본 논문은 실내에서 홈 거주자의 위치를 인식하기 위해 근접성을 이용한 위치 추적 시스템 환경을 제안하고자 한다. 이를 위해 기존 실내의 고정된 위치에 있는 구조/시설물 및 가전제품의 ON/OFF 스위치를 이용하며 기타 추가적인 스위치 및 센서를 부착하여 개폐동작이 일어날 때 발생되는 신호를 검출하여 실제위치를 얻는다. 발생되는 신호는 Pull-up 저항을 이용한 신호 검출 방법으로 눌려진 스위치나 센서에서 발생된 아날로그 신호를 검출한다. 검출된 신호의 고유한 ID값은 Sensor TMO로 송신되어 수집된다. 수집된 센서ID는 소켓통신을 이용하여 홈서버인 실내위치추적시스템으로 보내질 뿐아니라 원격 모니터링 GUI를 통해 실내 거주자의 위치를 GUI의 가상공간 좌표와 매핑된 홈 거주자의 위치를 보인다. 본 논문에서 제안한 실내위치추적시스템은 홈 거주자의 위치를 주기적으로 모니터링하고 거주자의 이동 패턴과 활동 상황을 파악하여 헬스케어 정보로 활용할 예정이다.

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.

Nowadays, the interests about medical service and health concerting, in other words "Healthcare",are increasing. For healthcare, one of the most convenient and populated methods is taking nutritional supplements like vitamin everyday. According to social currency, we realize ' Automatic Pill Dispenser (APD)' in order to make the storage of pills easy and to help people take pills steadily periodically. First, the APD alerts at the time when the user sets. To prevent polluting pills, if the ultrasonic sensor recognizes user hands, and then after the APD distributes pills through activating the motor. If there are more the APDs, for example, hospitals can manage manpower more efficiently. Furthermore, If it is recorded which and how much pills are distributed automatically, It can be expected that people can take the pills more efficiently and healthfully.

In this paper, we implemented a home IoT system based on MQTT protocol. In this system, data are collected from sensors in real time and transmitted to the server system. Based on collected data, home devices could be controlled automatically or manually. By using the MQTT protocol, we were able to see the data values of sensors collected in real time according to the topic setting. We implemented a system that automatically sets up home devices based on topic data, and it worked. The system is expected to be useful in applications that require monitoring and tracking of data in real time.

In this paper, we propose a methodology to deal with the IOT system gradually as the use of effective systems such as electronic devices, healthcare, smart cars, smart home, remote meter reading and telemedicine closely related to our real life in the IOT system An IOT integrated account solution is needed as a way to address these needs as the demand grows for the need to identify and manage how users access and use the system for what period of time and at what point in time. We propose the communication algorithms for endpoint system, IOT system management rights policy, user information, and how to apply them to IOT system smart car and smart home on each object internet.

A smart home provides services that its inhabitant needs or wants, by integrating and simultaneously controlling various devices and sensors. In this study, we focused on a smart-home system for people with disabilities and for elderly people. We introduced a new type of system for real-time analysis of body posture of the inhabitants of a smart home. The system includes the concept that offers remote healthcare or medical services by using a 3D tilt sensor for recognizing the static and dynamic postures of inhabitants in real time. It consists of a smart-home server and a 3D tilt sensor, and it uses wireless technology to communicate with the inhabitants and thus enhance their mobility. The smart-home server includes the inference engine that differentiates the dynamic postures from the static ones. Finally, we also demonstrate the usefulness of the proposed system by applying it to a real environment.

With the development of IoT technology, various cloud computing-based services such as smart cars, smart healthcare, smart homes, and smart farms are expanding. With the advent of a new environment, various problems continue to occur, such as the possibility of exposure of important information such as personal information or company secrets, financial damage cases due to hacking, and human casualties due to malicious attack techniques. In this paper, we propose a message communication protocol for smart home-based secure communication and user data protection. As a detailed process, secure device registration, message authentication protocol, and renewal protocol were newly designed in the smart home environment. By referring to the security requirements related to the smart home service, the stability of the representative attack technique was verified, and as a result of performing a comparative analysis of the performance, the efficiency of about 50% in the communication aspect and 25% in the signature verification aspect was confirmed.

With the development of Internet of Things (IoT) technology, the combination of ICT and medical services has been increasing to improve the quality of medical services. Using the IoTs, we can collect personal health information continuously in a patient's everyday life. We expect that this will improve the quality of medical service through analysis. However, the problem of ensuring the protection of personal information within the personal health information has been hampering the research, development, and application of such services. Other problems include lack of IoT devices and lack of user convenience for collecting health information about a patient's everyday life. Therefore, in this study, we construct a daily health information management service that can collect the health related information at any time and store this data in personal storage. This data is then only provided to the healthcare worker when necessary. We built a test bed for an IoT-based smart home platform and are currently conducting user experiments. Based on the results of this study, we are attempting to provide a high quality medical trial service based on daily health information through linkage with medical device manufacturers, medical clinics, insurance companies, etc. We expect the proposed health information management service will contribute to the revitalization of smart health care services via activating various health related IoT devices and analyzing daily health information.

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.
