초록

최근 통신, 교통, 의료, 산업시설 등에서 수요가 급증하고 있는 임베디드 시스템은 단순한 임베디드 시스템이 아닌 다양한 임베디드 기기의 동작이 통신을 통해 관찰되고 제어되는 Cyber Physical System(CPS)으로 확장되었다. 또한 구글 글래스, 삼성 갤럭시 기어, 소니 스마트 워치 등의 웨어러블 기기를 활용한 사물인터넷(IoT) 기술활용에 대한 관심이 증가하고 있다. 이러한 상황에서 삼성전자의 스마트홈(Smart Home)과 LG전자의 홈챗(Home Chat)이 잇따라 출시되고 있다. 하지만 이러한 서비스들은 스마트폰과 가전기기간에만 통신이 가능하며 그 이외의 단말과는 통신이 불가능하며 모든 정보는 상업용 포털이 운영하는 글로벌 메시징 서버를 통하여 통신이 이루어진다는 단점이 있다. 본 논문에서는 앞서 언급한 단점을 보완하기 위해 단위공간 기반 실내위치인지망 구축하는 구조를 제안한다. 이를 통해 기기들 및 개개인에 대한 정보가 외부로 유출되는 것을 방지하면서 사물인터넷 채팅을 통해 망 내에 존재하는 모든 단말과의 선택적 통신이 가능하다. 또한 좀 더 범용적인 기기 제어가 가능해지고 개인정보의 외부유출 방지가 가능하다.

Recently, embedded system which demand is explosively increasing in the fields of communication, traffic, medical and industry facilities, expands to cyber physical system (CPS) which monitors and controls the networked embedded systems. In addition, internet of things(IoT) technology using wearable devices such as Google Glass, Samsung Galaxy Gear and Sony Smart Watch are gaining attention. In this situation, Samsung Smart Home and LG Home Chat are released one after another. However, since these services can be available only between smart phones and home appliances, there is a disadvantage that information cannot be passed to other terminals without commercial global messaging server. In this paper, to solve above issues, we propose the structure of an indoor location network based on unit space, which prevents the information of the devices or each individual person from leaking to outside and can selectively communicate to all existent terminals in the network using IoT chatting. Also, it is possible to control general devices and prevent external leakage of private information.
