Abstract

In this paper, we present a scalable data delivery infrastructure for such IoT computing environment where we need a common platform where data providers share their diverse sensing data and applications can easily access and receive such data from providers. For efficient data delivery, this paper proposes a new delivery path management technique that take advantage of diverse consumer QoS when building bandwidth-efficient delivery paths. We perform primitive experiments on the path construction and reconstruction which may be major overhead of the scalable infrastructure. The results show that the proposed infrastructure achieves a high level of scalability, and demonstrates that the management overhead is not significant.

최근 사물인터넷(IoT) 기술의 발전과 함께 수많은 센서와 소형 구동장치들로 구성된 새로운 컴퓨팅 환경이 도래했다. 본 논문은 이와 같은 IoT 기반 컴퓨팅 환경에서 데이터 제공자들과 소비자들 사이에 센싱 데이터를 쉽게 공유하고 접근하도록 지원하는 공유 플랫폼으로서, 확장성있는 데이터 전송 기반구조를 제안한다. 확장성과 효율성을 제공하기 위해, 이 논문은 특히 소비자들 간의 서로 다른 QoS 요구사항을 활용하여 전송 대역폭을 효과적으로 활용한 전송 경로를 구성하는 방법을 제시한다. 전송경로 구성과 재구성 과정이 제안하는 구조의 가장 큰 오버헤드로 판단되므로, 본 논문에서는 그 비용을 산정하는 기본적인 실험을 수행하였는데, 결과는 제안된 구조의 우수한 확장성에 비해 오버헤드는 비교적 적은 것으로 확인되었다.
