In this paper, we propose S/W framework for health care robot based on OSGI middleware. Most healthcare robot developed independently. Therefore most module duplicately developed. However It's not efficient. In this paper we propose S/W framework for healthcare robot that can provide common module for health care robot and can apply heterogeneous robot. By using this S/W framework, we can enhance reusability of s/w module and can provide flexible and efficient development environment.

This paper describes the design and implementation of HNCP bundle in the OSGi framework targeted to the home network system. The developed home network system is composed of a home server and several networked home appliances, and is connected via residential gateway to the external access network. The developed HNCP bundle allows a user to control and monitor home appliances in HNCP domain. We show the feasibility of the implemented HNCP bundle in the OSGi framework.

Recently, many researches focus on Ubiquitous Network which comprised various networks for effective service provision. In particular, OSGi proposed by OSGi Alliance is preferred for core infrastructure to establish Ubiquitous Network as it supports integration and inter-operation among various service environments, and dynamic configuration of services. However, OSGi is limited to be used only within local service framework, since OSGi specification does not have any considerations for inter-operations between internal and external services. Thus, in this paper we propose JARSIO(JAva Remote Service Invocation for OSGi) framework which enables the inter-operations of dynamic internal OSGi services and other external services. The proposed framework is based on the TCP/IP protocol, and provides effective mechanisms for the inter-operations of the services.

In home network environments, the user authentication and authorization associated user's information and usability may be important security issue. The OSGi service platform, a well-known home network gateway already specifies the mechanism of that. The traditional authority method provided OSGi implements simple RBAC(Role Based Access Control) model. This is difficult to support efficient access control. In this paper, we propose the dynamic RBAC model based on OSGi. The proposed method describes the extended framework that manage two roles named as absolute role and relative role, extend existed framework with relative role and propose programming model to enable dynamic access control. Finally, we implement the proposed framework using AspectJ and Java annotation.

OSGi(Open Service Gateway initiative) Alliance는 1999년에 썬 마이크로시스템즈, IBM, 에릭손 등에 의해 구성된 개방형 표준 단체로 지능형 분산 컴포넌트와 원격 관리 될 수 있는 자바 기반의 서비스 플랫폼을 제정 해왔다. OSGi의 핵심은 어플리케이션의 생명 주기를 OSGi 플랫폼 위에서 어플리케이션이나 번들 컴포넌트의 재부팅 없이 실시간으로 설치, 시작, 정지, 업데이트, 제거를 할 수 있도록 지원해 주며, OSGi는 또한 어플리케이션에 포함될 수 있는 형태의 SOA를 구현하고 있다. 본 연구에서는 OSGi가 현재 홈 네트워크에서 많이 사용되고 있는데 그 방향을 자동차 내부의 네트워크 환경에 중점을 두어 실제로 어떤 서비스가 가능한지 시뮬레이션이나 간단한 서비스를 제작하여 알아본다.

OSGi(Open Service Gateway Initiative) offers a unique opportunity for pervasive computing as a potential framework for achieving interoperability between various sensors, home appliances, and networked devices. The OSGi framework supports a remote installation of a bundle, which is a unit that installs and deploys services. However, in order for the bundle in execution to migrate, a specific form of bundle such a mobile agent, is needed one which is able to move through a heterogeneous network. This paper proposes a method that can manage bundles like these dynamic agents, in order to ensure the mobility of entities in multiple OSGi framework environments. For our purposes, we have designed the mobile agent management system for managing the lifecycle and mobility of agents in the OSGi framework. The mobile agent management system we are proposing implements a bundle form which can perform in an OSGi framework as well as manage autonomous mobile services. As a result, mobility in a pervasive environment will be supported more efficiently.

The OSGi framework is a java-based service platform that can be remotely managed, providing an application life cycle management model, a service registry and an execution environment. Based on the framework, various OSGi layers, APIs, and services have been defined. A bundle is an application that can be executed in the OSGi framework, deployed through a bundle repository. Usually, bundles in the repository are accessible via a designated web page. Unfortunately, the current bundle repositories do not provide any kind of group access services and dynamic bundle installation and deployment. In this paper, we describe a WebDAV-Based OSGi bundle repository named WOBR, which supports effective group-based accesses. WOBR is composed of a WOBR bundle repository, a management bundle and an access bundle that interact with the bundle repository. The management bundle is for configuration of the WOBR bundle repository, managing group access facility to the repository. The access bundle provides access to the repository and search mechanism for the bundles. Additionally, it provides the life cycle management of the installed bundles on the local environment.

In this paper, we implemented a FIPA-OS multi-agent framework bundle in OSGi Service Platform. FIPA-OS is an open agent platform for constructing FIPA compliant agent using mandatory components that required by all FIPA-OS agents to execution and optional components that FIPA-OS agent car optionally use. The platform supports communication between multiple agents and communication language which conforms to the FIPA standards. FIPA-OS framework bundle is composed of DE(Directory Facilitator), AMS(Agent Management System), ACC(Agent Communication Channel) and MTS(Message Transport System) bundle. These bundles installed in the OSGi service platform and their life cycle can be managed by the framework.

In this paper, we implemented the FIPA-OS framework bundle and service agent bundle over the OSGi service platform in home-sewer platform. The FIPA-OS is the first open source implementation of the FIPA standards and is a component-based toolkit implemented in Java. The FIPA-OS bundle is composed of two bundles. One is the communication bundle such as RMI, IIOP, HTTP and ACC. Another is the agent loader bundle. Experiments are conducted on the service agent communication and loading by the agent loader bundle, and the proposed bundles are successfully installed, stopped, and uninstalled over the OSGi service platform.

본 논문에서는 OSGi서비스 프레임워크 환경에서 서비스의 접근 통제 기법을 구현할 수 있는 정형화된 보안 모델을 제시하고 있다. OSSEM(OSGi Service Security Extension Model)이라고 하는 이 보안 모델은 위임, 허가, 거부의 3가지 권한 엔트리를 정의하여 동적으로 설치되는 번들에서 독립적인 보안 정책의 설정을 지원하며, 다른 번들의 정책과 결합될 때 안전한 서비스의 수행을 보장한다. 이 모델은 유연성있는 보안 정책의 설정의 가능하고 OSGi 서비스 프레임워크 환경에서 기존의 Java 2 보안 아키텍처와 쉽게 통합이 가능하므로 번들과 서비스에 대한 접근 통제 뿐만 아니라 OSG 내부 자원의 접관 통제 방안으로도 확장할 수 있다.
