Software architectures play a significant role in the development of software-intensive
systems in order to allow satisfying both functional and non-functional requirements. In
particular, dynamic software architectures have emerged to address characteristics of the
contemporary systems that operate on dynamic environments and consequently subjected
to changes at runtime. Architecture description languages (ADLs) are used to represent
software architectures, producing models that can be used at design time and/or runtime.
However, most existing ADLs have limitations in several facets: (i) they are focused on
structural, topological aspects of the architecture; (ii) they do not provide an adequate
support for representing behavioral aspects of the architecture; (iii) they do not allow
describing advanced aspects regarding the dynamics of the architecture; (iv) they are
limited with respect to the automated verification of architectural properties and
constraints; and (v) they are disconnected from the implementation level, thus entailing
inconsistencies between architecture and implementation. In order to tackle these
problems, this thesis proposes formally founded framework for dynamic software
architectures. Such a framework comprises: (i) π-ADL, a formal language for describing
software architectures under both structural and behavioral viewpoints; (ii) the
specification of programmed dynamic reconfiguration operations; (iii) the automated
generation of source code from architecture descriptions; and (iv) an approach based on
statistical model checking (SMC) to formally express and verify properties in dynamic
software architectures. The main contributions brought by the proposed framework are
fourfold. First, the π-ADL language was endowed with architectural-level primitives for
describing programmed dynamic reconfigurations. Second, architecture descriptions in π-
ADL are translated towards implementation source code in the Go programming
language, thereby contributing to minimize architectural drifts. Third, a novel logic, called
DynBLTL, is used to formally express properties in dynamic software architectures.
Fourth, a toolchain relying on SMC was built to automate the verification of architectural
properties while striving to reduce effort, computational resources, and time for
performing such a task. In this work, two wireless sensor network-based systems are used
to validate the framework elements. |

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Arquiteturas de software exercem um papel significativo no desenvolvimento de sistemas intensivos de software a fim de permitir satisfazer tanto requisitos funcionais quanto nãofuncionais. Em particular, arquiteturas de software dinâmicas têm surgido para endereçar características dos sistemas contemporâneos que operam em ambientes dinâmicos e consequentemente sujeitos a mudanças em tempo de execução. Linguagens de descrição arquitetural (ADLs) são utilizadas para representar arquiteturas de software, produzindo modelos que podem ser utilizados tanto em tempo de projeto quanto em tempo de execução. Contudo, a maioria das ADLs existentes possui limitações em diversos aspectos: (i) possui enfoque em aspectos estruturais, topológicos da arquitetura; (ii) não provê um suporte adequado à representação de aspectos comportamentais da arquitetura; (iii) não permite descrever aspectos avançados relativos à dinâmica da arquitetura; (iv) é limitada com relação à verificação de propriedades arquiteturais e restrições, e; (v) é desconectada do nível de implementação, resultando em inconsistências entre arquitetura e implementação. No intuito de endereçar esses problemas, esta tese propõe um framework formal para arquiteturas de software dinâmicas. Tal framework envolve: (i) π-ADL, uma linguagem formal para descrever arquiteturas de software sob as perspectivas estrutural e comportamental; (ii) a especificação de operações de reconfiguração dinâmica programada; (iii) a geração automática de código fonte a partir de descrições arquiteturais, e; (iv) uma abordagem baseada em verificação estatística (SMC) para expressar e verificar formalmente propriedades em arquiteturas de software dinâmicas. As principais contribuições trazidas pelo framework proposto são quatro. Primeiro, a linguagem π-ADL passou a ser dotada de primitivas de nível arquitetural para descrever reconfigurações dinâmicas programadas. Segundo, descrições arquiteturais em π-ADL são traduzidas para código fonte de implementação na linguagem de programação Go, contribuindo assim para minimizar desvios arquiteturais. Terceiro, uma nova lógica chamada DynBLTL é utilizada para expressar formalmente propriedades em arquiteturas de software dinâmicas. Quarto, um ferramental baseado em SMC foi construído para automatizar verificação de propriedades arquiteturais enquanto busca reduzir esforço, recursos computacionais e tempo para realizar essa tarefa. Neste trabalho, dois sistemas baseados em redes de sensores sem fio são utilizados para validar os elementos do framework. 2017-08-14T11:42:00Z 2017-08-14T11:42:00Z 2016-06-10 doctoralThesis CAVALCANTE, Everton Ranielly de Sousa.
