A Quality-Driven Iterative Evolution Approach for Software Architecture

The quality attributes of software architecture (SA) determine whether SA can be easily understood, tested, modified and so on, so quality-driven architecture evolution is important for keeping the viability and competitiveness. SA evolution is a process, and it contains multiple steps, such as SA quality measurement, SA modification, code co-evolution and so on. In order to guarantee that the software can be continuously improved and iteratively evolved in the future, we need to focus on all steps. However, most existing approaches only focus on one aspect, so they did not pay attention to how to finish the evolution process. In this paper, we propose a quality-driven iterative evolution approach for SA. This approach focuses on the whole process. In the first step, we use a quantitative approach to measure the architecture quality. Then, we construct the conflict graph to detect conflicts between evolution requirements to generate the final evolution scheme. In the third step, we modify architecture based on the evolution scheme. Finally, we co-evolve file dependency graph (FDG) based on the modified architecture. By focusing on the above steps, our approach can support a complete quality-driven architecture evolution process and obtain the maximum benefit in terms of the combined SA quality. We conduct our experiments with four open source projects, the experimental results indicate that our approach can improve SA quality, and our approach can effectively co-evolve the FDG to lay the foundation for the next evolution.

Decision Support System for Fitting and Mapping Nonlinear Functions with Application to Insect Pest Management in the Biological Control Context

The process of moving from experimental data to modeling and characterizing the dynamics and interactions in natural processes is a challenging task. This paper proposes an interactive platform for fitting data derived from experiments to mathematical expressions and carrying out spatial visualization. The platform is designed using a component-based software architectural approach, implemented in R and the Java programming languages. It uses experimental data as input for model fitting, then applies the obtained model at the landscape level via a spatial temperature grid data to yield regional and continental maps. Different modules and functionalities of the tool are presented with a case study, in which the tool is used to establish a temperature-dependent virulence model and map the potential zone of efficacy of a fungal-based biopesticide. The decision support system (DSS) was developed in generic form, and it can be used by anyone interested in fitting mathematical equations to experimental data collected following the described protocol and, depending on the type of investigation, it offers the possibility of projecting the model at the landscape level.

This will allow professors to develop their research, training, teaching and presentation of timely reports, with the measurement of achieved skills and abilities of students, managers and academic authorities, and to make decisions based on the results obtained by the tool allowing an improvement in the quality of the contents and development flow of the syllabus.

Modelo de requerimientos y de funcionalidad de software basado en MDA y UML para la gestión de proyectos y convenios globales

Modelo de requerimientos y de funcionalidad de software basado en MDA y UML para la gestión de proyectos y convenios globales Luis Alberto Lujan Campos Escuela de Post Grado, Universidad Nacional Federico Villarreal, Jr. Camana 1014, Lima, Perú Recibido el 01 de junio del 2017. Aceptado el 1 de julio del 2017 DOI: https://doi.org/10.33017/RevECIPeru2017.0002/ Resumen El propósito es elaborar modelos de la arquitectura que son independientes de la plataforma de software para la gestión de información de proyectos y convenios globales. Que sean orientados por el enfoque Model Driven Architecture (MDA, Arquitectura Dirigida por Modelos) que puede ayudar a resolver al mismo tiempo tanto los problemas de la industrialización y las infraestructuras de software en constante cambio [1]. Este enfoque de arquitectura de software promueve la separación de la especificación de la funcionalidad de la implementación de esta funcionalidad en plataformas específicas. En la arquitectura del sistema de software para la gestión de proyectos y convenios globales se determinó los módulos principales: módulo de cooperantes, módulo de datos del proyecto o convenio, módulo de presupuesto, módulo de finanzas y módulo de seguimiento de actividades y se logró elaborar los siguientes modelos: requisitos, estructura de clases de objetos y de secuencia. Estos modelos son los conductores primarios en todos los aspectos del desarrollo de software. Los modelos tienen diversas vistas como: Modelo de la estructura del sistema y de la funcionalidad de los módulos. Para la elaboración de los modelos se ha utilizado el Unified Modeling Language (UML, Lenguaje Unificado de Modelado). UML es un lenguaje de modelado y no un método, es la notación (principalmente gráfica) del que se valen los métodos para expresar los diseños y que en el proceso de software es la orientación que nos dan sobre los pasos a seguir para hacer el diseño [2]. Descriptores: Arquitectura Dirigida por Modelos, Lenguaje Unificado de Modelado, Diseño de software Abstract The purpose is to develop architecture models that are independent of the software platform for the management of information of global projects and agreements. That is guided by the Model Driven Architecture (MDA) approach that may help solving at the same time both problems of industrialization and ever-changing software infrastructures [1]. This software architecture approach promotes the separation of the specification from the functionality of the implementation of this functionality into specific platforms. In the architecture of the software system for the management of global projects and conventions, the main modules were determined: cooperators module, data module of the project or agreement, budget module, finance module and activity tracking module and elaboration The following models: requirements, structure of object classes and sequence. These models are the primary drivers in all aspects of software development. The models have different views such as: Model of the structure of the system and the functionality of the modules. For the elaboration of the models the Unified Modeling Language (UML) has been used. UML is a modeling language and not a method, it is in the notation (mainly graph) of which the methods are used to express the designs and that in the software process is the orientation that they do not give on the steps to follow to do the design [2]. Keywords: Model Driven Architecture (MDA), Unified Modeling Language (UML), Software Design

Towards a formal verification approach for cloud software architecture

Behavioral consistency of cloud architectures is one of the pivotal challenges in cloud computing. In this paper, we propose a new approach for checking the behavioral consistency of the topology and orchestration of cloud computing. To do so, we choose TOSCA language in order to describe the cloud application. Then, we exploit the Wright ADL that encompasses the CSP language to check the consistency of cloud architectures using FDR2 model-checker.

Towards a hybrid software architecture and multi-agent approach for autonomous robot software

To support robust plan execution of autonomous robots in dynamic environments, autonomous robot software should include adaptive and reactive capabilities to cope with the dynamics and uncertainties of the evolving states of real-world environments. However, conventional software architectures such as sense-model-plan-act and behaviour-based paradigms are inadequate for meeting the requirements. A lack of sensing during acting in the sense-model-plan-act paradigm makes the software slow to react to run-time contingencies, whereas the behaviour-based architectures typically fall short in planning of long-range steps and making optimized plan adaptations. This article proposes a hybrid software architecture that maintains both adaptivity and reactivity of robot behaviours in dynamic environments. To implement this architecture, we further present the multi-agent development framework known as AutoRobot, which views the robot software as a multi-agent system in which diverse agent roles collaborate to achieve software functionalities. To demonstrate the applicability and validity of our concrete framework and software architecture, we conduct an experiment to implement a typical case, for example, a robot that autonomously picks up and drops off dishes for remote guests, which requires the robot to plan and navigate in a highly dynamic environment and can adapt its behaviours to unexpected situations.

Z-Monitor: A protocol analyzer for IEEE 802.15.4-based low-power wireless networks

Network sniffers are invaluable tools for designing, testing, commissioning and running distributed embedded systems. They become even more useful if these systems build on low-power wireless networks (LoWPAN), particularly when these scale in density and/or space and impose stringent quality-of-service requirements. This paper presents Z-Monitor, a low-cost and open-source network/protocol analyzer for LoWPANs. Z-Monitor is better than existing solutions since it combines the following features all-together: it covers the most widely used LoWPAN protocols, namely IEEE 802.15.4, 6LoWPAN, RPL and ZigBee; packet sniffing can be performed by any IEEE 802.15.4-compliant node, e.g., TelosB or MicaZ, requiring no extra hardware; the code is in Java (host PC), so it is OS-agnostic, and is freely available as open-source; Z-Monitor provides an user-friendly graphical user interface and a complete set of functionalities; nonetheless, Z-Monitor software architecture and programming approach are modular, so it is easily adaptable and extensible. We demonstrate and validate Z-Monitor in several LoWPAN network scenarios/settings and sites, ranging from a small-scale laboratory test-bed to a 400+ real-world deployment.

Research on Measurement Technique for Evaluating Adaptability of Aspect-Oriented Software Architecture

The design and description approach for aspect-oriented software architecture (AOSA) has made great progress in the past several years. However, there are few efficient techniques or approaches for evaluating adaptability of AOSA. According to the characteristics and running environments of software system nowadays, this paper proposes quantitative measurement technique for evaluating adaptability of AOSA based on class point (CP) and the feature of AC2-ADL. This technique can provide support of measurement for aspectual component and aspectual connector in AC2-ADL. In the future, we will accomplish an approach for evaluating adaptability of AOSA based on this measurement technique.

Toward a Software Architectural Design Approach for Trusted Software Based on Monitoring

Nowadays,the trustworthiness has become the noticed focus in qualities of software,which emphasizes analysis,measurement,corresponding applications and support environments for the trustworthiness quality.Injecting monitoring capacity into software can be one of the approaches to improve the credibility of software.However,the current work primarily concentrates on the programming and coding level,lacking a systematic architectural design approach to guide the whole design and analysis process for the trusted software.By introducing aspect-oriented architectural design approach and relevant techniques into the design and analysis of software,this paper tries to offer an effective and systematic solution for the trusted software system.Based on trusted software constitution model with the capability of monitoring,the proposed approach utilizes a special kind of aspect-oriented architecture description language AC2-ADL to depict such software system,contributing to comprehension,evolution and reusability of software architectural design decisions.Summarily,the whole designing process of the approach is discussed systematically through a case study in e-business domain.

Towards service-based approach: building huge software architectural design

Software architecture, as a discipline, draws vocabulary like rules, paradigm, pattern that help to build software systems. In this paper we first provide an introduction to the emerging field of software architecture. Many software architecture approaches were introduced; they draw different paths and methodologies to build software systems. This paper forms a survey for some of these approaches with a focus on the decomposition approach in terms of requirements and data-attributes. In this paper we will discuss a new formal service-based software decomposition approach. This approach consists of a micro-phased process. We begin by considering the front-end services, the common and modern architectural styles upon which many systems are currently based; we focus on their business profiles, non-atomic business data-items and business rules. Our proposed approach represents the first and crucial design stage in the software engineering process. It consists of building the overall software architectures that could be represented as an oriented and purposed graph. At the end, we demonstrate that the process is plausible and easy to apply. We also state that micro-phases may be reiterated and executed without strict ordering. Meta-modelling and computerising such approach represents our future works.

A new approach for component’s port modeling in software architecture

The component’s interaction points with the external world play a fundamental role in the specification of an application’s architecture. Current software architecture approaches consider an interaction point as an atomic element in the specification of interconnections, despite the complexity of its structure and the attached behavior. It is not possible in current component models to deal separately with an element of an interaction point when such an element is needed alone for specifying a specific logic. To support such logic and the specification of a wide range of early ideas in the process of elaborating a software system, the Integrated Approach to Software Architecture (IASA) uses an interaction point model which provides facilities to manipulate any structural or behavioral element defining an interaction point. In addition, such facilities represent the fundamental foundation of the native support by IASA of Aspect Oriented Software Architectures (AOSA) specifications.

Ambient-PRISMA: Ambients in mobile aspect-oriented software architecture

This work presents an approach called Ambient-PRISMA for modelling and developing distributed and mobile applications. Ambient-PRISMA enriches an aspect-oriented software architectural approach called PRISMA with the ambient concept from Ambient Calculus. Ambients are introduced in PRISMA as specialized kinds of connectors that offer mobility services to architectural elements (components and connectors) and are able to coordinate a boundary, which models the notion of location. Mobility of architectural elements is supported by reconfiguring the software architecture. This paper presents a metamodel that introduces ambients to design aspect-oriented software architectural models for mobile systems. The design of models is performed using an Aspect-Oriented Architecture Description Language. A middleware called Ambient-PRISMANET which maps the metamodel to .NET technology and supports the distributed runtime environment needed for executing mobile applications is also presented. In addition, a CASE Tool which allows users to specify the aspect-oriented architectural models in a graphical way and generate .NET code is provided. In this way, we explain how Ambient-PRISMA follows Model Driven Engineering. An example of an auction system is used throughout the article to illustrate the work.

Component-based architecture: the Fractal initiative

Component-based software engineering (CBSE) [32] and software architecture [30] have become mature and very active fields of study. Both can be traced back to an early vision of systematically produced software [24] and are primarily concerned with the construction of software systems by composition or assembly of software components, with well-defined interfaces and explicit dependencies. Nowadays, it is generally recognized that component-based software engineering and software architecture approaches are crucial to the development, deployment, management, and maintenance of large, dependable software systems [6]. Several component models and associated architecture description languages (i.e., notations for defining components and component assemblages) have been defined in the past 15 years. In large part, this diversity stems from differences in application domains targeted by the different models, as well as differences in choices for component interconnection and composition capabilities (much as there exists today a wealth of models and languages for concurrency). In the face of this diversity, the Fractal component model [10]—a programming language-independent component model for the construction of highly configurable software systems introduced by France Telecom and INRIA in 2001—was designed from the outset to allow arbitrary forms of component interconnection and component composition and to allow other component models to be derived as Fractal personalities. To achieve this, the Fractal model combines ideas from three main sources: (1) CBSE and software architecture, (2) reflective systems [18], and (3) configurable and adaptable distributed systems, (notably, the OpenORB [7] system and its associated OpenCOM component model [12]). From CBSE and software architecture, Fractal inherits basic concepts for the modular construction of software systems: software components, interfaces, and explicit connections (called bindings) between them. Notably, these concepts allow for the (recursive) construction and management of hierarchical component architectures possibly with sharing (a subcomponent can be part of several parent components) this last feature being an originality of Fractal. From reflective systems, Fractal inherits the idea that components can exhibit meta-level behavior reifying, through appropriate interfaces (called controller interfaces), their internal structure, and behavior.
