Abstract:This paper distributed a mobile agent dynamitic migration algorithm in information retrieve system founded on real ant colony algorithm had two features: a)According to current hosts’ status, agent could independently choice the next host of small load factor to move; b)Agent could find a lowest overhead route to move. The experiments show that agents migration spending can be improved 80% than changeless routing algorithm. And the algorithm dispense with central migration program. The system fault tolerance has been enhanced because of ant colony algorithm being built in each host. ......
