Dcf Distributed Coordination Function Computer Science Essay


...Start of the Dcf Distributed Coordination Function Computer Science Essay...

Fragmentation It is the process used in MAC IEEE 8021.11 to break­ing apart a packet into smaller pieces. Fragmentation is process that dividing long frame to several shorter frame. Using this technology because the Wireless LANs have high bit error rates. The probability of losing frame is much higher for wireless links. The 802.11 uses fragmentation to reduce the frame error rate.

802.11 uses fragmentation to reduce the frame error rate. Advantages : To reliability of data exchange between the stations. The uses fragmentation to reduce the frame error rate and fragmentation for larger sized packets improves . Disadvantage: fragmentation will increase the overhead. (Tamer &Khatteb,2009) ..
