QoS Multicast Routing Based on Firefly Algorithm

QoS multicast routing problem is a nonlinear combination optimization problem, which is difficult to get the global solution by using the traditional algorithm. In this paper, we use the Firefly Algorithm (FA) to solve the multi-constrained QoS multicast routing problem and QoS-FA algorithm is presented. FA is a novel heuristic stochastic algorithm and has been applied to many optimization fields. The simulation results show that the QoS-FA algorithm can search the optical multicast tree and has better performance.
