ZIGBEE WIRELESS NETWORK APPLICATION RESEARCH CASE STUDY WITHIN TAIWAN UNIVERSITY CAMPUS

摘要

Using Zigbee techniques as a back bone to develop ubiquitous applications has been warming up while current information technology evolution moving from electrification to mobilization. However, most successful business cases still rely on mobile tools, such as PDA, WIFI, RFID, and GPS, to realize the concept of ubiquitous. The main challenges ahead for making real U-applications on the market are not only the definitions of zigbee specifications and protocols, but the related optimal database build-up and interface design methods. This paper aims to explore the necessary considerations between the gaps within ubiquitous information systems analysis and design stages which could direct the right path for database arrangement This follows the system development life cycle (SDLC) to identify a zigbee wireless network's optimal placement, data flows, and related database design and on line analysis process (OLAP).The case study was undertaken within Hsing-Wu college campus. This ensures the scenario based experiment design could be practical for the further applications. For example, conventional campus touring rely on DM, multimedia and web applications. Most of the cases are just to put business online. There are passively electronic papers allowing users surfing on the net. Partially applications are focus on the mobile services, such as real time navigation and musical instruments. This research aims to fill up the gaps between Mobilizations to U-applications. The main objectives are to build up a U-campus prototype to allow teachers and students getting more interactively information being everywhere. This system could benefit users to find services without asking.The research results reveal that using zigbee to build up a U-campus application are less manpower, capital assets, build-up time than the fixed intranet services. The scenario-based planning, analysis, design and test are realistic for students to realize how to implement an I.T. system in practice. The zigbee geometric placements are testing by three approaches, star, mesh and snowflakes which shows the flexibility of zigbee wireless network.
