  • A Process Engineering Method based on a Process Domain Model and Patterns
    2017
    Co-Authors: Charlotte Hug, D.b Rieu
    Abstract:

    There are many different process meta-models that offer different viewpoints of a same process: activity oriented, product oriented, decision oriented, context oriented and strategy oriented. However, the complementarity between their concepts is not explicit and there is no consensus about the concepts themselves. This problem leads to inadequate process meta-models with organization needs, so the instantiated models do not correspond to the specific demands and constraints of the organizations or projects. However,, Method engineers should be able to build process meta-models according to the specific organization needs. We propose a Method to build unified, fitted and multi-viewpoints process meta-models. The process Engineering Method is based on a process domain model and on patterns.

  • Applying a web Engineering Method to design web services
    Lecture Notes in Computer Science, 2005
    Co-Authors: Marta Ruiz, Pedro Valderas, Vicente Pelechano
    Abstract:

    Probably one of the most difficult tasks in the development of a Service Oriented Architecture (SOA) is how to obtain well designed Web Services. Some Web Engineering Methods provide support to introduce Web services in the software development process but do not give support to the systematic design and implementation of them. In this work, we present an extension of a Web Engineering Method (called OOWS) to provide a Methodological guide for designing Web Services. This allows identifying and designing the operations and arguments of Web Services following a model-driven approach, taking the OOWS conceptual models as a source. To document our approach, we apply our ideas to the design of the Amazon Web Service and compare our proposal with the solution provided by Amazon.

  • An adaptive type-2 fuzzy traffic Engineering Method for video surveillance systems over software defined networks
    Multimedia Tools and Applications, 2017
    Co-Authors: Reza Mohammadi, Reza Javidan
    Abstract:

    Software Defined Network (SDN) is a new network technology which allows network providers to afford predefined Quality of Service (QoS) for video streaming applications. Network administrators can develop desired traffic Engineering techniques over SDN and support Quality of Experience (QoE) and QoS for their customers. One of the most important issues in traffic Engineering is to find favorable links for routing between source and destination. The fitness of each link in the network depends on the end users QoE and the applications they are used. In this paper to achieve optimal routes, the fitness of each link is determined by type-2 fuzzy sets. Then, an adaptive traffic Engineering Method is proposed to find the best routes between source cameras and monitoring center in a video surveillance system. The proposed Method is based on Constraint Shortest Path (CSP) problem and calculates minimum cost path which satisfies delay constraint. Due to NP-completeness of the CSP problems, LARAC algorithm is used to solve it. To the best of our knowledge, this is the first proposed traffic Engineering technique which is based on type-2 fuzzy set for video streaming applications over SDN. The contribution of the proposed Method regarding to the related works, is to apply type-2 and type-1 fuzzy logic for calculating the costs of network links based on QoE for providing QoS in a video surveillance system. In addition, this paper models the provisioning of QoS in a real scenario and emulates them in a network emulator. Many comparisons carried out between the proposed Method and other well-known Methods to show the effectiveness of the proposed Method in terms of packet loss, delay and PSNR.

  • A new adaptive traffic Engineering Method for telesurgery using ACO algorithm over Software Defined Networks
    European Research in Telemedicine La Recherche Européenne en Télémédecine, 2017
    Co-Authors: Mohammad Reza Parsaei, Reza Mohammadi, Reza Javidan
    Abstract:

    Summary Introduction In the past decades, telemedicine has attracted much attention due to its usefulness for delivering medical services from remote location. One of the most important parts of telemedicine is telesurgery, in which a surgeon performs surgery on the patient from remote location by using telecommunication networks. Due to the surgeon needs to watch the patient side transmitted video with high quality; it is necessary to provide fast and suitable communication path between the surgeon and patient. Emerging Software Defined Network (SDN) as a new network paradigm facilitated Quality of Service (QoS) provisioning in many applications. Decoupling data plane from control plane in SDN, helps to manage based on end users requirements. This paper proposes a new heuristic traffic Engineering Method for telesurgery application using Ant Colony Optimization (ACO) algorithm. Patients and Methods This paper models QoS provisioning in Telesurgery as a Constraint Shortest Path (CSP) linear programming problem. Moreover, due to NP-completeness of CSP problem, this paper proposes a solver Method using ACO algorithm. To the best of our knowledge, this is the first paper which investigates QoS provisioning for telesurgery in SDN. Results Results of performance evaluation showed that the proposed Method is better than baseline Method. The proposed Method improves all three important QoS parameters, average End-to-End delay, packet loss ratio and PSNR with values of 56.3%, 50.5% and 1.33, respectively. Discussion providing QoS in telesurgery applications is one of the most challenging issues. By leveraging the capability of SDN, we can develop appropriate mechanisms to guarantee QoS requirements in critical applications such as Telesurgery. Conclusion Using SDN together with optimization models such as CSP for providing QoS in Telesurgery can improve the quality of the received video in an operation room. This mechanism causes increment in the performance of Telesurgery.
