Description
Summary:Today’s electrical and electronic gadgets have become smarter and intelligent. These devices such as sensors, actuators, RFIDs are becoming part of our fabric. Internet of Things (IoT) and Social networking paradigms are not new. The increased pervasiveness has resulted not only in human to thing communication but also thing to thing communication. A new paradigm integrating IoT and Social Networks has emerged in recent years called the Social Internet of Things (SIoT) where objects are not only smarter but also socially conscious. Social Internet of Things is analogous to social network of intelligent objects. Trust is considered as a crucial factor in SIoT for objects to establish reliable autonomous communication. This paper proposes a Trust Management scheme for Social Internet of Things where trust between objects is computed based on Direct Observations, Indirect Recommendations, Centrality, Energy and Service Score of the object. The proposed trust model outperforms the existing trust models leading to a better application performance. The trust model is also tested in the presence of On Off selective forwarding attacks. Experimental results prove that the proposed model is reliable and defendant against On Off selective forwarding attacks.
