Um middleware extensível para disponibilização de serviços em ambientes pervasivos.

Abstract

The advances in hardware and wirelessnetworking technology have enabled the realization of so-called paradigm of pervasive computing, also known as ubiquitous computing. Insuch a paradigm, computing is embedded in everyday objects like cars, televisions, and clothes, so that it can be transparently integrated into ourl ives. Due to such advances, research in the field of pervasive computing is increasing in a fast pace, as it is now possible to create the first environments and applications contemplating its characteristics. Within this scope, the development of pervasive computing applications involves a set of intricacies not directly related to them. Networking communication, acquisition of context information, and security to name some. However, it is clearly more obvious to let developers concentrate entirely on the application logic, freeing them of dealing with such intricacies. With such an idea in mind, it has been proposed software infrastructures known as middlewares. One of the approaches that has been successfully used in the development of middlewares for pervasive computing is the service oriented computing paradigm. Besides, features like context awareness, host discovery, and dynamic evolution also emerge as important elements concerning such middlewares. Given this trend, the main goal of this work is the development of a pervasive computing middleware, named of Wings, contemplating the mentioned features.
