WLAN Data Ihuza

Ihuza ryamakuru ya WLAN ikoreshwa nkurwego rwingenzi rwo kohereza amakuru. Kugira ngo wumve WLAN, ugomba no kubimenya birambuye. Binyuze mu bisobanuro bikurikira:
Muri protocole ya IEEE 802.11, MAC sublayer yayo ikubiyemo uburyo bwo kugera kubitangazamakuru bya DCF na PCF:
Ibisobanuro bya DCF: Gukwirakwiza ibikorwa byo guhuza ibikorwa
Mugihe DCF nuburyo bwibanze bwo kugera kuri IEEE 802.11 MAC, ikoresha tekinoroji ya CSMA / CA kandi ikaba muburyo bwo guhatana, mugihe iyi node yohereje amakuru, izakurikirana umuyoboro. Gusa iyo umuyoboro udafite akazi ushobora kohereza amakuru. Umuyoboro umaze kuba ubusa, node izategereza igihe cyagenwe hagati ya DIFS.
Niba ihererekanyabubasha ryizindi ngingo ritumvikanye mbere yuko DIFS irangira, igihe cyo gusubira inyuma cyabazwe, ibyo bikaba bihwanye no gushyiraho igihe cyo gusubira inyuma;
Ipfundo ryerekana umuyoboro igihe cyose kibonye umwanya: niba risanze umuyoboro udafite icyo ukora, igihe cyo gusubira inyuma gikomeza igihe; bitabaye ibyo, igihe gisigaye cyigihe cyo gusubira inyuma cyarahagaritswe, kandi node irongera igategereza ko umuyoboro uhinduka ubusa; nyuma yigihe DIFS irangiye, node ikomeza kubara uhereye mugihe gisigaye; Niba igihe cyo gusubira inyuma kigabanutse kuri zeru, amakuru yose yoherejwe. Nuburyo bwo gukosora uburyo bwo kohereza amakuru.
PCF: Igikorwa cyo Guhuza Ingingo;
PCF itanga umuhuzabikorwa wo gutora imbuga zose zo kohereza cyangwa kwakira amakuru. Ubu ni uburyo budahiganwa, bityo amakimbirane yo kugongana ntazabaho, ariko arashobora gukoreshwa gusa mumiyoboro yabantu idafite umugozi hamwe nibikorwa remezo bimwe na bimwe.
Ibyavuzwe haruguru ni itangizwa rya WLAN Data Link Layer yazanywe na Shenzhen Haidiwei Optoelectronics Technology Co., Ltd.ibicuruzwa.
