This study is a digitalization study based on ICT technology as part of the development of innovative technologies in the new energy industry as a 2050 carbon-neutral policy. It is the development of an oneM2M-based IoT server platform that can be integrated and managed in conjunction with the external interface of each energy facility. It analyzes KEPCO's e-IoT standard specifications through the Power Research Institute's 'SPIN' and develops representative standards, LWM2M and oneM gateway platforms. OneM2M secures and analyzes the recently announced standard for Release 2 instead of the existing Release 1. In addition, the e-IoT standard oneM2M platform is developed based on R2. In addition, it selects the specifications for e-IoT gateway devices that can sufficiently implement KEPCO's e-IoT standards. In addition, a technology and system for developing a high-performance gateway device that considers future scalability were proposed.

FlexRay is a new standard of network communication system which provides a high speed serial communication, time triggered bus and fault tolerant communication between electronic devices for future automotive applications. The speed of FlexRay is 10 times higher than that of CAN. In this paper, FlexRay module is implemented using MC9S12XF512 micro-controller and gateway converting CAN message to FlexRay message. It is shown that the implemented system operates successfully.

As the interest in the wireless internet services is increasing recently, the related technology development is in active progress. According to WAP (Wireless Application Protocol) specification which is currently considered as one of the most powerful international standardizations, mobile terminal and WAP server are supposed to communicate through WAP Gateway. This paper is about the design and implementation of IWAP platform where WAP Gateway and Server are integrated and supported based on Linux. The proposed WAP platform broadly consists of four modules like WAP Gateway, JAVA based Server development environment, WML Tool-Kit, and MUL (Management User Interface) and for bearer network, SMSC (Short Message Service Center) and CSD (Circuit Switched Data) router are considered.

The vehicle network such as CAN, MOST, Ethernet has different protocols. In the case of Ethernet data, when data is transmitted from Ethernet to MOST150, it cannot be treated by Ethernet channel of MOST150, leading to data loss and transmission delays. Thus, this thesis proposes vehicle integration GATEWAY, which can form a network by organically connecting the Ethernet and MOST150 networks and minimize the delay and data losses caused by the differences in bandwidth.

In this paper, we present an integrated management system for WSNs (Wireless Sensor Networks). Each sink node of heterogeneous sensor networks is connected with a gateway. By supporting various hardware platforms and networking models, the gateway is able to collect management information from one or more WSNs and store it in a MIB (Management Information Base). The management system obtains management information from the MIB of the gateway by SNMP (Simple Network Management Protocol) and analyzes it. A manager can have access to the management system through the Web wherever the Internet is available and manage WSNs as well as sensor nodes. We implemented the proposed management system and our findings revealed the practicality of this system.

We introduce the concept of a remote distributed embedded system to integrated fieldbus based control systems in internet/Intranet. As a result fieldbus systems are opened up for remote monitoring, remote maintenance, and remote control applications using state of the art Web-technology. This paper addresses the design of a remote distributed embedded system using Internet and CAN for multi-Induction motor of Building and Industrial field. The fieldbus used the CAN based networked intelligent multi-motor control system using DSP2812 microprocessor. To build such a system, the TCP/IP-CAN Gateway which convert a CAN protocol to TCP/IP protocol and vice verse, was designed. A experimental simulation system consists of a TCP/IP-CAN Gateway in remote place and a command PC ti be connected ti Ethernet.

In this paper, we design and implement middleware service modules of MiTS system architecture which is proposed for integrated shipboard information management. The MiTS system is divided to three layers that are gateway, middleware server and application. The gateway collects and parses information and data, the middleware server integrates the data and stores to a database, and the application displays visual data to users. The service modules provide MiTS middleware services to gateways and applications. We implement the service modules based on international standard IEC61162-4 series and test those.

e-Navigation requires shipboard integrated information system to manage several kinds of data on shipboard. IEC 61162-450 may be adopted for the development of such system. Based on IEC 61162-450, this paper proposes an architecture of shipboard integrated information system, and describes a developed system. The system is composed of NMEA 2000 gateway, wireless sensor gateway, database, monitoring applications. This paper also shows the feasibility of the system through some tests.

Internet of Things spotlighted by the recent growth of the country: the interest in (IoT Internet pf Things) is being maximized. According to the scale of the 2013 Machina Research 2022 yireundago IoT market it is predicting about $ 1.2 trillion. Also the number of IoT devices connected simultaneously to the 2020 worldwide reached about 2.1 billion, and is expected to require about 200 million communications link. Many of these devices in order to manage and operate them efficiently IEEE 802.15.4e, D2D, Beacon, supporting protocols such as Zigbee gateway and network Connectivity to the urgent need for a proactive response to M2M -based operating convert it to a standard protocol being. This paper supports a variety of devices with different protocols and propose the design of intelligent Gateway with integrated features to manage operations.

In this paper, we focus on supporting the convergence of broadcasting and communication in home network systems with E-PON based home gateway. We propose a new architecture to provide broadcasting and data services in integrated home network using overlay transport mechanism in access network and If multicast techniques of IGMP and IGMP snooping in home network. We also detail a set of mechanisms and procedures for home broadcasting service through the home gateway system. Our new scheme is composed of three parts: a) an overlay transmission model of video broadcasting signals (satellite and/or cable TV) and Internet data, b) to select a specific video broadcasting channel and to make of the selected video broadcasting stream into IP multicast packets in tuner/conversion module using multiple tuner system and c) to transfer the converted If multicast packets to L2 switch of home gateway's core module and to send them out to target port(s) by L2 multicast using IGMP snooping.
