Piggyback Scheme over TCP in Very High Speed Wireless LANs: Review

摘要

When the data packets transferred in duplex directions from part A to part B, and the data arrives at B, instead to sending a control frame from B to A, receiver B waits until the network layer at B send the next packet to A, and the Acknowledgment is attached in data frame from B to A using the field of Acknowledgment in the data frame header. so the acknowledgment got a free ride in the data frame, this technique known as piggybacking. One of the most advantages for piggyback scheme is improving the efficiency, which is reducing the overhead and increase system throughput. In this paper, we want to provide an overview of a research progress in piggyback scheme over wireless LANs. The research contributions are organised and summarized and it highlights the piggyback schemes that need to be investigated via high speed wireless LANs.
