Analysis of Feedback Evaluation for Trust Management Models in the Internet of Things

The Internet of Things (IoT) is transforming the world into an ecosystem objects that communicate with each other to enrich our lives. devices’ collaboration allows creation complex applications, where object can provide one or more services needed for global benefit. information moves nodes in a peer-to-peer network, which concept trustworthiness essential. Trust and Reputation Models (TRMs) are developed goal guaranteeing actions taken by entities system reflect their values prevent these from being manipulated malicious entities. cornerstone any TRM ability generate coherent evaluation received. Indeed, feedback generated consumers has vital role as source trust model. In this paper, we focus on generation propose different metrics evaluate it. Moreover, illustrate new collusive attack influences received services. Simulations real IoT dataset show importance impact proposed attack.
