  Abstract:  QoS routing is used in networks to find feasible paths that simultaneously satisfy multiple (QoS) constraints. The scaling difficulties in conventional shortest-path routing can be addressed using hierarchical routing and state aggregation. State aggregation gives rise to an approximate representation of the network, which can lead to inaccurate path selection. We evaluate in this paper our hierarchical routing protocol, called Macro-routing, that we introduced in [4]. Macro-routing can distribute the route computation efficiently throughout the network using mobile agents. This allows it to process more detailed information than in conventional hierarchical routing protocols and so increases the likelihood of finding the best path between source and destination.

Key words and phrases. QoS routing, hierarchical routing.
