Internet of Vehicles (IoV) is a subset of Internet of Things (IoT) and it is an infrastructure for vehicles. Therefore, IoV consists of three main network including inter-vehicle network, intra-vehicle network, and vehicular mobile internet. IoV mainly used in urban traffic environment to provide network access for drivers, passengers and traffic management. Accordingly, many research works have focused on network technology. But, recent concerted efforts in academia and industry point to paradigm shift in IoV system. In this paper, we proposed a knowledge base for intelligence service in IoV. A detailed design and implementation of the proposed knowledged base is illustrated. We hope this work will show power of IoV as a disruptive technology.

In the end-user domain of an IoT environment, there are more and more intelligent M2M devices that provide resources to create and share application services. Therefore, it can be very useful to manage trust by transferring the role of the existing centralized service provider to end users in a P2P environment. However, in a decentralized M2M computing environment where end users independently provide or consume services, mutual trust building is the most important factor. This is because malicious users trying to build malfunctioning services can cause security problems in M2M computing environments such as IoT. In this paper, we provide an integrated analysis and approach for trust evaluation of M2M application services, and an optimized trust evaluation model that can guarantee reliability among users of the M2M community.

최근까지 정보 기술 분야에서는 유비쿼터스(Ubiquitous)라는 용어가 크게 유행한 척이 있다. 현재는 다소 식상하게 들리는 용어일지도 모르지만 사물의 지능화와 통신화라는 유비쿼터스 개념은 이미 우리의 생활에 깊이 파고 들어왔다. 최근 유행하는 IT 기술인 스마트폰이나 지능형 전력망, 와이파이, 소셜 네트워크, 센싱 데이터 처리 기술과 개념은 이러한 유비쿼터스 기술의 대표적인 사례로 볼 수 있다. 국내에서 는 이러한 유비쿼터스라는 개념을 유비쿼터스 센서 네트워크(Ubiquitous Sensor Network: USN)라는 용어로서 2004년부터 정보통신부 혹은 지식경제부의 적극적인 지원에 힘입어 많은 기술적/산업적 성과를 이루기도 했다. 하지만 이러한 USN은 센서네트워크 개념으로 제한적으로 오용되는 경우가 많았다 이에 본고에서는 이러한 유비쿼터스 환경을 실현하는 사물의 지능화/통신화에 대한 기술 동향과 보안 기술을 논하기 위해서 USN과 거의 비슷한 개념이지만 국내외적으로 더욱 보편적으로 사용되고 있는 IoT(Intemet of Things) 용어를 사용할 것이며, 이러한 IoT에 대한 기술 동향과 보안 기술을 논하고자 한다.

생활 속 사물들을 유 무선 네트워크를 이용하여 상호 연결하고 정보를 공유하는 환경을 사물인터넷이라고 한다. 즉, 인터넷을 기반으로 모든 사물을 연결하여 사람과 사물, 사물과 사물 간의 정보를 상호 소통하는 지능형 기술 및 서비스로서 기존의 유선 통신 기반 인터넷 및 모바일 인터넷보다 진화된 다음 단계의 인터넷을 의미한다고 볼 수 있다. 이러한 사물인터넷은 가전제품을 비롯한 전자기기뿐만 아니라 원격검침, 헬스케어, 스마트홈, 스마트카, 스마트팩토리 등의 다양한 분야에서 가정 및 산업용으로 응용되고 있다. 본 논문에서는 임베디드 디바이스를 사용하여 가정의 전자기기를 사용환경을 구성하고 이러한 장치들과 소통하고 제어할 수 있는 웹 기반의 플랫폼 환경에 대하여 제안한다.

Recently, in digital agriculture, the types and utilization of greenhouses based on IoT are spreading, and greenhouses are being modernized, enlarged, and even factoryized using smart technology. However, a specific standardization plan has not been proposed according to the equipment for data collection in the smart greenhouse and the size or shape of the greenhouse. In other words, there is a lack of standard data for facility equipment, such as the type and number of sensors and equipment according to the size of the greenhouse, the type of greenhouse construction film and materials suitable for crops and carbon neutrality. Therefore, in this study, the suitability of the implementation, installation and quantity of IoT equipment for data collection was tested, and some standard technologies were presented through the implementation of data collection and communication methods. In addition, impact strength, tensile, tear, elongation, light transmittance, and lifespan issues for PE, PVC, and EVA, which account for about 90% of existing greenhouses, were presented, and the shape, size, and environmental problems of greenhouses made of films were presented. presented in the text. In this research paper, a standardized carbon-neutral modular smart greenhouse using nano-material film was implemented as a solution to environmental problems such as greenhouse size, farm crop type, greenhouse lifespan, and film, and its performance with existing greenhouses was analyzed and presented. Through this, we propose a modularized greenhouse that can be expanded or reduced freely without distinction in the size of the greenhouse or the shape of farmhouse crops, and the lifespan is extended and standardized. Finally, the average characteristics of greenhouses using existing PE, PVC, and EVA films and the characteristics of greenhouses using new carbon-neutral nanomaterials are compared and reviewed, and a plan to implement an expandable IoT greenhouse that supports carbon neutrality is proposed.

In order to make the IoT ecosystem more usable and friendly to general users, the interaction between the users and platforms/devices and its UX must be improved. In this study, a web-based rule engine system to help users intuitively interact with the various devices and services in IoE (Internet of Everything) platform is proposed. The proposed system consists of web interfaces and UI components for creating and managing rule-based scenarios using sensors, actuators, and external services in an intuitive way. Also, a rule management module for automatically translating the rules from the web interface into Nools rule engine compatible ones is proposed. Finally, we show the usability and feasibility of the proposed system by demonstration of rule-based use cases of IoT devices and external services.

From the last past decade, the Internet of Thing (IoT) area has attracted a lot of attention from researchers. It is said to be a promising technology with great impact in people life, since it redefines the relationship objects have with Human and between themselves. It allows objects to gather data from the real world and communicate with others through the internet. This enabled many opportunities for service providers, companies, factories, environmental monitoring, healthcare, smart cities, and soon. Therefore, today, IoT is densely used in various domains of life, and knows an exponential growth. However, although many advancements have been achieved, several challenges keep causing issues and still need to be overcome. This paper gives an overview on the current trend issues in IoT on which researchers are focusing. It's also explores different proposed frameworks to allow the application of cognitive computing as an integrated process of an Internet of things (IoT) systems, to bring a great advanced in the way machine may communicate with human and their surroundings. This is known as cognitive IoT (CIoT), which allows machines to produce a human-like behavior, then providing enhanced level of capabilities to IoT.
