Design And Research Of Embedded Network Optimization Probe Based On WLAN

With the development of the Internet, WLAN (Wireless Local Area Networks),low-cost, high efficiency of the network deployment and operational mode gradually isaccepted by users. At the same time, how to network in AC, FIT AP, the mobile terminalunified management, and high-efficiency wireless devices for mass maintenance, carry outeffective monitoring of the quality of network transmission, each operator faced with thechallenge. Design of a new practical network optimization probe device is of greatsignificance.The main work is as follows:(1) Tracking the domestic and foreign research status of WLAN network optimizationprobe device, the paper put forward its own design. This design programs in closeconnection with the wireless network testing and optimization features to meet therequirements of the market for WLAN network optimization.(2) We studied the system hardware selection, completed the choice of processor andthe choice of the wireless network card.(3) We made a full research on the optimization design of probe system applicationsoftware for WLAN network. Completed the choice of operating system, the choice ofprogramming language, research division of the functional structure of applicationsoftware, and gives the return value definition of the application software.(4) Application software function module is designed. Including the capture module,packet filtering module, hardware detection module, wireless environment scanningmodule, service dial test module.(5) The network communications and maintenance module of the software is designed.Including background data communication module, configuration module, Webmaintenance module and the public module function guidelines.(6) We described the system test cases design and configuration content of the WLAN network optimization probe system. Including the design of the main system functions testcases, probe the system configuration of static IP address and system configurationinstructions. Finally, a summary of the work and further work outlook.
