Abstract: “In this paper, we propose a bandwidth-efficient multicast mechanism for heterogeneous wireless networks. Reducing the bandwidth cost of an Internet Protocol (IP) multicast tree by adaptively selecting the cell and the wireless technology for each mobile host to join the multicast group. The mechanism enables more mobile hosts, leads to the wireless bandwidth. Besides, the paths in the multicast, connecting to the selected share more common links to save the wireless bandwidth. This supports the”
