Location management in wireless ATM customer premises networks

This paper introduces a new location management protocol, called LAMPS (Loc ation Agents and Mobile PNNI Scheme), that is suitable for wireless ATM cus tomer premises networks. LAMPS takes advantage of the PNNI routing function ality to advertise the movement of mobile terminals within pre-defined area s. Furthermore, it uses specialized entities to store and retrieve the curr ent location area of the mobile terminals. These entities are located withi n mobility enhanced switches, that provide to mobile terminals connectivity with the rest of the network and supervise the execution of all mobility r elated procedures. In this paper, we compare LAMPS with similar mechanisms and we present the advantages that arise from its application. The efficiency of the protocol is demonstrated by the results of an analytical model. (C) 2000 Elsevier Sc ience B.V. All rights reserved.
