A comparison of mechanisms for improving TCP performance over wireless links
- IEEE/ACM TRANSACTIONS ON NETWORKING
, 1997
"... Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. However, networks with wireless and other lossy links also suffer from significant losses due to bit errors and handoffs. TCP responds to all losses by i ..."

, using throughput and goodput as the metrics for comparison. Our results show that a reliable link-layer protocol that is TCP-aware provides very good performance. Furthermore, it is possible to achieve good performance without splitting the end-to-end connection at the base station. We also demonstrate
Goodput Analysis and Link Adaptation for IEEE 802.11a Wireless LANs

Goodput Enhancement of IEEE 802.11a Wireless LAN via Link Adaptation
- In Proceedings of the IEEE ICC'01
, 2001
"... Abstract — IEEE 802.11a is a new high-speed physical layer (PHY) defined for the 5 GHz U-NII bands as a supplement to the existing IEEE 802.11 wireless LAN (WLAN) standard. In this paper, we give an overview of the IEEE 802.11a Orthogonal Frequency Domain Multiplexing (OFDM) PHY with eight different ..."

Trade-off between cost and goodput in wireless
, 2012
"... We study the cost of improving the goodput, or the useful data rate, to user in a wireless network. We measure the cost in terms of number of base stations, which is highly correlated to the energy cost as well as capital and operational costs of a network provider. We show that increasing the avai ..."

the available bandwidth, or throughput, may not necessarily lead to increase in goodput, particularly in lossy wireless networks in which TCP does not perform well. As a result, much of the resources dedicated to the user may not translate to high goodput, resulting in an inefficient use of the network
Improving TCP Goodput in 802.11 Access Networks
"... Abstract — The widespread deployment of the IEEE 802.11 protocol has made it the de facto standard for wireless network access and allows Internet users to move freely (at least within a hotspot coverage). The convenience brought about by the IEEE 802.11 protocol is also accompanied by new technical ..."

In this work, we seek to enhance efficiency of bandwidth usage for TCP over wireless links and improve TCP goodput. Our insight is that TCP

Maximising single connection TCP goodput by trading bandwidth for BER
, 2003
"... this paper is orthogonal to all these techniques (apart from link-level FEC [4], a similar but less general concept). It operates at the physical or link level, by trading the bandwidth of the wireless hop for packet loss rate. It does not interfere in any way with the normal behaviour of the TCP st ..."

, 2008
"... Abstract-Rate Adaptation for 802.11 has been deeply investigated in the past, but the problem of achieving optimal Rate Adaptation with respect not only to channel-related errors but also to contention-related issues (i.e., collisions and variations in medium access times) is still unsolved. In thi ..."
