Network model construction in mobile application layer multicast is a research hotspot following that in non-mobile environment of application layer multicast. Curtail reception and forwarding delay of multicast and structural readjustment strategy in multicast network model are key issues to solve. This paper proposes a Parent-Child High-Continuity Swap Strategy based on small-scale mobile application layer multicast. The strategy is based on the traditional multicast tree constructed, via detecting node parameters periodically,and reduces the...
