Abstract In term of the influence of fake recommendation on the accuracy of recommendation trust in wireless Ad Hoc networks, a trust model based on topology transformation was proposed. Mathematic analyses and simulations results reveal that the proposed trust model has convergence characteristic, the fake recommendation-resisted model performs better in terms of packet successful delivery ratio and mean number of packets dropped. Meanwhile, this enhanced trusted model is more suitable for large scale networks.
