Title: Backpressure Multicast Congestion Control in Mobile Ad-Hoc Networks

Abstract: In mobile ad-hoc networks, the multicast paradigmis of central importance.It can help to save scarce medium bandwidthif packets are to be delivered to multiple destinations.We consider the problem of congestion control for multicasttraffic in wireless multihop networks. We propose to apply acongestion control concept which is tailored to thevery special properties of the wireless multihop medium: implicithop-by-hop congestion control. The idea,so far only having been considered for unicast traffic,is here generalized to multicast.We implement it in the Backpressure Multicast CongestionControl (BMCC) protocol, with a focus on how to realizeit in combination with geographic multicast routing inthe Scalable Position-Based Multicast (SPBM) protocol.Our evaluation points out a number of highly desirableproperties of the proposed scheme. In particular,it achieves and maintains high throughput and highpacket delivery ratios at low packet latencies, evenin the presence of significant network load.
