The Multicast Capacity of Large Multihop Wireless Networks
Overview This paper considers wireless ad hoc networks with a large number of users. Subsets of users might be interested in identical information, and so the authors have a regime in which several multicast sessions may coexist. The paper first calculates an upper-bound on the achievable transmission rate per multicast flow as a function of the number of multicast sources in such a network. It then proposes a simple comb-based architecture for multicast routing which achieves the upper bound in an order sense under certain constraints. Compared to the approach of constructing a Steiner tree to decide multicast paths, the construction achieves the same order-optimal results while requiring little location information and no computational overhead.
