Mobility concept for wireless ATM networks [articol]

Abstract

In this paper, the Wireless ATM rerouting procedures are analyzed and categorised, based on a standard network topology, derived from the Wireless ATM reference model. A new operational concept for a mobile ATM network called Mobile Network Architecture based on Virtual Paths (MNAVP), in which the network nodes are connected to each other via preestablished permanent virtual path connections with fixed capacity assignments, is being proposed and described. Finally, the handover hysteresis concept is introduced and a hysteresis gain is defined and calculated as the factor by which the handover rate is reduced through the use of the hysteresis.
