Location management in wireless ATM customer premises networks
This paper introduces a new location management protocol, called LAMPS (Location Agents and Mobile PNNI Scheme), that is suitable for wireless ATM customer premises networks. LAMPS takes advantage of the PNNI routing functionality to advertise the movement of mobile terminals within pre-defined areas. Furthermore, it uses specialized entities to store and retrieve the current location area of the mobile terminals. These entities are located within mobility enhanced switches, that provide to mobile terminals connectivity with the rest of the network and supervise the execution of all mobility related 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 Science B.V. All rights reserved.
