In this paper, the authors study the multicast capacity of wireless ad hoc networks with infrastructure support. The network under study is termed as hybrid wireless network, where L-Maximum-Hop resource allocation strategy is adopted. There are n uniformly deployed normal wireless nodes and m regularly placed base stations dividing the network region into m cells. This result provides a meaningful guide for the design of hybrid wireless networks. Moreover, they demonstrate that it is more efficient to adopt infrastructure mode than ad hoc mode, because infrastructure nodes can cover the whole cell and broadcast to nodes more efficiently.
