초록
클라우드 환경이 발달하면서 이질적인 환경에서 IoT 시스템이 다양하게 사용되고 있지만 모든 IoT 장치가 신뢰할 수 있는 프로토콜 및 서비스가 제공되지 않고 있다. 본 논문에서는 서로 다른 이기종의 IoT 장치에서 수집되는 정보를 효율적으로 분류하여 처리할 수 있도록 IoT 클라우드 환경을 n-계층 다단계 구조로 확장할 수 있는 IoT 데이터 관리기법을 제안한다. 제안 기법은 이기종의 IoT 장치로부터 수집되는 데이터를 무선 데이터 링크를 통해 라우팅 정보와 가중치 정보를 전달하여 IoT 정보를 분류 및 처리하는 것이 목적이다. 제안 기법은 IoT 장치로부터 분류된 정보를 해당 라우팅 경로로 전달할 뿐만 아니라 가중치 정보에 따라 우선 순위를 배정하도록 하여 IoT 데이터 처리 효율을 향상시키고 있다. 제안 기법에서 사용되는 IoT 장치는 서로 신뢰할 수 있는 프로토콜을 사용하며, 계층적 구조로 구성된 로컬 클라우드를 통해 로컬에서 다른 IoT 장치에 대한 쿼리는 일정한 비용을 유지하기 때문에 확장성을 보장하는 특징을 가지고 있다.
Abstract
Although IoT systems are used in a variety of heterogeneous environments as cloud environments develop, all IoT devices are not provided with reliable protocols and services. This paper proposes an IoT data management technique that can extend the IoT cloud environment to an n-layer multi-level structure so that information collected from different heterogeneous IoT devices can be efficiently sorted and processed. The proposed technique aims to classify and process IoT information by transmitting routing information and weight information through wireless data link data collected from heterogeneous IoT devices. The proposed technique not only delivers information classified from IoT devices to the corresponding routing path but also improves the efficiency of IoT data processing by assigning priority according to weight information. The IoT devices used in the proposed technique use each other's reliable protocols, and queries for other IoT devices locally through a local cloud composed of hierarchical structures have features that ensure scalability because they maintain a certain cost.y channels of IoT information in order to make the most of the multiple antenna technology.
