As various kinds of embedded systems (or devices) become widely available, research on home network middleware which can access and control embedded home appliances are actively being progressed. However, there is a significant problem in applying the home network technology to embedded systems because of their limited storage space and low computing power. In this paper, we present a lightweight middleware for home network on embedded systems. Also, we propose a mechanism for mobility management which adopts the anycast technology.

Government is supporting development of home networking. But, this new system is much expensive to introduce in the home. And limit for establishment is so many in the home. Therefore, in this paper, We escape from monotonic control of Home Automation and draw a plan Intelligent Home Automation to be developed. We reflect Home Network to the foundation and propose Home Automation on Ubiquitous Sensor Network, We Design of Ubiquitous Home Automation System for 35-Pyung Apartment Based on USN Environment. This becomes the Home Automatic Behavior System which is executed to the automatic to be improved.

There are increasing interests on smart home systems. However, most of the existing works focus on the functionality itself. In this paper, we propose an extensible smart home system based on low power networking such as CoAP, 6LoWPAN, and Zigbee. The proposed home IoT system consists of Home APP, Home Server, Home Broker, and Power Devices. Each component of the system is connected by the low-power network technologies aforementioned. As the end device, Power Device senses the current consumption of the attached appliance and controls the power to it. Power Device reports the sensing data to Home Server via Home Broker. The Home Broker enhances the scalability of the system. Home Broker extends the service area and the user's services, and it manages the connection of the underlying devices and processes, and transmits data to Home Server from Power Devices. Through the experimental evaluation, we show that the proposed system achieves the design goals such as extensibility and low power networking.

On-going convergence between broadcasting and communication is currently bringing in lots of drastic changes to multimedia services to the home. The FTTH-based home networks will be the interface among the digital home appliances for broadcast digital contents as weil as for broadband data connection. In this paper, we discuss several design issues for home gateway architecture that effectively distributes realtime broadcasting contents (from either the headend in the access network or the satellite/terrestrial broadcasts) to heterogeneous devices in the home network.

Since different kinds of home network technologies coexist, seamless connections between different kinds of network protocols are essential for home computing environments. Several kinds of home network middleware have been developed and OSGi(Open Service Gateway Initiative) was initiated mainly for interoperability support with service distribution between various middleware environments. Framework, OSGi service platform, has weaknesses of passive service bundle management, user management and device management. Therefore, this paper resolves passive management parts which are critical weaknesses of OSGi Specification Version 3 and proposes SBM (Service Bundle Manager) to effiently manage various service bundles. Additionally, we verify practical effects of SBM through experiments.

It is rapidly expanding to provide Home Digital Service based on the Home Network System in intelligent apartment. Fortunately, Korea has one of the highest rates of Internet penetration and access in the world. Construction companies used the Home Network system as a strategy of differentiation and it is available to the customers to raise their asset value. Besides, the government has a positive response to accept the new movements to make the digital environment with 'u-Korea (Ubiquitous Korea)' as the slogan. However, the level of providing Home Digital Service is actually at the beginning. The develop the home network industry more effectively, the related industries' cooperation is essential. The purpose of this study is to propose a providing model of Home Network System for the construction company and to make a method to response the fast change of technology development and customer's request at the point of construction companies' view.

A home network provides users with a variety of information services. The kind and quality of the services can be substantially enhanced by utilizing a variety of data from sensors. However, home networks currently limit their potential by focusing on providing multimedia services rather than services utilizing sensor data. Outdoor electronics are frequently made in a form that emphasizes only certain limited functions in contrast to home appliances. Thus, sensors with one or two functions rather than many can be used in outdoor systems and their use will be more economical than using sensor nodes indoors with more complex home appliances. In this study, we chose to work with motion sensors as they have many potential uses, and we selected a parking lot control system with to use the motion sensors. This parking lot control system was implemented and applied as part of a home network. For this purpose, we defined and implemented a protocol to manage the network in a ubiquitous sensor network environment for the wireless home network in this study. Although a network management system in a Ubiquitous Sensor Network (USN) related to this study is being advanced for other projects, the protocol interface and message system have not yet been clearly defined for use in a general purpose network or in an extension into heterogeneous kinds of networks, communication support, etc. Therefore, USN network management should be conducted for management of faults, composition, power, and applications. To verify the performance of the protocol interface designed in this study, we designed and implemented the necessary units (sensor nodes, sensor gateway, and server) for each network section and, with them, proved the validity of this study.

As smart home network services such as home CCTV, outdoor control of home appliances, home security and disaster prevention services become popular, there appear various affiliated products including smart home gateway and smart speaker. Since those services are generally developed on the vendors' individual hardware and software platforms, it is not much expected for them to interwork well among different architecture and communication methods. In this paper, we propose a new home network service system running on an open source platform to address such issues. We implemented a home network system using OpenWRT-based wireless router(or access point) and Zigbee communication technology. In the proposed system, a wireless router replaces a commercial home gateway and small control units implemented with Arduino control electronic devices and sensors in home. Several service scenarios are also implemented to verify the operability of the proposed system.

The purpose of this study was to analyze the research trends and co-author networks of academic articles published in the Journal of the Korean Home Economics Association from 2010 to 2022. The network analysis was conducted using Excel and NetMiner 4.4, and the results were as follows. First, the number of published articles has been maintained at around 40 per year since 2019. By field, most articles were published in the field of child studies and family studies, followed by consumer studies, home management, clothing studies, home economics education, food and nutrition, and housing. The research methods were primarily quantitative (71.61%). Second, the most common keywords in the titles of the published articles were "influence" and "relationship", with "influence", "consumer", "mediating effect", "parent", and "control" identified as influential keywords. Third, the published articles were categorized into nine topics based on subject matter, while the number of topic types varied by year. Fourth, the total number of authors of the 627 articles was 712, with 1.92 authors per article, as well as the number of authors who published two or fewer articles accounted for 85.5% of the total. By institution, Yonsei University had the highest number of authors and the highest number of published articles, while Korea National Open University played a leading role in the network of co-authors by institution. This study is significant in providing basic data for the future development of the Korean Home Economics Association and the field of home economics.
