Middleware Platform for Ubiquitous Location Based Service.

Over the past few years, several studies have been made on Location Based Service (LBS) middleware platform about performance and architecture. And service area is extended as mobile client is an indispensable factor in LBS. Although LBS middleware platform process a large transactions to cope with interoperability and real time processing, current LBS system use an existing Geographical Information System (GIS). In this paper, we propose an Open LBS Middleware Platform (OLMP) which is possible to process a large moving object and to support different mobile clients such as PDA and cellular phone. We describe the system architecture of an OLMP and a main memory DBMS. A proposed OLMP is consisted of open LBS components, mobile gateway, and main memory DBMS. [ABSTRACT FROM AUTHOR]
