A QoS-aware Multicast Routing Algorithm Based on Ant Agents

摘要

The existing schemes based on ant agents don't take into account the impact of the imprecision of network state information on routing performance. In this paper, we design a novel ant agent-based routing (AAR) model with bandwidth and delay guarantees, in which we consider the influence of state information imprecision. Moreover, on the basis of the model, we propose a new QoS-aware multicast routing algorithm called QMRA. Extensive simulations show QMRA can achieve high routing success ratio, low average packet delay and fast convergence when the network state information is inaccurate.
