| In mobile ad-hoc networks, the multicast
paradigm is of central importance. It can help to save scarce
medium bandwidth if packets are to be delivered to multiple
destinations. We consider the problem of congestion control for
multicast traffic in wireless multihop networks. We propose to
apply a congestion control concept which is tailored to the very
special properties of the wireless multihop medium: implicit
hop-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 Congestion Control
(BMCC) protocol, with a focus on how to realize it in combination
with geographic multicast routing in the Scalable Position-Based
Multicast (SPBM) protocol. Our evaluation points out a number of
highly desirable properties of the proposed scheme. In
particular, it achieves and maintains high throughput and high
packet delivery ratios at low packet latencies even in the
presence of significant network load. |
