Undergraduate Projects on Mobile Computing Applications ❯ Wireless Service Discovery

Overview

The goal of this project is to enable the invisible, proximity-based discovery and invocation of services hosted on Jini-enabled devices and computers that use wireless networks for local connectivity. The scope of the project includes 802.11b Wireless LANs and BlueTooth for local connectivity, and Palm computers, laptops, thin-clients, LCD projectors, fax machines, and printers for jini-enabled devices.

Wireless Jini Projection Servie

In this project, an LCD projector is transformed into an invisible, wirelessly accessibe service. Through a web-based client software, wireless devices on the network (and within proximity of the projector) can discover and use the LCD projector and its presentation software. The network environment for this project is a wireless LAN (802.11b) over TCP/IP. Client devices range from Laptops, to Pocket PC's to cell phones. Currently, the client device is a laptop running the Windows 98 operating system and a PCMCIA wireless network card. A client wishing to use this service will execute a program to find all available Jini services on the network. The client then uses a GUI to choose which particular projection service to use (e.g., based on room number) and controls the presentation showing on the projector screen.
