Active Cross Layer QoS Routing Algorithm Based on ACO in mobile Internet

In the mobile Internet environment, due to the node´s signal uncertainty, limited energy and mobility, the original passive Internet routing algorithm is no longer applicable. In order to solve this problem, this paper presents an Active Cross Layer QoS Routing Algorithm Based on ACO, which combines mobile agent and ant colony optimization technology. This algorithm can find the link layer, network layer and application layer information actively to achieve optimization QoS routing in a large scale mobile Internet. Finally, two simulating experiments are finished, the simulating results show that this algorithm has better performance than the traditional routing algorithm in cost and response speed.
