The diverse requirements of wireless sensor network applications necessitate the development of multiple media access control (MAC) protocols to meet their varying throughput, latency, and network lifetime needs. Building new MAC protocols has proven ...

A frame is an archetype—a model from which all similar things are made. Frame technology can synthesize any information structure (such as a program) from machine-adaptable frames. The author contrasts FT with object-oriented classes. By canonically ...

Object-oriented software development practices are being rapidly adopted within increasingly complex systems, including reactive, real-time and concurrent system applications. While data modeling is performed very well under current object-oriented development ...

In this paper, we describe the design and development of a simulation-agent interface for real-time distributed control system benchmarking. This work is motivated by the need to test the feasibility of extending agent-based systems to the physical device ...

This position paper concerns formal methods for developing safe service-oriented architectures (SOAs) with support for resource management. We seek an approach to building such SOAs based on the specification of service requirements as declarative contracts, ...

The extraordinary growth of the Information Society is originating a high dependency on ICT. This provokes that those strongly interrelated technological infrastructures, as well as the information systems that underpin them, become highly critical, ...

Location systems are core technologies for enabling pervasive computing smart spaces. Signal Strength based location estimation offers economical viability and sufficient accuracy for numerous location based services. Despite extensive research being ...

Service-oriented architectures are increasingly used in the context of business processes. However, the proven practices for process-oriented integration of services are not well documented yet. In addition, modeling approaches for the integration of ...

Search by a customized and dynamic SOA can provide the greater precision, relevancy, semantic awareness, and adaptivity the enterprise requires.

Due to the pervasive nature of current short range, low-power wireless connectivity and easy availability of low-cost light weight mobile devices, it is necessary to have an omnipresent customizable service. It can be used by different types of users ...

Process Managers are applications that implement and manage process flows integrating people, information, and technology. They allow customers to improve organizational productivity while satisfying governance and compliance requirements. This paper ...

Metamodelling provides a way of modelling the rules underpinning not only modelling languages such as UML but also processes. In the context of object-oriented development, we evaluate the conceptual framework used to reason about metamodelling from ...

FlexTV is a reference middleware platform developed in the context of the Brazilian Digital TV project. The first FlexTV version did not use a component model which could make it possible to reconfigure the middleware at runtime. This paper presents ...

Has Software Architecture-based testing any characteristic which makes it unique with respect to other testing techniques? This recurrent question will be analyzed in this short paper, providing some initial solution, while leaving ample space for discussion.

Refactoring is the process of making changes to the internal structure of existing code without changing the external behavior of that code. The resulting code is more flexible, reusable, and maintainable. While refactoring is becoming more popular in ...

In recent years, Aspect-Oriented Software Development (AOSD) has emerged as a new technology addressing separation of concerns. However, this technology has not been widely adopted in real life scenarios mainly due to the lack of a clear AOSD methodology/process, ...

The Semantic Web is about a Web which contains data which is machine-processable rather than human-interpretable. This makes new demands upon the Web architecture such as a standardized interface for access to this knowledge (how to interact), model ...

The Enterprise Service Bus (ESB) is the infrastructure which underpins a fully integrated and flexible end-to-end service-oriented architecture (SOA). This paper details the essential meta-data and capabilities of the ESB. It presents a summary of the ...
