Distributed QoS Multicast Routing Algorithm Based on ACS
In accordance with multiple constrained QoS multicast routing problem,a new algorithm DQMRA-ACS(Distributed QoS Multicast Routing Algorithm based on ACS) was proposed based on natural parallel of ACO.DQMRA-ACS exchanged and transmitted routing information to obtain local optimum route and avoid cycle during the ant meeting.According to the routing table of pheromone,DQMRA-ACS took advantage of the cooperation of different ant groups to find the multicast routing that satisfied the QoS constraint.The flexible routing switching and locking guaranteed a successful routing connection.The experimental results indicated the feasibility and efficiency of DQMRA-ACS.
