The Research on Searching Path Algorithm of Interoperable Recommendation Trust Based on MMAS

With the problem of derivation of trust path in the trust management, the trust relationship transmission and searching for trust path were studied in the paper. On the one hand, based on graph theory and TOPSIS (technique for order preference by similarity to ideal solution) method, interoperable recommendation trust model was established in the paper. On the other hand, given the dynamic and complex natures of interoperable trust web, searching path algorithm of interoperable recommendation trust based on MMAS (Max-min ant colony algorithm) was studied which can meet the dynamic change of interoperable trust web.
