In this paper, the authors give a global perspective of multicast capacity and delay analysis in Mobile Ad hoc NETworks (MANETs). Specifically, they consider four node mobility models: two-dimensional i.i.d. mobility, two-dimensional hybrid random walk, one-dimensional i.i.d. mobility, and one-dimensional hybrid random walk. Two mobility time-scales are investigated in this paper: fast mobility where node mobility is at the same time-scale as data transmissions and slow mobility where node mobility is assumed to occur at a much slower time-scale than data transmissions.
