The issue of improving networking gateway access capability to adapt to widely promote the application of networking technology perspective, through a variety of existing heterogeneous network communication technology standards described in detail, come with a variety of heterogeneous network convergence perception things gateway generates a variety of communication technology standards used in the Internet of Things in the necessary requirements. Based on embedded technology advantages, combined with the characteristics of the application gateway networking, embedded technology research will be applied to the specific design and networking gateway development. Things gateway you want to achieve with a variety of heterogeneous network access perceived ability, you need a suitable platform for embedded systems-related research and development.According IOT Gateway system needs to have a variety of heterogeneous aware network access capability requirements, through the existing networking gateway architecture for analysis and further deepen after things come up with a novel hierarchical model of the structure of the gateway, all of this new model hierarchy of the corresponding theoretical analysis and study, summarize the things you want to achieve the gateway system can access a variety of heterogeneous network-aware, it is critical that the protocol adaptation layer gateway system can achieve a number of heterogeneous network module for data analysis, and can also be flexibly replace individual modules and load calls. Therefore, in this issue presents a Linux shared library with Linux, called multi-threaded execution of combining theoretical implementations. The program is the individual function modules compiled into the Linux shared libraries for multiple execution threads main dynamic invocation, which not only can analyze the data for multiple modules, but you can not change the case of the main application, by modifying shared library function modules to achieve a flexible replacement load a different perception networks, and the data for the corresponding analytical and extraction.This topic is based on embedded technology networking gateway from hardware to software design, from system software development environment to build into the system software environment migration to application design and development, have carried out a detailed study design. In application design, according to the Linux shared libraries and Linux multithreaded implementations carried out theoretical design of targeted, the final completion of a set of various heterogeneous network access capability perception of things gateway system. In the final demonstration experiment, the site off the concrete used in the laboratory system, intelligent traffic guidance systems and intelligent parking system. Things through the gateway system designed to achieve the induction system and the effective integration of parking system validates the IOT Gateway system can simultaneously read two systems on the perception of network data, thus proving the site off the system to a certain extent to achieve a variety of heterogeneous network-aware access. So this topic of things that are designed to adapt to a variety of network gateway system environment, things will have broad application space, but also will promote the popularization and application of networking technology and development. |
