Software deployment architecture and quality-of-service in pervasive environments

ABSTRACT

Over the past several years we have investigated two problems related to the domain of highly distributed, mobile, resource constrained, embedded, and pervasive environments: software deployment and quality of service (QoS). We have done so with the explicit focus on the role played by software architecture in deployment, and on its relationship to QoS. In the process, we have amassed a body of knowledge and experience, and assembled a suite of solutions for targeting different facets of the interplay among software architecture, deployment, and QoS. At the same time, the area we are addressing has proven to be multi-faceted and very complex, constantly presenting new challenges. In this paper we outline the contours of the problem of QoS in architecture-based deployment, our strategy for addressing it, and the challenges that remain. We view this as an important (and fruitful) area of research.
