Abstract
The features of two important application scenarios, supporting mobile
switches with fixed end users and mobile switches with mobile users, are
dramatically different from those of the traditional wired network
structure. To exploit mobile switches, the location and configuration
management of mobile switches is essential to handle the mobility and
topology change of the wireless/mobile ATM network.
In this paper we address the location management and configuration
problems of mobile switches in an ATM network. We investigate several
aspects of location management problem including architecture to support
switch mobility, mobile switch tracking, and mobile switch locating. We
propose an approach that is based on the Private Network-Network
Interface (PNNI) protocol. We extend the PNNI protocol to enable it to
handle mobile switches. Moreover, we develop analytical models to
determine the tracking and locating costs for mobile switches under the
proposed scheme. The models illustrate the relation between total cost
(tracking cost + locating cost) and peer group size. The models can be
used to derive the optimal configuration for an ATM network with mobile
switches.
Keywords: Private Network-Network Interface (PNNI), wireless communication, network planning.
