초록
IoT(Internet of Things) 환경은 다양한 사용자 애플리케이션을 만드는데 사용할 수 있는 여러 가지 서비스에 대한 액세스를 제공하여 사용자의 요구 사항을 충족시킬 수 있어야 한다. 그러나 수많은 이기종의 장치 및 잠재적인 자원 제약과 같은 IoT 환경적 특징으로 QoS 문제가 발생하게 된다. 본 논문에서는 SOA기반 IoT 시스템에서 사용자간 신뢰관계를 반영한 QoS 예측 방법을 제안한다. QoS예측의 정확도를 높이기 위해, 사용자간 신뢰 관계를 분석하여 사용자들 사이의 유사성을 파악하고 이를 기반으로 QoS를 예측하도록 한다. 연결중심성을 계산하여 신뢰를 강화하도록 하였으며, 실험을 통해 QoS 예측의 향상이 이루어지는 결과를 얻을 수 있었다.
Abstract
The Internet of Things (IoT) environment must be able to meet the needs of users by providing access to various services that can be used to develop diverse user applications. However, QoS issues arise due to the characteristics of the IoT environment, such as numerous heterogeneous devices and potential resource constraints. In this paper, we propose a QoS prediction method that reflects trust between users in SOA based IoT. In order to increase the accuracy of QoS prediction, we analyze the trust and distrust relations between users and identify similarities among users and predict QoS based on them. The centrality is calculated to enhance trust relationships. Experimental results show that QoS prediction can be improved.
