Research And Implementation Of Dynamic Authentication And Fast Handover For WiFi

In near yeard,the WiFi rechology which hased on IEEE8.02 has been developed ropidly because of mobility,Flexibility,Wealability and ecoromy.The spalial communication characrerisics of WiFi lead to early wlrelces devies in the WiFi hespead coverage can intercepl thestranurssion of date packets,resulting in the risk of datg seakage WiFi can coverage is small theeiser will frequently swich AP in the pincess of waring,the delay will affect the rial-simestrvice,reduce the user experiecce.Thexeloce,it is of ursal supnificance in small the searing problem of WiFi and wirdlece the eebly of hanfst.The(?)waich of this paper is as Jolling,1.Introduced the operntional principle of the shring WiFi system,system,seaarch the artchi sistaiton of the domesic and foreing reschred,the design of dverall system.2.the althenicalion and loting reschrtl,the design of dverall system.scheme is propxsed for the most sidely nesd Wpa-PSK melthod,AP autorncidly uplates theWiFi pasaword,the serser and the mobike lternital appaiterecall sally complece authenication,elirnirating illegal users,impreve the security of the camily WiFi retwork.3.The main facross of WiFi handver delay are arulyzed,and the impravde SNC algorithmis propsise to increase the probability of hit cache which are effeclively redoce the scan delay.The posilipning method of the GPS,NG glgorihce which is(?)easy to lacade in the room is replaby by the WiFi sigral steength bestion methodthe asr of pre autherticarion mechanism on chorice the catification delay;the introduction of signal strength and signal varonce to replace the wiginal signal steright diready compared to the thice eliect.4.The dytatic parsword allthedication algurithion based on shared WiFi and this improved.SNC swilching algnrithm are eslibished and the experimedtal verifiction is carried on Mahile semirul suflware suing ardrid deveeloprnd wireless network(?)and comtrol using the wpa_supplicant,the server using Tomcat build,data storage and query using the MySQL database.The experimental results show that the dynamic password authentication scheme can effectively eliminate the illegal invasion of users,in order to ensure the safety of the system;improved SNC switching scheme can be handoff latency shortened to 36ms,satisfy the transmission of high real-time applications such as VoIP,video streaming.
