Research of Multicast Server Selection Based on Ant Algorithm

A novel model has been proposed in this paper, it considers a pair of clients as the smallest gene, which was assigned secretion respectively based on proper modification of ant algorithm. We transformed the problem of client selecting server to that of server selecting client. And we adopted GT-ITM as Internet topology generator to generate transit-stub model topology for simulation. In the case of large-scale network topology, the simulation results show that the modified ant algorithm performs better than other heuristic algorithms such as the widest path and the optimized widest path ones.
