The Smart Grid provide a lot of additional service between ICT(Information Communication Technology) and fusion service. The smart grid using various protocol need to use independent middleware system for exchanging information data. The application system of Smart Grid is exchanging information on the almost All-IP system. The current All-IP middleware system consist of SOAP and RESTful. This paper analysis SOAP and RESTful. This result make use of building Smart Grid System.

In the recent years, as smart phones popularized, the number of people who use IMS (instant messaging service) and SNS (social network service) rapidly has increased as the usage of SMS (short message service) relatively decreased. That is why this thesis suggests a contact control service based on Android. It contains an inducing function that calls acquaintances, which were given a score based on the level of familiarity from saved contacts and call logs. And it provides an overall ranking of call log in order to grasp frequently called people. This developed system was tested on Samsung Galaxy S2 and LG Optimus LTE / Android 2.2 which were the main smart phone models.

In this paper, for the smart village project in Geumsan-gun, the problems of the village were derived for the residents. And the business model of the smart village was presented. In the introduction, we looked at domestic cases related to the smart village project. And In November 2019, this paper reflected the results of the resident survey(314) and extracted important smart services using the IPA method. The results of the investigation are as follows. The government's smart village project aims to increase agricultural and fishery production and improve the urban environment. Geumsan residents want to increase agricultural production and develop tourism. The smart village model in Geumsan-gun is promoted in three directions. (1) Smart villages require smart services for crime prevention, parking lots, and public transportation. (2) Smart villages need ICT-based ginseng festivals, smart farms, and tourism services. (3) Smart villages need ICT-based culture and welfare services. The rural areas in Korea are expected to improve the quality of their living environment through the smart village project.

This paper suggests smart gateway structure and functionalities that provide device web service which can be used by user using objectified devices. The smart gateway objectify a physical device in other to provide the device web service in IoT intelligent service. And the paper suggests a mechanism that provide orchestrated service of various devices to user using a concept of service overlay network. and also suggests a interface that provide device web services and the orchestrated service between the smart gateway and a web service platform. In the paper, the objectified devices can be combined with web service objects and device contexts based on the service overlay network, furthermore the objectified devices can provide intelligence and dynamic service in the IoT environment.

Recently, cutting-edge ICT technologies such as artificial intelligence, blockchain, edge computing, and the Internet of Things have been applied in various fields to create new services and a new digital era. Along with these technological developments, various policies are being implemented in Korea to transform the country from a "Smart City" to a "Platform City". We can create new services and values by linking with the Smart City Integrated Platform and Smart Housing Platform. This paper defines a linkage scenario between a Smart Housing Platform and the Smart 119 Emergency Dispatch Support Service, one of the Smart City Safety Nets. We propose a data transmission protocol and a metadata schema for data exchange between the Smart Housing Platform and the Smart City Integrated Platform to provide the Smart 119 Emergency Dispatch Support Service.

Today, the proliferation of various mobile devices, such as smart phones and tablet PC, brought changes in the existing TV viewing behavior. People use smart devices as secondary device while watching TV. Researches on a wide range of services linked with second-screen devices around the smart TV in the home network have been actively conducted. While there exist several Web-related technologies for connections between devices, specialized techniques for a second screen service are quite insufficient. There are still some problems related to the display of contents from multiple devices and the efficient transfer of these contents. Considering the characteristics of broadcasting systems In this study, we focus on a second screen service that permits a dynamic transfer of contents by connecting a television (TV) with mobile devices. Here, we propose a second screen service model to enable the personalization of TV contents by combining the existing broadcasting and Web-related techniques.

The Internet of Things (IoT) is one of the main enablers for situation awareness needed in accomplishing smart cities. IoT devices, especially for monitoring purposes, have stringent timing requirements which may not be met by cloud computing. This deficiency of cloud computing can be overcome by fog computing for which fog nodes are placed close to IoT devices. Because of low capabilities of fog nodes compared to cloud data centers, fog nodes may not be deployed with all the services required by IoT devices. Thus, in this article, we focus on the issue of fog service placement and present the recent research trends in this issue. Most of the literature on fog service placement deals with determining an appropriate fog node satisfying the various requirements like delay from the perspective of one or more service requests. In this article, we aim to effectively place fog services in accordance with the pre-obtained service demands, which may have been collected during the prior time interval, instead of on-demand service placement for one or more service requests. The concept of the logical fog network is newly presented for the sake of the scalability of fog service placement in a large-scale smart city. The logical fog network is formed in a tree topology rooted at the cloud data center. Based on the logical fog network, a service placement approach is proposed so that services can be placed on fog nodes in a resource-effective way.

With Internet of Things (IoT) technology, home environment becomes smarter than ever. Not only smart devices such as smart phone or smart TV, but also various IoT devices including sensor, smart thermostat, and smart scale has now become very common on the market. These devices have connectivity to the Internet, so that user can read data from the device or control the device using Internet technology. However, due to diversity of smart home requirements, device collaboration in smart home remains a challenging task still. Usually smart home is built with various technologies to fulfill its own purpose, and these purposes cover very wide area from controlling low-power sensor devices to controlling high-performance devices like smart TV and smart phone. This variety of smart home requirements makes smart home very complicated due to mixed network architecture, protocol and technology. In this paper, a framework to enable managing and collaborating heterogeneous IoT devices in smart home environment is proposed. Several programming models are defined in the proposed framework to make application development for heterogeneous devices more intuitive. The proposed framework has been implemented as a web service, and a case study with real-world smart home IoT devices is presented.

In this paper, we describe a method for two-way communication service for smart phone integrated with pager which receive various kinds of Internet service information and pushes this information into smart phone to make it available for Internet assess. In this method, the server can push the status data of message boxes into the smart phone and it makes connection to the server automatically. The proposed method will make it possible to manage and excange the information and resources in an efficient manner during idle time, and will provide the potential capabilities of developing a variety of new Internet services for the system.
