الملخص العربي
A reverse direction transmission and block
acknowledgement are the main features to improve the
performance of MAC layer based on next generation wireless
LANs. When the data send it in reverse direction from side A to
B, side B does not need to send separate ACK, it may wait for a
period of time is less than the sender’s time of period to avoid the
retransmission at sender and send a piggyback frame
(ACK+data) this called piggybacking. Piggyback with block
ACK represented in multi data send from side A to B with block
ACK request (BAR), side B send block ACK (BA) piggybacking
with multi data to side A, this called piggybacking with block
ACK. In our scheme here we want to propose a novel reverse
direction transmission using piggyback and piggyback with block
ACK which is divided each data frame send and receive into
subframes and send each subframe separately, if there is an error
happened during the transmission only retransmission the
corrupted subframe instead of whole frame. We want to
implement this work in NS2 simulator. The research
contributions are summarized and the piggyback schemes that
need to be investigated via high speed wireless LANs are also
highlighted.
