Abstract:
We study multicast capacity for a large-scale spatial inhomogeneous mobile network consisting of n ad hoc nodes. Under our mobility model, the stationary spatial distribution of a node is non-uniform; each node spends most of the time in a certain region, and rarely (or never) visits out of such region. To characterize the inhomogeneity of the mobility model, we define an activity exponent c and two clustering parameters (m(n),r(n)), where c 2 [0, 1] measures the strength of node mobility, m(n) denotes the number of clusters, r(n) denotes the radius of the cluster. We classify the mobility into two cases according to the strength of mobility of each node, called strong and weak mobility, respectively.
