  • ANSI/IEEE 1471 and Systems Engineering•
    ANSI/IEEE 1471 and Systems Engineering• Mark W. Maier David Emery The Aerospace Corporation The MITRE Corporation 15049 Conference Center Dr 7515 Colshire Drive, MS N110 Chantilly, VA 20151 McLean, VA 22102-3481 [email protected] [email protected] Rich Hilliard P.O. Box 396 Littleton, MA 01460 [email protected] Abstract: ANSI/IEEE Standard 1471-2000 is the Recommended Practice for Architectural Description of Software- Intensive Systems, developed by the IEEE’s Architecture Working Group (AWG) under the sponsorship of the Software Engineering Standards Committee of IEEE. ANSI/IEEE 1471 is the first formal standard1 to address the content and organization of architectural descriptions. The standard defines the structure and content of an architectural description (AD) and incorporates a broad consensus on best practices for such descriptions. Although ANSI/IEEE 1471 was conceived as a software-focused standard, this paper argues that it is equally applicable to any system; hence appropriate for use as a part of systems engineering to describe system architectures. This article reviews the concepts of ANSI/IEEE 1471, the rationale for their selection, and demonstrates its application in systems engineering. ARCHITECTURE FRAMEWORKS The notion of architecture has entered into both the domains of software and systems engineering in recent decades. There are several threads to this entry. Many invoke a direct analogy with the notion in civil engineering, while others are built on particular practices largely drawn from the information technology industry. Some background on what problems are being addressed by what goes by the term “architecture” is helpful in understand the motivation for the ANSI/IEEE 1471 work and related frameworks.

It exists in different systems requires appropriate methods and techniques to support forms depending on the applied industrial or application the development including the specification and analysis of domain. According to IEEE 1471 standard [3], an architecture different architectural aspects. A large number of architectural is defined as: description languages (ADL) have been proposed with varying focus and application domains. There is a need for “The fundamental organization of a system embodied in its harmonization of these ADLs. This can be from develoloping and components, their relationships to each other, and to the understanding of how they differ or could be synergistically environment and the principles guiding its design and combined for increasing the overall development efficiency and evolution” fulfilling the ever increasing functional and non-functional requirements on a system. This paper addresses this issue and While an architectural description is the specification of an focuses on four different ADLs: EAST-ADL, AUTOSAR, AADL architecture, an ADL provides the syntax, either textual or and Rubus. In this work we compare these ADLs, identify graphical, for an architecture description. The need for possible usage scenarios involving more than one ADL and expressing and describing architectures of real-time embedded discuss some of the underlying challenges.

    “SIMULATION OF BASIC MULTI-HOP BROADCAST TECHNIQUES IN VEHICULAR Ad-Hoc NETWORKS USING VEINS SIMULATOR” A Master's Thesis Submitted to the Faculty of the Escola Tècnica d'Enginyeria de Telecomunicació de Barcelona Universitat Politècnica de Catalunya by David Leonardo Renjifo Herrera In partial fulfilment of the requirements for the degree of MASTER IN TELECOMMUNICATIONS ENGINEERING Advisor: Mónica Aguilar Igartua Co-Advisor: Cristhian Iza Barcelona, February 2016 Title of the thesis: “Simulation of basic multi-hop broadcast techniques in Vehicular Ad-hoc Networks using VEINS simulator”. Author: David Leonardo Renjifo Herrera Advisor: Mónica Aguilar Igartua Co-advisor: Cristhian Iza Abstract This project presents to the reader an incursion into the world of smart cities and vehicles, intelligent transport systems, and vehicular ad-hoc networks (VANETs). They are conceptually analyzed, studied in terms of requirements, framework, architecture, applications and standardization. The main objective of this project is the simulation of basic techniques of message dissemination in VANETs, this project shows a brief description of broadcast dissemination techniques. Also, it is necessary to analyze simulation of VANETs. For this reason, it presents a brief description of mobility generators, network simulators and VANETs simulators paying attention to the open source ones. The main focus is set on the VEINS simulation framework, due to its high performance results and a bidirectional coupling between the network and the traffic simulators. From that point, the project is aimed at analyzing the basic paradigms of VEINS components (OMNeT++, SUMO and the TraCI module) and providing a study on their features. Three techniques are simulated (Flooding, Counter and Probability schemes) in two different scenarios (urban and highway), the simulation results are shown focused on the amount of retransmitting nodes, percentage of reached nodes, amount of packets sent, average packet delay, and percentage of packets received.

  • Software Architectures for Healthcare Cyber-Physical Systems: a Systematic 3 Literature Review
    1 2 Software Architectures for Healthcare Cyber-Physical Systems: A Systematic 3 Literature Review 4 Andrea M. Plaza+,*, Jessica Díaz+, Jennifer Pérez+ 5 +Universidad Politécnica de Madrid-CITSEM, Madrid, Spain 6 *Universidad Politécnica Salesiana, Cuenca, Ecuador 7 [email protected], [email protected], [email protected] 8 9 Abstract. Cyber-Physical Systems (CPS) refer to the next generation of ICT systems that mainly integrate sensing, 10 computing, and communication to monitor, control, and interact with a physical process to provide citizens and busi- 11 nesses with smart applications and services: healthcare, smart homes, smart cities, and so on. In recent years, healthcare 12 has become one of the most important services due to the continuous increases in its costs. This has motivated extensive 13 research on healthcare CPS, and some of that research has focused on describing the software architecture behind these 14 systems. However, there is no secondary study to consolidate the research. This paper aims to identify and compare 15 existing research on software architectures for healthcare CPS in order to determine successful solutions that could guide 16 other architects and practitioners in their healthcare projects. We conducted a systematic literature review (SLR) and 17 compared the selected studies based on a characterization schema. The research synthesis results in a knowledge base of 18 software architectures for healthcare CPS, describing their stakeholders, functional and non-functional features, quality 19 attributes architectural views and styles, components, and implementation technologies. This SLR also identifies research 20 gaps, such as the lack of open common platforms, as well as directions for future research.
