Location-based e-campus web services: from design to deployment

In our previous work, we have designed, using a network-based approach, and are currently deploying on Purdue wireless infrastructure, a Web service for location discovery of 802.11-based mobile devices. This paper presents a novel web-based application called remote printing service (RPS) which is entirely built on top of our location discovery service (LODS). RPS is not only capable of locating the nearest printers but also allows mobile users to print without having to install any printer drivers. Most of the time users can print even without having to download the file to the mobile device. We have also designed a prototype for a network-based personal paging system that provides active paging and active email notification capability for mobile users. These value-added wireless services contribute to the building and promotion of an e-campus community.
