizing a third-party recommender service within content distribution networks so as to maintain their satisfaction and trust in the offered services. The current business model for those recommender services is centered around the availability of users’ personal data at their side whereas consumers have to trust that the reco...

Abstract Securing distributed device communication is critical because the private industry and military depend on these resources. One area that adversaries target middleware, which medium connects different systems. This paper evaluates a novel security layer, DDS-Cerberus (DDS-C), protects in-transit data improves efficiency data-first distribution research contributes robotics operating sys...

Multimedia applications using broadband networking technologies (for example, Asynchronous Transfer Mode) often require services not provided by standard transport layer middleware, such as TCP or TP4. A broadband transport service must provide support for QoS (quality of service) control, multiparty control, synchronization, packet sequence reconstruction, and direct data-link access. Manageme...

Pervasive Computing is becoming feasible. Service discovery and communication protocols now make it possible to build pieces of software that can be dynamically composed into distributed applications. However, when designing such software, developers must often write code related to distribution and discovery aspects. This non-functional code results in higher development costs and may raise in...

Locality of referenced data is an important aspect for distributed computing. Caching is commonly employed to achieve this goal. However, when using current component-oriented middleware client application programmers have to take care of this non-functional aspect by themselves, without direct support from middleware facilities or design tools. The paper at hand describes a novel approach to d...
