    Publicado em December 6th, 2012Publications

    The paper “Smart Cities Software Architectures: A Surveyauthored by Welington Manoel da Silva, Gustavo Henrique Rodrigues Pinto Tomas, Kelvin Lopes Dias, Ricardo Alexandre Afonso, Alexandre Alvaro and Vinicius Cardoso Garcia has been accepted for publication in the Software Architecture: Theory, Technology, and Applications (SA-TTA) Technical Track at the 28th Symposium On Applied Computing (SAC’2013).

    The conference will be held in March 18 - 22, 2013 at Institute of Engineering of the Polytechnic Institute of Coimbra (ISEC-IPC), Coimbra, Portugal.

    This activity is part of the project “Social Machines and Research Team - SMaRT” and is one of the results of the MSc research being done by Welington Manoel da Silva and Gustavo Henrique Rodrigues Pinto Tomas and PhD research being done by Ricardo Alexandre Afonso.

    A brief overview of the paper is given next

    The smart cities concept arises from the need to manage, automate, optimize and explore all aspects of a city that could be improved. For this purpose it is necessary to build a robust architecture that satisfies a minimal number of requirements such as distributed sensing, integrated management and flexibility.

    Several architectures have been proposed with different goals, but none of them met satisfactorily the needs that permeate smart cities.

    In this work various architectures are discussed, highlighting the main requirements that they aim to fulfill. Furthermore, based on different architectures with the most varied purposes, a set of requirements for the implementation of a smart city is presented and discussed.

  • INES at Seventh International Conference on Software Engineering Advances (ICSEA 2012) - Part II

    Publicado em September 12th, 2012Publications

    INES researchers had two papers accepted for publication in the 7th International Conference on Software Engineering Advances (ICSEA) 2012:

    1) “Evaluating performance of distributed systems with MapReduce and application traffic analysis” authored by Thiago Vieira, Paulo Fernando Soares, Marco Machado, Rodrigo Assad and Vinicius Garcia; and,

    2) “A Systematic Mapping Study on Domain-Specific Languages” authored by Leandro Nascimento, Daniel Viana, Paulo Silveira Neto, Dhiego Martins, Vinicius Garcia and Silvio Meira.

    Both papers are part of the research activities being performed in the project “Social Machines and Research Team - SMaRT”. We are gathering other members in this research group and creating a new one with a more general proposal, called Advanced Software Systems Engineering and Research Technologies (ASSERT): www.assertlab.com

    The conference will be held in November 18-23, 2012 - Lisbon, Portugal.

    A brief overview of both papers is given next:

    1) Abstract. Test, monitoring and evaluation of distributed systems at runtime is a difficult effort, due the dynamicity of the environment, the large amount of data exchanged between the nodes and the difficulty of reproduce an error for debugging. Application traffic analysis is a method to evaluate distributed systems, but the capacity of analyze large amount of data is a challenge. This paper proposes and evaluates the use of MapReduce programming model to deep packet inspection the application traffic of distributed systems, evaluating the effectiveness and the processing capacity of the MapReduce programming model for deep packet inspection of a JXTA distributed storage application, in order to measure performance indicators.

    2) Abstract. Domain-Specific Languages (DSLs) offer substantial gains in expressiveness and ease of use compared with general purpose languages. This way, DSLs have gained significant attention in industry and academy, as can be seen by the increased number of related publications in key conferences and journals. This paper aims to provide a broad view of the DSL research field by performing a Systematic Mapping Study. Adopting a detailed search strategy, 4450 studies were initially identified, and, after filtering, 1440 primary studies were selected and categorized using a particular classification scheme. So, this work presents the most popular application domains where DSLs have been applied, identifies different tools for handling DSLs, including language workbenches, and enumerates several techniques, methods and/or processes for dealing with DSLs.

    Publicado em September 12th, 2012Publications

    The paper “Measuring performance of distributed applications through MapReduce and network traffic analysis” authored by Thiago Pereira de Brito Vieira, Paulo Fernando Almeida Soares, Marco Andre Santos Machado, Rodrigo Elia Assad and Vinicius Cardoso Garcia has been accepted for publication in the 18th IEEE International Conference on Parallel and Distributed Systems (ICPADS) 2012 in Singapore.

    The conference will be held in december 17 - 19, 2012 at Nanyang Executive Centre, Nanyang Technological University, 60 Nanyang View, Singapore.

    This activity is part of the project “Social Machines and Research Team - SMaRT” and is one of the results of the MSc research being done by Thiago Vieira.

    This paper proposes the use of MapReduce programming model to deep packet inspection of distributed systems network traffic, performing a initial evaluation of effectiveness and processing capacity of MapReduce for deep packet inspection, and also evaluating the performance indicators that can be extracted to evaluate a distributed application.
