Impact of mobility on resource allocation in ATM networks

In this paper, we have proposed a tree based Virtual Embedded Network architecture to address resource reallocation problem for mobile users connected to an arbitrary topology ATM backbone network. The approach helps us significantly reduce the resource reallocation rate on different links of ATM network for both linear and two dimensional arrangements of access points. We show that the resource reallocation rate may be further reduced by very small over-allocation of resources. We have proposed and evaluated two specific schemes for better understanding of this trade-off.
