For the effective operation of manufacturing system, FMS(Flexible Manufacturing System) and CIM(Computer Integrated Manufacturing) system are developed. In these systems, a machine tool is the target of integration in last 3 decades. In nowadays, the conventional concept of machine tools is changing to the autonomous manufacturing device based on knowledge-evolution through applying advanced information technology in which open architecture controller, high speed network and internet technology are contained. In this environment, a machine tool is not the target of integration but the subject of cooperation. In the future, a machine tool will be more improved in the form of a knowledge-evolution based device. In order to develop the knowledge-evolution based machine tools, this paper proposes the structure of knowledge evolution in M2M(Machine To Machine) and the scheme of a dialogue agent among agent-based modules such as a sensory module, a dialogue module, and an expert system. The dialogue agent has a role of interfacing with another machine for cooperation. To design the dialogue agent module in M2M environment, FIPA-OS and ping agent based on FIPA-OS are analyzed in this study. Through this, it is expected that the dialogue agent module can be more efficiently designed and the knowledge-evolution based machine tools can be hereafter more easily implemented.

최근, 전 세계 주요 국가에서 전략산업으로 육성되고 있는 사물인터넷(IoT : Internet of Things) 기술은 사물과 사물간의 소통이 가능한 상황인식 기반의 미래 인터넷 환경이다. 기존의 연구에는 사람이 직접 명령을 내려 디바이스를 제어하는 P2M(Person to Machine) 방식과 단순 센서 데이터를 통한 단일 디바이스 제어방식이 있다. 하지만, IoT의 일종인 Machine Socialization은 각각의 디바이스들이 디바이스 내부 기능정보를 이용하고, Device Manager를 통하여 전체적인 시나리오를 전개하는 M2M(Machine to Machine)방식의 디바이스 협업 시스템이다. 본 논문에서는 기존의 P2M의 시스템을 M2M의 시스템으로 변화시키기 위한 Machine Socialization의 시스템의 알고리즘을 제안한다.

이 연구는 소비자들이 사물지능통신(Machine-to-Machine: 이하 M2M) 기술을 활용한 가전제품을 구매 및 사용하고자 할 때, 어떠한 요인들이 그 제품을 선택하는 데 영향을 미치는지 고찰하였다. M2M 가사기술은 모바일 인터넷을 통해 가전제품과 가정 내 각종 시설을 원격제어하거나 전자동으로 작동시키는 새로운 정보통신기술로, 여성들의 가사노동 부담 해소와 사회 참여를 지지할 수 있는 기술이다. 이 논문은 이러한 점에 주목하여 성별, 소득 수준, 기혼여성의 취업 여부, 모바일 인터넷 기기의 보유 여부 등 4개의 독립변수가 소비자들의 M2M 가전제품의 구매 및 사용의사와 어떠한 상관관계에 있는지 분석하였다. 연구 결과 M2M 가전제품의 구매와 사용을 모두 결정할 수 있는 변수는 '스마트폰과 태블릿PC 등 모바일 인터넷 기기의 보유 여부'로 확인되었다. 이와 달리 기혼여성의 취업 여부는 구입의사에만 영향을 미쳤고 소득수준과 성별 요인은 거의 영향을 미치지 않았다. 이러한 결과는 '주부의 취업, 소득, 성별 변수에 의해 가사기술이 도입된다'는 기존 연구와 다른 새로운 성과이다.

In FMS (Flexible Manufacturing System) and CIM (Computer Integrated Manufacturing), machine-tools have been the target of integration in the last three decades. The conventional concept of integration is being changed into the autonomous manufacturing device based on the knowledge evolution by applying advanced information technology in which an open architecture controller, high-speed network and internet technology are included. In the advanced environment, the machine-tools is not the target of integration anymore, but has been the key subject of cooperation. In the near future, machine-tools will be more improved in the form of a knowledge-evolutionary intelligent device. The final goal of this study is to develop an intelligent machine having knowledge-evolution capability and a management system based on internet operability. The knowledge-evolutionary intelligent machine-tools is expected to gather knowledge autonomically, by producing knowledge, understanding knowledge, reasoning knowledge, making a new decision, dialoguing with other machines, etc. The concept of the knowledge-evolutionary intelligent machine is originated from the machine control being operated by human experts' sense, dialogue and decision. The structure of knowledge evolution in M2M (Machine to Machine) and the scheme for a dialogue agent among agent-based modules such as a sensory agent, a dialogue agent and an expert system (decision support agent) are presented in this paper, with intent to develop the knowledge-evolutionary machine-tools. The dialogue agent functions as an interface for inter-machine cooperation. To design the dialogue agent module in an M2M environment, FIPA (Foundation of Intelligent Physical Agent) standard platform and the ping agent based on FIPA are analyzed in this study. In addition, the dialogue agent is designed and applied to recommend cutting conditions and thermal error compensation in a tapping machine. The knowledge-evolutionary machine-tools are expected easily implemented on the basis of this study and shows a good assistance to sensory and decision support agents.

Recently, ICT technology has been evolving towards an M2M (Machine to Machine) environment that allows communication between machine and machine from the communication between person and person, and now the IoT (Internet of Things) technology that connects all things without human intervention is receiving great attention. In such a network environment, the communication network between object and object as well as between person and person, and person and object is available which leads to the sharing of information between all objects, which is the essential technical element for us to move forward to the information service society of the era of future ubiquitous computing. On this paper, the protocol related to DTMNs in a Sparse M2M environment was applied and the improved routing protocol was applied by using the azimuth and density of the moving node in order to support a more efficient network environment to deliver the message between nodes in an M2M environment. This paper intends to verify the continuity of the study related to efficient routing protocols to provide an efficient network environment in the IoT and IoE (Internet of Everything) environment which is as of recently in the spotlight.

As a new business concept, machine-to-machine (M2M) communications are born from original telemetry technology with the intrinsic features of automatic data transmissions and measurement from remote sources typically by cable or radio. M2M includes a number of technologies that need to be combined in a compatible manner to enable its deployment over a broad market of consumer electronics. In order to provide better understanding for this emerging concept, the correlations among M2M, wireless sensor networks, cyber-physical systems (CPS), and internet of things are first analyzed in this paper. Then, the basic M2M architecture is introduced and the key elements of the architecture are presented. Furthermore, the progress of global M2M standardization is reviewed, and some representative applications (i.e., smart home, smart grid and health care) are given to show that the M2M technologies are gradually utilized to benefit people's life. Finally, a novel M2M system integrating intelligent road with unmanned vehicle is proposed in the form of CPS, and an example of cyber-transportation systems for improving road safety and efficiency are introduced.

최근 이동통신 시스템 및 통신기술의 발달로 인해 사람 대 사람 통신에서 사람 대 사물, 사물 대 사물(M2M) 통신으로 변화하고 있다. 여기서 사물은 네트워킹 기능을 가진 장치들을 의미한다. 또한, M2M 서비스가 활성화 될 경우 무수히 많은 M2M 장치가 이동통신 네트워크에 접속할 것으로 예상되며 이로 인해 M2M 장치를 식별할 수 있는 식별자 부족 문제가 발생할 것으로 예측하고 있다. 따라서 본 논문에서는 이동통신 기반 M2M 서비스 환경에서 무수히 많은 M2M 장치를 식별할 수 있는 그룹 식별자 기반의 새로운 M2M 식별체계를 제안한다. 제안한 M2M 식별 방법은 향후 M2M 장치 식별자 부족 문제 해결할 수 있는 방법으로 활용될 수 있다.
