Embedded Information Appliances, Wireless Gateway And Implementation

Along with the rapid development of information technology, lots of home network protocols emerge in endlessly to satisfy the need of home automation. Based on Project "the research and implement of open embedded platform in home network" from Yunnan Province, we analysis Bluetooth protocol thoroughly, and give solutions on composing a home network and designing the Information Appliance Gateway. These solutions are based on the ideas of using Bluetooth technology, Information Appliance technology, Embedded technology, and Internet technology. In a situation that home network develops into inevitably, we carry on research thoroughly, and some valuable results are yielded.In the introduce part of dissertation, we summarize the evolution of Information Appliance, describe the characteristics and application of the main home network protocols, compare with Bluetooth protocol, and also discuss the importance and rapid development of Bluetooth protocol in home network.Bused on Bluetooth Specification 1.2, we explain the intact frame and function of Bluetooth protocol suites, sum up ideas of Bluetooth programming, and analysis the key protocol programming.Considering the performance, price, and developing cycle factors, we propose the way on building a home network and designing the Information Appliance Gateway. We also build the platform for hardware and software developing, describe the details of transplanting BlueZ to Linux OS, and design the main function modules of Information Appliance Gateway. On Linux OS, these process and results have certain reference value on designing the Gateway using other different wireless protocols.
