This paper proposes the new concept & design method and implementation of LonWorks network system for remote monitoring & lighting dimming control and telemetry using Web network. The Experimental LonWorks network system for telemetry & remote monitoring and control are designed and fabricated. As a result, it is verified that LonWorks is open, inteoperable, reliable network system from the experimental results, especially, it seamlessly links the data and control networks, allowing the IP(internet) network to be treated as an extension of the LonWorks networks, and vice versa.

Devices compliant to the Universal Plug and Play (UPnP) Audio Video (A/V) specifications can easily establish multimedia home networks through zero or auto configuration. Despite the existing UPnP certification process many issues concerning interoperability still arise. Capabilities may not be fully implemented or there may be codec issues. Therefore, a means to check and verity interoperability prior to product purchasing or usage is necessary. In this paper, an implementation of a portable control point is proposed to store and manage UPnP device capability information. The portable control point can be used to find UPnP A/V compliant devices that are most compatible.

UPnP(Universal Plug and Play) is a middleware of DLNA (Digital Living Network Alliance) services a home network. UPnP supports the connections between each other devices in networks and also provides service discovery and advertisement with SSDP(Simple Service Discovery Protocol), which is generally designed for wired networks. SSDP operates on multicasting discovery request and advertisement and unicasting a reply in networks. It is a challenge issue for service discovery protocol such as SSDP to provide a stable and effective service in wireless ad-hoc networks. Wired based service discovery protocol does not consider the dynamics of wireless ad-hoc network. In that case, the nodes are freely in or out. Therefore, this paper proposes a flexible SSDP(fSSDP) which is a peer-to-peer(P2P) discovery protocol adopted for wireless ad-hoc Networks. It is implemented on the extension of SSDP. fSSDP supports a functionality that the broadcast area of service discovery dynamically changes with the periodically updated area of advertisement. It is good for reducing messaging overhead caused from the broadcast flooding of service discovery in wireless ad-hoc network.

Recently most of the study about home-networking middleware take the way of web-control through the internet. Although the way of control using wire and PDA also be taken, but does not use standard techniques like UPnP and is limited in the technique controlling simple device. This paper is about the development of a Voice Gateway controlling many kinds of UPnP controlling devices connected to network. voice gateway is consisted of MPC850 module and phone interface and the set-top box, a part of computer in voice gateway is consisted of PSTN interface, information controlling process and the process of UPnP protocol. And I tried to implement this through entire system board.

어떤 조직이나 개인을 상대로 한 인터넷 자원에 대한 분산 서비스 거부 공격이 통상적인 위험이 되고 있다. 이런 공격은 봇넷이라는 수많은 감염되거나 침해된 좀비 머신을 통하여 이루어지고 있다. 우리나라에서는 홈네트워크의 구축으로 광대역 액세스를 가진 개인사용자의 호스트 컴퓨터가 주 공격대상이 될 수 있다. 특히 개인 사용자들은 인터넷 보안에 대한 낮은 인식과 제한된 방어 자원으로 인하여 공격자의 대표적인 타깃이 되고 있다. IRC(Internet Relay Chat) 네트워크를 이용하여 감염된 인터넷 호스트를 제어하고 관리하는 공격들이 증가하고 있어, 이에 대한 대책이 절실히 요구되고 있는 실정이다. 따라서 본 논문에서는 인터넷 호스트들을 감염시키고 원격에서 제어하는 악성 봇/봇넷의 기술 개요에 대하여 기술하고 분석하고자 한다. 또한 최근 증가하고 있는 P2P 봇넷에 대하여도 알아보고자 한다.

Various smart home IoT devices and services while the Internet of things is the development has been provided. The core of the smart home IoT service is that user control the device via the Internet communication. Communication of IoT devices, because most with an IP address within the private network, there is a difficulty in the remote control to control access from outside the network. Any of the methods for remote control, to determine the IP address of each other, there is a UDP hole punching for communication. To ensure the data communication success rate closed to 100%, the UDP hole punching must undergo a process of three stages in some cases. In this paper, to provide a system for managing the remote control policy based on the CEP in order to omit the unnecessary steps on the remote control of IoT devices using UDP hole punching.

In this paper, we have implemented UPnP Devices which emulate a Control Point, a Light Controller, and a Digital TV. The Control Point has been developed on Linux host system by using C language. The UPnP Devices emulating the Digital TV and Light Controller are running on embedded linux developer board. For the development of UPnP Devices, UPnP SDK API Vl.04 made by Intel Co. Ltd. has been ported on Assabet Linux Reference board to implement the UPnP protocol. After we analyze and design some services of Digital TV device, we have applied UPnP Device program to those devices. UPnP SDK vl .04 consists of APIs which support HTTP, SSDP, SOAP, GENA and XML DOM Level-1 that are cores of UPnP protocol. The C program written for the UPnP Control Point has been compiled and executed on Linux-based PC. The embedded system running on Embedded Linux OS has been connected all together through Ethernet which allows IP-based communications. Under this environment, the UPnP programs are being executed on each device. Control Point, when in operational mode, discovers UPnP Devices on the network and displays the device list on the consol. By selecting one of the functionalities of the device services that are displayed on the Control Point, the controllability has been accomplished. The experiment that we performed in this thesis have revealed that the Control Point and UPnP Devices have supported the protocols including SSDP, SOAP, GENA, and DHCP.

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.
