Research Of Milti-mode Heterogeneous Embedded Gateway With A Variety Of Closs Distance Wireless Access

With the development of network technology,Information resource sharing is the direction of future development in the future,The cost, speed and other was limitation in The existing home oriented and other application environment gateway or platform relative to a variety of access technologies and heterogeneous modes.For the existing problems,The subject plan uses ARM-Linux architecture,Research on the integrated gateway based on the recent wireless access technology such as heterogeneous wifi, Zig Bee, Bluetooth,Build the overall architecture of the software and hardware,Supported by multiple access technologies;Heterogeneous wireless network integration,At the same time we considering the combination of Internet of things business, for the use of PC, mobile phones and other useful support.This paper analyzes the research status of embedded heterogeneous multi-mode gateway at home and abroad.Aimed at the limitations of the existing single access system platform and the characteristics of single common gateway network function, module separation and low level of integration, realizing the WiFi, Zig Bee, Bluetooth and other wireless access from close range on the basis of completion of high-performance embedded system platform, and proposing a software and hardware implementation scheme of embedded heterogeneous multi-mode gateway.Secondly, the use of open embedded technology, based on the analysis of several radio access technology protocol, research and develop a embedded gateway based on protocol conversion between different types of networks for protocol conversion between the two kinds of wireless network data forwarding to achieve interoperability between different networks, realizing integration of heterogeneous networks, smart phones and other terminals can be connected with the platform via Wifi, GPRS to achieve more efficient transmission of information between the user and the network.Finally,This paper through the design of a custom protocol implementation between Wi Fi and Zig Bee, WiFi and Bluetooth network data transmission based on the realization of the two kinds of network fusion scheme,and analysis and test the performance of the system as a whole.the results have been applied in theenterprise and provides the help to improve the product performance.
