A multiobjective model for QoS multicast routing based on genetic algorithm

Usually multiple quality of service (QoS) guarantees are required in most of multicast applications. In this paper, it is formulated as a multiobjective constrained combinatorial optimization problem for a protocol to determine multicast routes satisfying different QoS requirements. We use a multiobjective model and routing approach based on genetic algorithm that optimizes multiple QoS parameters simultaneously. The corresponding results demonstrate that the proposed approach is capable of discovering a set of nondominated routes within a finite evolutionary generation. Its feasibility and performance has been verified.
