The Sensor Network enables many distributed systems to be unmanned and automated by using of diverse sensors as well as wireless communication technologies. One of major enabling technologies for the sensor network is the USN middleware which plays the role of collecting and analyzing of measurements of sensors and controlling of the environments. The paper deals with the fungus cultivating environment based on Sensor Networks. Especially, we focus on the design of USN middleware for the embedded system, and explain how to design software architecture in terms of architectural patterns. In this design process, the improvement of methodology for pattern-oriented architecture design is proposed and the quality attributes for the architecture design is newly classified and suggested for the reference of software architecture design.

USN(Ubiquitous Sensor Network) environment that provides the service measured from sensors in real-time the information is delivered to application service. However, domestic service, application service provider environment between providers and users, most of the research are on the service platform architecture, and process the information detected by sensors between the providers of standard services platform architecture, which is a very weak level. In this paper, we proposed new service architecture though analysis of the OGC SWE(Sensor Web Enablement) with standards and research analysis of domestic standards. And we designed and implemented to each component of provider side.

It has been constantly demanding for effective way to improve software development productivity and automation. In this paper, we did research to configure the component assets to reuse design information from the design phase domains based on the DMI. It is necessary abstracted information architecture of an independent platform development environment to reuse design information on the design stage. Also, It should be based on a well-designed to support the design architecture of the application domain. Therefore, in this paper, I want to use the DMI architecture that can be represented by formal level of architectural design information platform and application domain area. It is able to decomposition architecture asset with the part design information from the design phase composition or a high level of abstraction on DMI. Therefore, the metadata structure of the asset architecture will support a structure which can reuse the structure-based design of the domain areas.

Component-Based Development(CBD) leverages software reusability and diminishes development costs. Various works about component models, such as EJB, COM, and CCM are in progress to support CBD. However, current component models hardly support flexible assembly of pre-built components. To cope with this problem, architecture for component assembly must be defined in the abstract level and the gap between system architecture and its implementation should be diminished in the implementation level. This paper proposes a method for architecture-based design and implementation of component assembly. Architecture is described by the ADL, and the tool, COBALT Assembler, is introduced to support the proposed design and implementation phase of component assembly.

Due to the software is getting complex and large, software architecture design is issued for success of project. In the design phase, selection of the suitable architectural approach is very important. In this thesis, we identify the architectural approach alternatives in the design phase. And the evaluation method to choose architectural approaches and the architecture design methodology integrated with that evaluation method are proposed In the proposed architecture evaluation method and the architecture design methodolody, we intend to raise reliability, completeness of design and reduce development costs.

Software architecture is increasingly being viewed as a key design in developing complex software systems, which largely affects the achievement of quality attributes. During the architecture-based software development, therefore, architectural transformation is needed to achieve quality attributes. Due to the variety of design alternatives and the poor predictability of the effects of the transformation, however, it is not easy to apply architectural transformation. Therefore, the method is needed to support architectural transformation through systematically analyzing the effects of applying various design alternatives to the architecture. This paper proposes an approach to support software architecture transformation. Based on architectural design decisions and the constraints on them included in the architecture, our approach defines a decision constraint graph representing the dependencies among architectural design decisions. Through using the decision constraint graph, architectural transformation can be systematically performed by understanding the effects of applying a transformation. While this work supports more understanding of applying architectural transformation, it also helps reconstruct a software architecture to improve the quality of the software.

소프트웨어 아키텍처는 소프트웨어 컴퍼넌트와 이들 컴퍼넌트들 간의 상호 관계를 나타내는 시스템의 전체적인 구조이다. 이때 완성된 시스템이 품질에 대한 요구를 만족시키는 시스템인지의 여부를 결정하는 아키텍처의 평가가 매우 중요하다. 그러나 평가 과정에서 아키텍처에 대한 부적절하거나 모호한 표현으로 인해 광범위한 응용에서는 않은 제약이 따른다. 그러므로 본 논문에서는 소프트웨어 아키텍처를 평가하기 위해 준비하고, 실행하고, 완료하는 세 가지 단계 제시한다. 이들 단계를 수행함에 따라 품질 속성의 획득에 많은 영향을 주는 아키텍처의 설계 결정을 중심으로 체계적인 아키텍처 평가가 이루어질 수 있다.

The purpose of this paper is to design a system model which is needed for integrating the secure role-based access control model into web-based application systems. For this purpose, firstly, the specific system architecture model using a user-pull method is presented. This model can be used as a design paradigm. Secondly, the practical system working model is proposed. which specifies the mechanism that performs role-based access control in the environment of web-based application systems. Finally, the comparison and analysis is shown in which the merits with the proposed system model is presented.
