Channel Quality Based Adaptation of TCP with Loss Discrimination
, 2002
"... TCP responds to all losses by invoking congestion control and avoidance algorithms, resulting in degraded end-toend performance in lossy environments. In recent years, two approaches have been taken to improve the performance of TCP in such networks. One is local retransmission and the other is end- ..."

present a new wireless TCP protocol-- Endto-end Link State Aware TCP (TCP-ELSA)-- that adjusts the sending rate of a TCP flow according to the wireless link quality, but still provides good congestion control when congestion-related losses occur. The aim of TCP-ELSA is to adapt the sending rate of TCP
The Impact of Multihop Wireless Channel on TCP Performance
, 2004
"... This paper studies TCP performance in a stationary multihop wireless network using IEEE 802.11 for channel access control. We first show that given a specific network topology and flow patterns, there exists an optimal window size W # at which TCP achieves the highest throughput via maximum spatia ..."

spatial reuse of the shared wireless channel. However, TCP grows its window size much larger than W # , leading to throughput reduction. We then explain the TCP throughput decrease using our observations and analysis of the packet loss in an overloaded multihop wireless network. We find out
The Loss-Delay Based Adjustment Algorithm: A TCP-Friendly Adaptation Scheme
, 1998
"... Many distributed multimedia applications have the ability to adapt to fluctuations in the network conditions. By adjusting temporal and spatial quality to available bandwidth, or manipulating the playout time of continuous media in response to variations in delay, multimedia flows can keep an accept ..."

In this paper, we present a new scheme called the loss-delay based adjustment algorithm (LDA) for adapting the transmission rate of multimedia applications to the congestion level of the network. The LDA algorithm was designed to reduce losses and improve utilization
Channel State Awareness based Transmission Power Adaptation for Efficient TCP Dynamics in Wireless Networks
, 2005
"... Although the problem of mal-performance of TCP in wireless scenario has been extensively addressed, an integrated solution has remained undeciphered. Conventionally, measures have been suggested to either adapt or shield TCP from noncongestion losses over the wireless channel. On the other hand, the ..."

Link Quality Estimated TCP for Wireless Sensor Networks
"... Abstract—The irregularity in quality of wireless communication links poses significant research challenges in wireless sensor network design. Dynamic network conditions and environmental factors make an on-line, selfadapted link quality estimation mechanism within sensor nodes a necessity for improv ..."

In addition, for effective adaptation to variable bandwidth, the window feedback is calculated based on the bandwidth–delay product estimation
Channel State Awareness based Dynamic Power Adjustment Policies for improved TCP Adaptation to Wireless Channel
"... Proposed herewith is a novel idea for inter-layer-tunneling across the wireless network stack, linking the transport and the physical layers. The inter-layer interaction is intended to optimize TCP throughput through dynamic power adjustment. TCP remains an attractive protocol in a ubiquitous wirele ..."

improvement policies target either hiding non-congestion losses from the TCP sender or making the sender capable of distinguishing between channel error and congestion related packet losses. The former category of proposals relies on link-layer solutions and has been assessed as not being capable
Packet Loss Recovery for Streaming Video

, 2002
"... While there is an increasing demand for streaming video applications on the Internet, various network characteristics make the deployment of these applications more challenging than traditional TCP-based applications like email and the Web. Packet loss can be detrimental to compressed video with int ..."

"... Abstract — TCP throughput limitations over wireless links have received considerable attention in the last few years. One of the problems is that TCP congestion control interprets packet losses as an indication of congestion, whereas in wireless links, losses could be due to transient link quality d ..."
