Wireless mesh networks are self-organized and usually without centralization control. Protocols in such networks are also required to be distributed for robustness and scalable. In this paper, localized mechanisms are adopted to support multicasting in wireless ad hoc networks without throttling unicast flows. The proposed scheme combines the layered multicast concept with the routing-based congestion avoidance idea to reduce the aggregated rate of multicast flows when they use excessive bandwidth on a wireless link. The author's analysis and sweeping simulations show that the fully localized scheme proposed in this paper is effective in ensuring the fairness of bandwidth sharing between multicast and unicast flows in wireless ad hoc networks.
