Optimal Multicast Capacity and Delay Tradeoffs in MANETs: A Global Perspective

In this paper, the authors give a global perspective of multicast capacity and delay analysis in Mobile Ad-hoc NETworks (MANETs). Specifically, they consider two node mobility models: two-dimensional i.i.d. mobility, one-dimensional i.i.d. mobility. Two mobility time-scales are included in this paper: fast mobility where node mobility is at the same time-scale as data transmissions; slow mobility where node mobility is assumed to occur at a much slower time-scale than data transmissions. Given a delay constraint D, they first characterize the optimal multicast capacity for each of the four mobility models, and then they develop a scheme that can achieve a capacity-delay trade-off close to the upper bound up to a logarithmic factor.
