Abstract:

In consideration of the user's QoS requirements,optimal utilization of network resources and load balancing,this paper puts forward the corresponding heuristic information and link cost calculation formula to improve the original algorithm model.Some improvements are also made on the basic algorithm to find the global optimal solution accurately and quickly.Results show that the algorithm can greatly optimize the traditional QoS unicast routing algorithm in the entire network performance,especially in load balancing.

Key words: QoS unicast routing;ant system;optimal utilization of resources;load balancing
