Middleware is a communication software placed (usually atop TCP or UDP)
between the application and the operating system in order to hide the
complexity of underlying network mechanisms. This fact enormously facilitates
the task of distributed application developers as the middleware is viewed as a
collection of distributed services (or middleware services) that takes the
primary responsibility of communicating distributed applications. The
middleware often also provides additional services such as security,
transaction, naming and events, which “aggregate” value to the communication
between distributed applications.
My research interests include the development
of (1) middleware systems and (2) service oriented computing (SOC) with
emphasis on the project, design and implementation of middleware systems and
web service composition. Middleware systems include ones running on desktops, mobile
phones and sensor nodes, which may
adopt different communication models such client-server,
publish-subscribe and tuple spaces. In terms of
SOC, my research focuses on the composition
of web services regarding quality attributes and dynamic adaptation.
Projects ▲
►Development of Middleware Frameworks
(FACEPE / CPNq) [2007-2008] (In
Portuguese)
O objetivo geral deste projeto é desenvolver um
suporte integrado para construção de sistemas de middleware.
Para alcançarmos este objetivo geral, três objetivos específicos devem ser
alcançados: definição de um conjunto de componentes básicos de middleware; desenvolvimento de um framework de implementação; e desenvolvimento de um framework de
formalização. Estes frameworks serão desenvolvidos utilizando-se princípios de
arquitetura de software. Os elementos utilizados como base para os dois
frameworks são elementos arquiteturais que incluem componentes (elementos de
computação), conectores (elementos de comunicação), configuração (composição de
componentes e conectores) e estilos (restrições na composição
composição). Estes frameworks funcionarão como
uma pré-implementação para a construção de middleware e como templates
(semi-especificações) para a formalização
►Middleware Framework for Mobile
Devices (FINEP) [2007-2009]
|
This project focuses on developing a device middleware implemented in
Java that supports heterogeneous application models (Java and C++), in order
to access typical embedded application problems, such as, runtime updates,
component orientation, and execution environment heterogeneity. |

) [2008-2009] (In Portuguese)Teaching ▲
