Design And Implementation Of Remote Control Wifi Router System Based On Openwrt

With the growing popularity of smartphones and smart devices,there is an increasing demand for access to Internet using mobile devices.In order to meet the needs of users,all major operators have introduced 4G networks in recent years,but only on the operators 'mobile networks cannot meet the needs of users' access to the Internet anytime and anywhere,In this case,the wireless router can provide users with a convenient and stable network environment.Commercial WiFi can meet the needs of three groups of consumers,businesses and router platform operators.Consumers can get more affordable and better Internet services;businesses can attract more users using free WiFi,improve business traffic and turnover;operators are able to get more data through commercial WiFi,making profits by providing more additional functions.Therefore commercial WiFi has become a mobile Internet entrance for major companies.In this application scenario,this thesis designed a WiFi router system based on Openwrt.Wireless users get free Internet access after connecting WiFi and certificated,merchants can manage router configuration,set up Internet access time,set up blacklist and whitelist users,and configure WiFi parameters.Operators can remotely release tasks to upgrade router firmware and the data reported by router,and so on.This article mainly introduces the design and implementation of the WiFi router system from three aspects:network control,local management and remote management.Part of the network control function mainly introduces the design of Iptables firewall,and introduces WiFi Internet interception and WiFi pop-up window design.By combining the firewall with the web authentication technology,a secure WiFi system used in the company's intranet is realized.The local management function section introduces the design framework of the local management interface.Combining with Openwrt's system parameter configuration and firewall functions,the function of configuring WiFi parameters and setting firewall policies through the local management page is implemented.The remote management function introduces the long connection and interaction system between the router and the cloud platform,fulfills the task of pushing and upgrading the cloud platform,and realizes the functions of upgrading the WiFi router firmware version,reporting router data,upgrading system software,and remotely controlling,which provide a cloud platform management solution for the growing Openwrt application.Finally,this paper has carried on the overall test to the system function,has designed a set of router pressure test system which has realized the test of the load limit of the router in the circumstance of guaranteeing the access quality at the same time.The scheme effectively reduces the test complexity and time period and improves the test efficiency.
