Abstract: Aiming at the characteristics of uncertainty and variability in heterogeneous wireless network, this paper proposes a dynamic trust model based on entity credibility. By introducing credibility of the candidate network and credibility of the evaluating entity, malicious behaviors of the dishonest entities are restrained effectively. Time stamp makes the evaluation pay much attention to the most recent performance records. Simulation result shows that the model can accurately evaluate the trustworthiness of the network and effectively restrain the acts of slander and co-fraud.
