In order to improve the accuracy of trust evaluation

a new trust model based on individual experience was proposed. By considering the differences between experiences of individual nodes

relative experience factor （REF） was introduced; then based on REF

a quantitative trust assessment system was constructed. The analysis shows

by introduc-ing the new model

the accuracy of trust evaluation and the feedback trust algorithm are both improved. Furthermore

the feedback trust algorithm is well popularized

and can be used in various trust models.
