This paper presented a swarming agent based intelligent hybrid algorithm (HACOPSO) algorithm using the concept of ACO and PSO. The performance of the proposed algorithm was evaluated through extensive simulation. The results of simulation are compared with two existing algorithms PSOTREE and TGBACA. Our algorithm is found to construct the multicast tree patterns more sensibly such that the tree patterns not only satisfy the QoS constraints, but also tries to minimize the tree cost.
