A Retransmission Scheme of Wireless Link Layer for Improving TCP Performance
Yinghua Zhou · 2012
An improved scheme mARQ of link layer selective retransfer is proposed to elevate the TCP performance in the wireless circumstance. This schema sets a limitation to the sum of retransfer times on the basis of the characteristic, that is, each data packet can be divided into several wireless frames ,so that the retransfer time of a frame can be allocated adaptively according to the requirement. The simulation of the system shows that compared with traditional one, the new designed scheme can obtain a larger throughput at a lower error packet rate in the circumstance of high error frame rate, consequently improves the performance of wireless TCP.
