Internet has been used by the unique space that users share various informations. Due to the development of Information communication technology(ICT), many devices were introduced. These devices are connected by Internet each other. The Internet of Things(IoT) use the Internet for the interconnection of the things. Studies for 'Internet of Things' progress extensively on today. Therefore, we studied the smart industries domain related with Internet of things. In this paper, three domains among the smart industries were described. These three domains such as smart city, smart home and smart health are related with our life. Therefore, we described many actual cases in three domains based on Internet of Things.

To share the informations, we have been used Internet by the unique information transfer method. Many devices are showed and have been used in our various fields because of ICT(Information communication technology) development. The various devices are connected by Internet to send or receive the informations. We call this situation to The Internet of Things(IoT). It use the Internet for the interconnection of the various things. Studies on IoT progress extensively on today. Therefore, we studied a healthcare field related with Internet of things. In this paper, we described many actual cases such as smart bottle of medicine and smart pill in healthcare domains based on IoT.

Peer-to-Peer (P2P) overlay networks have drawn much research interest in the past few years because they provide a good substrate for large-scale applications in the Internet. In this paper, we introduce the use of anycast, a new "one-to-one-of-many" communication method in the Internet, to solve the following common problems of P2P overlay networks: load-balancing, topology-awareness, system partitioning, and multi-overlay interconnection. We also give an analysis of the features and limitations of the recently deployed anycast infrastructures in the Internet for supporting P2P overlay networks.

The Internet of Things (IoT) is the interconnection of uniquely identifiable embedded computing devices within the existing Internet infrastructure. IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications and covers a variety of protocols, domains, and applications. Time information is a critical piece in the IoT to support its requirements. This paper reviews conventional time keeping mechanisms in the Internet and presents issues to be considered for combining time and data in the IoT.

인터넷 접속료 정산방식은 그동안 피어링과 트랜짓 모델이 주로 활용되어 왔으나 인터넷 트래픽의 폭발적 증가, OTT 서비스 확산 등으로 망 이용대가의 적정 분담을 위해 발신자지불방식(SPNP: Send Party network Pay) 등 새로운 정산모델 도입이 필요하다는 주장도 제기되고 있다. 본고에서는 인터넷 접속료 정산방식으로 활용되어 온 피어링과 트랜짓 정산모델의 특징과 도입배경, 다양한 피어링/트랜짓 변형 모델을 살펴보고, 최근 유렵 통신사업자 협회가 제안한 발신자지불방식 정산모델의 제안 배경 및 ITU, OECD 등 국제기구에서의 논의 동향을 검토해보고자 한다.

We proposed the detection method and security threat under ubiquitous surroundings. We described the problems that must be faced in the design of such a wireless protocol model. The internet is a natural and universal means of providing this interconnection. The networking of these ubiquitous computing devices is driven by the synergy between three trends. In this paper, we analysed the security model under ubiquitous surroundings.

The basic idea of IoT(Internet of Things) is interconnection and cooperation with a variety of things in real life such as Radio-Frequency Identification(RFID) tags, sensors, mobile phone, etc, through internet. IoT technologies which applied to these fields consist of sensor network technology and middleware, application. Currently, IoT technology is applied to various fields such as health care, home care, automotive, transportation, construction, agriculture, environment, food, and etc, based on its technologies. This paper focuses on discussion of the game planning method in IoT environment. In order to achieve this purpose, first, introduce the IoT technologies. Second, propose a game design elements and considerations in IoT environments. It can help for game developers by using IoT technologies.

In this paper, we designed a IoT(Internet of Things) sensor block embedded lightweight house deck structures that can be implemented using Carbon Fiber Reinforced Polymer(CFRP). Deck-Sensor interconnection interface block via IoT connectivity Hub that can mount external environmental sensors such as fire sensors on the Deck body itself was also proposed. Additionally we described the configuration of devices for data acquisition and analysis based on IoT environmental detection sensors that can be commonly installed and used on these deck bodies. On the other hand, received sensing data based monitoring user interface(UI) also developed and used for sensing data analysis for remote monitoring center. Through the implementation of such IoT-based sensor data transmission and collection analysis devices and UI software, this paper confirmed the availability of CFRP based lightweight House deck structure and possibility of CFRP deck-based IoT sensor data networking and analysis functions.

Multistage Interconnection networks (MIN) for the high performance computing and communications must be efficient and reliable. While a number of fault tolerance schemes have been developed, some of them are not efficient enough with respect to all evaluation measures or overheads of others are too significant. In this paper we develop a new efficient fault tolerant MIN which displays high reliability and fault tolerance capability using a simple structure. Structure and reliabilities of Enhanced Cube Network are evaluated and compared with previous designs to show the effectiveness of new design.

Despite the growth in Internet users, demand for multi-medial, large data files and resulting explosive growth in data traffic, there has been lack of investment in Middle-Mile, interconnection of various networks, resulting in bottleneck effect, which is acerbating. One strategy to overcome such network bottleneck is Content Delivery Network (CDN). CDN does not achieve efficient delivery of large file data through physical improvement/increase in network capacity, but by delivering large file contents, the cause of bottlenecks, from distributed servers. Since it is impracticable to physically improve networks capacity to accommodate the growth in internet traffic, CON, by strong CPs contents at cache servers deployed at major ISPs networks, is able to deliver requested contents to the requesting Web clients without the loss of data and long latency.
