This paper addresses the issue of multicast scaling performance in multi channel multi. The authors try to give a comprehensive picture of multicast scaling by investigating both the static and mobile networks, with the metrics being capacity and delay. Radio (MC-MR) networks. Previous literature has indicated that unicast capacity is solely determined by the ratio of channels to interfaces c/m in MC-MR networks. However, in multicast their problem is made more complicated by the interplay among k, c/m and node mobility (if considered in mobile scenario). They characterize their impact on multicast scaling and obtain three remarkable findings from their results.
