Multicast Routing Optimization Algorithm With Bandwidth and Delay Constraints Based on GA

Overview Most of the multimedia applications require strict QoS guarantee during the communication between a single source and multiple destinations. This gives rise to the need for an efficient QoS multicast routing strategy. Determination of such QoS-based optimal multicast routes basically leads to a multi-objective optimization problem, which is computationally intractable in polynomial time due to the uncertainty of resources in networks. This paper proposes a new multicast routing optimization algorithm based on Genetic Algorithms, which find the low-cost multicasting tree with bandwidth and delay constraints. The simulation results show that the proposed algorithm is able to find a better solution, fast convergence speed and high reliability.
