Abstract: With the changes and trends of the topological structure of network, dynamic routing will be adjusted automatically for the flow of communications, the quality of its performance is essentialto the performance of the whole network, On the basis of ant colony algorithms, the paper carries out a rational research of dynamic routing, and adopts ant colony optimization algorithms to c ollect the latest information of the network, upgrades the route form and nodal status information dynamically through improving the tactics of choice, solves the load balancing problem of the network, and thus improves the network performance.

Key words: adaptive routing, mobile agent, ant colony algorithm, AntNet
