Enhanced Information Retrieval in Social Internet of Things Environment

Abstract

The Internet of Things brings promising challenges. Recently the new paradigm named Social Internet of Things has come. Social Internet of Things is one of novel approaches to integrate Internet of Things and Social Network. In Social Internet of Things environment, the amount of data is greatly increasing as it deals with much more information than ever before. This paper proposes a new information retrieval method in Social Internet of Things environment. We design a new retrieval algorithm using a levelized tiered things structure. The proposed structure is an enhanced tiered structure for supporting the social network of Internet of Thing. A scenario using our method is described. In this scenario, our method shows performance improvement of about 70 percent in the lowest level. Then several experiments are performed. The experimental results show that the proposed method's retrieval performance is better than other existing methods in Internet of Things environment.
