Optimization And Application Of A Distributed Multifunctional Wireless Router

With the popularization of the wireless network technology and the artificial intelligence,more and more home devices,such as desktop,laptops,mobile phones,air conditioners,and refrigerators are connected to the network in the form of wireless connection.Therefore,it is important to have stable signal connection and efficient data transmission.When the home devices connect to network,its performance can be affected by many factors,such as user housing size,room layouts,and building materials,etc.Which will lead to poor signal,slow transmission speed,and even signal blind-spot.The best way to solve these problems is to select high power wireless routers.However high power is accompanied with high radiation which affects the healthy.Based on this,it is urgent for the emergence of the customized wireless router.There are two types of wireless deployment solutions.One is AC-AP deployment which can realize unified management and configuration,and it is mainly used in enterprise level units.The other is single-point deployment which has the advantages of quick configuration,convenience,and it is suitable for home situation.Because of the diversity of the home environment and the increase in user demand,the new wireless home routers emerge as the market require,and this approach has avoided the drawbacks that conventional routers include.In this paper,a home-based distributed multi-function router is proposed,which is deployed by AC-AP distribution.While ensuring the full coverage of wireless signal intensity and network performance,intelligent roaming technology is added to realize the experience of two layer roaming zero packet loss.According to the demand for green and healthy,the AP emission power is adjusted to minimize the radio AP radiation.This paper divides the design and implementation of distributed multi-function routers into two parts:The first part is the design of AC controller.It uses single quad-core embedded processor of CTEON ? III CN70XX/CN71 XX,which is an entry-level enterprise platforms of home networking and storage device.Based on the CAPWAP protocol,the module configuration of update,tunnel establishment and tunnel delay detection are designed to ensure the reliability and diversity of the connection between AC and AP.The second part is the design of the AP.AP is based on the hardware platform of the AR9331 processor with high stability and low power consumption MIPS architecture.It uses the source code to compile hardware and boot program U-boot.Then it is migrated to the hardware development platform,so that the system software can call the underlying hardware.In this part,firstly the system development environment is set up,which uses the trunk version of the Open Wrt system to develop the system,and it can achieve distribution,power adjustment,and intelligent roaming on the system functions.Then,the customize Lu CI themes is used to achieve system customization;At last,the wireless driver of the kmod-cfg80211-3.10.49.-1 is connected to the system firmware.Finally,we implement the full set of functions and test the system performance in the real application situation.
