Abstract Semiring algebra can be used to compute the trustworthiness between nodes, for it is a good description of the trustworthiness calculation rules issues. However, the existing semiring trust model does not define dynamic issues based on time. A semiring trust model based on the adaptive forgetting scheme is proposed to describe the dynamic of trust, and improve the existing semiring trust model, making up for its shortcoming of not defining dynamic issues. Simulation results show that proposed trust model distinguishes effectively between normal nodes and malicious nodes and resists on-off attacks, which improves the security of Ad hoc networks.
