The exploitation of trust in virtual environments, on-line services, intelligent pervasive environments and many other scenarios still deserve researchers’ interest. In this work we investigate on how to assess the local (direct) trust a node receives from each of his neighbors. Our proposal is social-based and takes into account both positive and negative experiences as well as the history of past feedbacks and their aging, ensuring good stability also when a node receives hundreds of positive feedbacks briefly followed by few negative feedbacks. Our results are illustrated by performing several simulations on different networks

Abstract

The exploitation of trust in virtual environments, on-line services, intelligent pervasive environments and many other scenarios still deserve researchers’ interest. In this work we investigate on how to assess the local (direct) trust a node receives from each of his neighbors. Our proposal is social-based and takes into account both positive and negative experiences as well as the history of past feedbacks and their aging, ensuring good stability also when a node receives hundreds of positive feedbacks briefly followed by few negative feedbacks. Our results are illustrated by performing several simulations on different networks
