Design and Implementation of a Location-Based Service Platform

Location-based service (LBS) is a great potential application for the mobile communications. Design and implementation for location-based service platform is presented in this paper. This platform is divided into client side and server side. Client side of this platform software is developed based on the following techniques: mobile SVG based JSR226 and JSR179 specification, Bluetooth, mobile media, map slicing, map layering, and J2ME. Sever side is developed by XML, J2EE, and MySQL. This platform can provide the following services: information of map segment query, shortest path to destination query by Dijkstra algorithm, bus route query, and route navigates. A general architecture and modular for location based services is also provided based on this platform with interactive, multimedia and location-aware. Many valuable LBS can be enabled on this platform by some suitable modification.
