Recently, there has been increasingly demand for connecting a embedded device to the Internet. Jini technology is interested in automatically composing a distributed network with devices But, there are some problems that the device needs high hardware requirements to adopt Jini technology for supporting Jini-enabled services. In this paper, we focused on design and implementation of surrogate system that supports non-Java devices in Jini networks. This system and protocol are implemented in Java language. The surrogate system delegates Discovery and Join processing to support a Jini service in connected networks. A Jini client can use service of the device through the surrogate system. We tested a Jini sample program to verify the implemented surrogate system. In the test result, we showed that the Jini client can use functionalities and operations of the non-Java device through the surrogate system.

Jini is a middle ware supposed in Sun Microsystems. The goal of lil is the establishment of dynamic distributed system, which can share information and control of other Jini technology-enabled services or devices in the same Jini system. Jini is one of the best middleware together UPnP and HAVi. Hone network security, soch as privacy protection, crime prevention, and etc, is very important. So Jini 2.0 adds security mechanism in 11. 2003. This paper describes the analysis of Jini 2.0 security mechanism, and home network security.

Recently, the Progress of computer environment has been changed from integration to distribution. This rapid progress makes several novel fields like Jini & Mobile Agent systems. Although these provided the new technology. but not used commonly. Because they have some problems. That is Jini has a problem of giving a heavy load on the service, and the Mobile Agent technology has not supported dynamically routing. This paper will Provide a design of Mobile Agent that routed dynamically, and propose a system which offers a service to client with giving low to the service.

We investigate the middleware technology which will take a major role of extending the usage of home networking. UPnP and Jini belong to the most important technologies among them. In this paper, we suggest the interoperability between UPnP and Jini. We describe the design and implementation of UPmp-to-Jini service which makes it possible for a Jini client to utilize a UPnP device.

Jini architecture's Network Plug and Work provides simple and flexible network environment for distributed applications. Through the Jini technology, facilities for dynamically registering and locating mobile agent services can be easily supported, as well as the services useful for activities of mobile agents can be dynamically supported. In this paper, we describe a Jini-based mobile agent system named JMoblet, which provides the basic functions of a mobile agent system such as creation, control, transfer, location and communication among agents. To increase the reliability of the system, it also provides exception handling and persistence of the mobile agent systems for reliability.

The home network system guarantees families a safe, economical, socially integrated and healthy life by using information appliances. And it provides a family with domestic safety, control of instruments, controllable energy and health monitoring by connecting to home appliances. This study designs the broadband PLC home controller using broadband PLC(Power Line Communication) technology which can save much cost at a network infrastructure by using the existing power line at home. The broadband PLC home controller consists of the broadband PLC module, the embedded main controller module and I/O module. The broadband PLC home controller can control various domestic appliances such as an auto door-lock, a boiler, an oven, etc., because it has various I/O specifications. In this study, selected home network middleware for the broadband PLC home controller is Jini surrogate using Jini technology designed by means of access to easily a home network system without a limitation of the devices. And a client application program is supported java servlet program to manage and monitor the broadband PLC home controller via web browser of a PC or a PDA, etc. Finally, for an application, we implemented and tested a home security system using one broadband PLC home controller.

Jini is a promising HomeNetworking middleware of computing environment based on Java Technology. To support Homenetwork service based on Jini, Jini device requires a successive operation and complicated management. In this paper, our service management system is a service provider component and lookup service component including automation module. Our automatin module privide searching and setting function of a library, runtime environment and class file system cinfiguration information for Jini service. Our system can be accomplished by automation of runtime environment, simplification of service management structure, visualization of service execution.

In this paper, we consider issues related to the autonomous management of a server cluster Server clustering technique is widely used for high available Internet servers such as a web server, because it provides very scalable and reliable service. However, it is very burden-some to manage the cluster system. For instance, installation or configuration of a new node requires skilled administrators. Also, when a node is failed, it should be recognized and recovered by a human. The management complexity gets higher while increasing the number of machines for higher throughput. Here, we are going to alleviate the management complexity by building an autonomous cluster server with Jini $_{TM}$ technology from Sun Microsystems.

Network infrastructure has spread to an unprecedented extent and is used in various computing devices, such as smart appliances, smart phones, and embedded devices with sensors, which have all been appearing in the computing environment. To accommodate this trend, for a more intelligent service environment, the service platform needs to have abilities that facilitate the operation between services, dynamically share distributed computing resources, and manage appropriate contextual information. We have simulated a service platform to provide intelligent services using contextual information after having implemented the context management service. The context management service gathers raw contextual information from sensors and stores these in the context database. For a consistent basis of contextual information, time and location are used as the key values of the contextual information. The context management service also performs normalization to provide computable contextual information to context-aware applications. In this paper, a service platform based on Jini technology is proposed for constructing an interoperable, dynamic, and . intelligent service environment using contextual information.
