Multicast applications for large-scale Mobile Ad hoc NETworks (MANETs) require an efficient and effective Quality of Service (QoS)-aware multicast model. The new requirements to guarantee QoS are high availability and good load balancing due to limited bandwidth and transmission power of Mobile Nodes (MNs). We propose a logical Hypercube-based Virtual Dynamic Backbone (HVDB) model for QoS-aware multicast communications. In this model, high fault tolerance and small diameter of hypercubes are the basis for high availability, and regularity and symmetry of hypercubes contribute to good load balancing. Based on this model, we design proactive local logical route maintenance, summary-based membership update, and logical location-based multicast routing algorithms in large-scale MANETs.
