چکیده (انگلیسی):

This paper presents a new bidirectional transmission protocol
with single data frame to computing the performance of MAC layer based
on IEEE 802.11n. As high as 600 Mbps of physical data rate is achieved in
IEEE 802.11n where high data rate the current MAC layer leads to high
performance overhead and low performance of throughput and designing
the MAC layer still ongoing to achieve high performance throughput. In
this study, a new bidirectional transmission protocol with single data frame
has been proposed called BTDF bidirectional transmission data
fragmentation, which is divided each data frame from sender to receiver
and reverse into subframes and send each subframe, Packets those exceed
the size threshold are divided into fragments also where the corrupted
subframe will be retransmitted during the disruption of transmission. We
have implemented this scheme in NS2 simulator to show the results for
TCP and HDTV traffics and compared with literature.
