  • The fault-tolerance routing problem is one of the most important issues in the application of the Internet of Things, and has been attracting growing research interests. In order to maintain the communication paths from source sensors to the macronodes, we present a hybrid routing scheme and model, in which alternate paths are created once the previous routing is broken. Then, we propose an improved efficient and intelligent fault-tolerance algorithm (IEIFTA) to provide the fast routing recovery and reconstruct the network topology for path failure in the Internet of Things. In the IEIFTA, mutation direction of the particle is determined by multi-swarm evolution equation, and its diversity is improved by the immune mechanism, which can improve the ability of global search and improve the converging rate of the algorithm. The simulation results indicate that the IEIFTA-based fault-tolerance algorithm outperforms the EARQ algorithm and the SPSOA algorithm due to its ability of fast routing recovery mechanism and prolonging the lifetime of the Internet of Things.

  • Due to its potential, the Internet of Things (IoT) begins to be used in the industrial field. Nevertheless, although the concept called the Industrial Internet of Things does not know a widely accepted definition, it is based on the existing technology, and introduces the IoT in the industrial environment through the compliance with specific additional requirements and by integrating various fieldbuses with distinctive features, from the real-time point of view. The aim of this paper is to propose a practical architecture for the Industrial Internet of Things. The proposed architecture is designed around the Data Distribution Service for Real Time System (DDS) middleware protocol, and it is organized on four levels. Between these levels, it is defined standard interface, and they can be developed independently. For this reason, the architecture is scalable because at the middleware level, the DDS can be replaced by other middleware systems. At the final, it is performed a comparison between several middleware systems used in the proposed architecture.

  • The Internet of things is the infrastructure that can communicate with each other by exchanging information by installing antennas that can communicate with all things in the world. The reason why the Internet of Things is the core of the Fourth Industrial Revolution is that data is collected through the Internet to be. Technology of things Internet and Trend of Things Internet IoT (Internet of Things) is a concept that enables internet connection and communication between devices equipped with various sensors. It is the core IT trend of lot, technology such as big data, mobile, cloud And to provide information for the development of the industrial environment through research on the importance of the Internet of things, the core of the Fourth Industrial Revolution and the processing and analysis techniques of Big Data. By providing various security measures and future technologies, This study was conducted to contribute to management.

  • In this study, we developed a Hedonic Model for Retargeting Advertising Based on Consumer-centerd IoT space for offering useful, interest, and interactive information to consumer. And most existing relative researches about Internet of Things but, this paper focusing on the Type of information, humor, and interactive and analyze the attitude and clicks intention to Retargeting Advertising Based on Consumer-centerd Internet of Things. According to the results, humor Advertising is positively related to attitude and click intention toward Internet of Things Advertising. But information Ad and interactive Ad affect positive to click intention. This is mean that click intention is more immediate reaction of consumers in the IoT space. Therefore Future research will be designed in a more interactive elements that can lead to positive reaction of consumers on the Internet of Things be more effective if you advertise advertising.

  • Many people have used a internet at various purposes. Internet have been used the optimal space to share informations by information producer or consumer. But, recently, through the development of networks and devices, The Internet is expanding beyond PCs and mobile devices into enterprise assets such as field equipment, and consumer items such as cars and televisions. The Internet of Things will enable forms of collaboration and communication between people and things, and between things themselves, hitherto unknown and unimagined. This paper presents various meanings of IoT, and describe the electronic and car domain of internet of things.

  • In general, IoT(Internet of things) designate the intelligence technologies and services which interact all necessity information between human and things, things and thing and things and systems with all things connecting through the internet based. The smart home in present of IoT environment fuses the daily supplies/equipment which needs to use for the private life with the internet of things that is the fruit of the converged business through all most private consumption related in vastly. The concept of smart home has been built around early 2000s due to the spread of high speed internet and advanced of smart electronics and internet, furthermore influencing by the enhancement of wireless network and smart devices, it is advanced as a smart home within the internet of things environment. Smart home service inside the house which most closely implemented with personal life is being developed and advanced in various forms. These developments may exert a positive effect, but if it does not resolve the security issues for the smart home service, then it may cause a big plague of privacy and personal life.

  • Recently, many IoT(internet of things) products are emerging on the market and information technology companies are competing on the areas of internet of things standardization and platforms. This paper introduces many researches, standardizations, platforms on internet of things. Because of that, as the interest in this area out focused, many kinds of technology and new service are being exploited in this field. Therefore, we conducted a review research based on the internet of things. Also, this study was targeted a total of 34 research papers that are setting up the related internet of things among the research papers published in domestic academic journals since 2010. In this review, the studies related internet of things showed that the most is studied between 2014 and 2015. This study suggests practical and theoretical implications based on the results.

  • 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.
