In this paper, we developed mobile robot platform called Ecobot for the application system of friendly environment smart home appliance. Ecobot fulfills the purposes of monitoring of the healthy environment and guidance in the application system of friendly smart environment home appliance, home network formed by Zigbee network. For the healthy environment, the system contains monitoring sensor. Moreover, it continuously keeps the healthy environment by controlling the smart home appliances linkng with Zigbee network. And also using the URG-04LX laser distance sensor, it monitors indoor environment through autonomous moving and collision avoidance.

In this paper, we propose a method for the efficient power use in power outage. The cost is high and conversion into the other function is difficult since the terminal used in conventional home network system has a dedicated function. This method is based on home network system employed with photovoltaic system. Throughout the modularization of the terminal, the variable function and cost reduction can be achieved. Additionally the unit cost can be reduced by using the power line communication. The prototype of light-control terminal has been implemented. The experimental results with the terminal show the performance of light-control system and the possibility of the commercialization can be achieved.

In recent years, many researches in Home Networking are being progressed actively. Most of techniques for Home Networking are based on wired but the technique for wireless connection is also needed. This paper focuses on wireless connection in Home Networking. Of many of wireless technologies, such as Wireless LAN, Bluetooth, or HomeRF, we especially propose to apply the new technique called Wireless Sensor Network. We present hardware and protocol stack design consideration for wireless sensor node and wireless sensor network, and then we present how to apply wireless sensor network to Home Networking and how to constitute Wireless Home-Networking with a variety of sensor nodes. Finally, we introduce the wireless sensor node system designed by us and conclude this paper.

In this paper, a home network message specification and systems based on the Power Line Communication(PLC) are proposed. As a case study, the home network message specification and systems for the white goods are proposed. It is designed for the various home appliances from the lightning to the white goods using power line communication based on Internet protocol. The proposed home network system is composed of the home network message specification with browsing S/W and embedded H/W design based on the power line communication.

Home network providers have many worries about providing home network services with an expandable, reliable, flexible and low-cost structure according to the expanding market environment. The existing client-server system has various problems such as complexity and high costs in providing home network services. In this paper we propose the P2P-SIP structure. P2P communication terminal supporting access of distributed resources provides functions which the existing SIP-based network devices have. Because diverse terminals in a home network access through networks, also, partitioning network domains with home gateways to manage, and applying the network-based PMIPv6(Proxy Mobile IPv6) technology considering mobility of terminals would help to have a more efficient home network structure. Especially, the proposed P2P-SIP structure proves itself as a very efficient structure to have an outstanding expandability among different home networks in a region, and to reduce maintenance costs.

As the Internet of Thing(IoT) technology recently has become a big issue, many researches have been carried out to link the Internet of things with the home network system. Various home network systems are being implemented to connect many devices used in the home with the Internet and to control and operate the devices using a smart phone. However, existing protocols that operate on the Internet are not suitable for a limited environment such as low power, low capacity, and low performance. Therefore, the Internet Engineering Task Force (IETF) Working Group proposed the CoAP/6LoWPAN technology as a suitable protocol for internetworking IoT devices with the Internet in a limited environment and adopting it as a standard. In this paper, a smart home network system is implemented to control and operate various IoT devices in a home using CoAP/6LoWPAN in mobile environment. The performance of HTTP and CoAP such as data transmission time, data transmission rate is analyzed.

A home network system is made up of subject of cyber attack from a variety factors of threatening, but also have security weakness in cases of hacking, vicious code, worm virus, DoS attack, tapping of communication network, and more. So, the necessity for a security protocol to protect user asset and personal information within a home network is gradually increasing. Thus, this paper designs and suggests a home network security protocol using user authentication and approach-control technology to prevent the threat by unauthorized users towards personal information and user asset in advance by providing the gradual authority to corresponding devices based on authorized information, after authorizing the users with a Public Key Certificate.

Home networking and Internet control technologies must satisfy three requirements with a view to being applied to home for raising the qualify of human life. Firstly, the cost of adding home networking ability to the traditional appliance must be minimized. Secondly, the mutual accessibility between home network and Internet must be guaranteed in the various Internet service environment of home. Finally, communication must be possible between the home network and the Internet that use different communications protocols. This paper proposes the ARCS (Appliance Remote Control System) that controls appliances based on LnCP (Living network Control Protocol) via the Internet. LnCP is the most cost-effective network and control protocol for home network. ARCS guarantees the accessibility from the Internet to home network and provides users with the virtual interface designed for controlling appliances using the Internet application program. In addition, this paper proposes AICS (Appliance Internet Control Specification). AICS, is based on LnCP, defines the message structure and control commands for the Internet control communication. ARCS and home gateway are developed to meet AICS.
