  • We introduce new type of networked robot, Ubiquitous Robotic Companion (URC), embedded with ATLAS Service-oriented architecture for enhancing the space sensing capability. URC is a network-based robotic system developed by ETRI. For years of experience in deploying service with ATLAS sensor platform for elder and people with special needs in smart houses, we need networked robots to assist elder people in their successful daily living. Recently, pervasive computing technologies reveals possibilities of networked robots in smart spaces, consist of sensors, actuators and smart devices can collaborate with the other networked robot as a mobile sensing platform, a complex and sophisticated actuator and a human interface. This paper provides our experience in designing and implementing system architecture to integrate URC robots in pervasive computing environments using the University of Florida's ATLAS service-oriented architecture. In this paper, we focus on the integrated framework architecture of URC embedded with ATLAS platform. We show how the integrated URC system is enabled to provide better services which enhance the space sensing of URC in the smart space by applying service-oriented architecture characterized as flexibility in adding or deleting service components of Ubiquitous Robotic Companion.

  • In this article we review the metaphor of service-oriented architecture for enterprise computing. In typical definitions service-oriented architecture appears as a single message and a consistent roadmap for building flexible software system landscapes. But it is not. Different communities have elaborated different SOA (service-oriented architecture) concepts to address different problem areas, i.e., enterprise application integration, business-to-business, business process management, and software productizing. If software architects and software managers are aware of these strands of SOA when talking about SOA in their projects they can avoid misunderstandings and detours better. This article contributes a clarification of the different strands of SOA concepts and technologies and their mutual dependencies and identifies particular SOA concepts as instances of more general software engineering principles.

  • In order for end-users in home networks to receive opportunities for useful services that go beyond legacy Internet Protocol TV (IPTV) services, this paper proposes a service platform that resides on the residential gateway (RG) for interworking between the home network and IPTV. This proposed service platform is called the home-oriented IPTV service platform (HISP) on the RG (HISP-RG). The proposed HISP-RG provides open architecture and functionalities to enable 3rd party IPTV service providers to locally and directly deliver home-oriented IPTV services to end-users in home networks. The HISP-RG can be an "add-on" and not a "built-in" solution for the existing standard RG. This paper introduces several home-oriented IPTV services that can be executed and delivered locally through the HISP-RG. Then, the open architecture and functionalities of the HISP-RG are defined and their requirements are specified. Finally, use cases of the HISP-RG for home-oriented IPTV services are presented.

  • Service Oriented Architecture(SOA) is a flexible structure which does not affect other services even when a specific service is changed. It provides the platform with neutral interfaces independent of any others, where services are loosely coupled in a standard way. While ESB (Enterprise Service Bus) is a key technology for service-oriented architecture, few research and development for ESB has been done. In this paper, we designed and implemented the key components of ESB such as mediation service, message oriented middleware service, operation service, monitoring service, application connection service, and database connection service. The performance evaluation was done by measuring the message processing time for the number of messages with various sizes.

  • Nowadays, as the importance of service-oriented architecture software is recognized, the market of service-oriented software is getting bigger. In response to this, the requirements of high reliability and quality about service-oriented architecture software is getting increased. In this research, we clearly suggested the evaluation method by giving a specific evaluation example to evaluate the reliability qualify of service-oriented architecture software. It is expected to raise the objectivity and the utilization by inducing the reliability qualify improvement from this research.

  • Service Oriented Architecture (SOA), which supports various features such as interoperability and reusability of IT resources, comes into the spotlight as an effective approach for adapting new business environmental changes. SOA, however, has some problems including the high realization complexity and low Return on Investment (ROI). To solve these problems, Web Oriented Architecture (WOA) has gained attention. However, it also has some drawbacks about security concerns and unstable message transmissions. In this paper, we design a novel integrated architecture that classifies services into inside and outside ones and applies SOA for the former and WOA for the latter, respectively. By converging the advantages of SOA and WOA simultaneously, the proposed architecture becomes more simple and service-oriented, and can satisfy diverse requirements of customers. The usefulness evaluation of the proposed architecture is conducted through the Analytic Hierarchy Process (AHP) scheme.

  • Service Oriented Architecture (SOA) is rapidly emerging as the efficient approach in contemporary complex, heterogeneous computing environments. SOA increases the adaptability by loose coupling and its main feature is that three elements such as service provider, service requester and service registry are connected with each other systematically. To design the service-oriented system efficiently, a metric to measure the coupling between services accurately is needed. In this paper, we propose four coupling metrics for SOA based softwares. First, we suggest a coupling metric for service-oriented systems by modifying an established coupling metric of object-oriented systems. Then we suggest another coupling metric which includes indirect coupling between services. We also suggest two relative coupling metrics to measure coupling between subsystems. We investigate the theoretical soundness of the proposed metrics by the axioms of Briand et al. Finally, we apply the presented metrics to an industrial-scale case study.

  • Service Oriented Architecture(SOA) is an enterprise-scale IT architecture for linking software resources available on the network. SOA is believed to become the future enterprise solution that promises the agility and flexibility by integrating business processes through composition of the software services across enterprises. The first step for SOA construction is to identify the services. In this paper, we present a process-based service identification methodology for SOA through a case study of an IT company. Our methodology is composed of three steps: Processes (business & technical processes) analysis and systems analysis, Service candidates selection, and Service evaluation and construction planning. This framework would be practical and could be accepted to other organizations as it has been developed through the real case.

  • Recently, Service-Oriented Architecture(SOA) is on the rise to reduce the complexity of IT infrastructure, minimize cost for maintaining it and maximize the productivity and flexibility in business. SOA increases the adaptability by loosely coupling and it's main feature is that three elements such as service provider, service requester and service registry are connected with each other systematically. These make difficult to adopt traditional development methodologies to implement SOA. In this paper, we suggest a service-oriented development process with regard to the aspect of service provider and service requester. The process consists of six phases and each phase sets up with guidelines and artifacts. It can choose the process type along with the goal in Development Planning.
