A Spectrum Of TCP-Friendly Window-Based Congestion Control Algorithms
White Papers This paper presents a comprehensive study of a new spectrum of window-based congestion controls, which are TCP-friendly as well as TCP-compatible under RED. The control rules are parameterized so as to ensure that the resulting protocol is TCP...

Constant Congestion Window Approach For TCP-Effect On Fairness
White Papers This paper indicates that a fixed congestion window performs better than a TCP Reno implementation. TCP was designed to work well in networks with low channel error rates. Wireless networks on the other hand are characterized by frequent...

On Setting TCP's Congestion Window Limit In Mobile Ad Hoc Networks
White Papers This paper addresses one aspect of this endeavor: how to properly set TCP's Congestion Window Limit (CWL) to achieve optimal performance. Improving TCP performance has long been the focus of many research efforts in Mobile Ad hoc NETworks (MANET).

Analyzing The Receiver Window Modification Scheme Of TCP Queues
White Papers Explicit Congestion Notification (ECN) and Active Queue Management (AQM) Schemes such as Random Early Detection (RED), Adaptive Random Early Detection (ARED) and BLUE queues have been proposed for TCP/IP networks to compensate network congestion.

A TCP-Like Adaptive Contention Window Scheme For WLAN
White Papers This paper proposes and investigates a simple self-adaptive contention window adjustment algorithm for 802.11 WLAN. It presents simulation and analytical results showing that the new algorithm outperforms the standard 802.11 window adjustment...

On TCP Performance In Multihop Wireless Networks
White Papers First, there exists an optimal value for TCP congestion window size, at which the TCP throughput is maximized. However, TCP does not operate around this optimal point, and typically grows its window much larger; this leads to decreased throughput...

Modified TCP Congestion Control Algorithm For Throughput Enhancement In Wired-Cum-Wireless Networks
White Papers The key idea proposed in this paper is to determine the Optimal Congestion Window for a TCP Sender in a particular network scenario (that corresponds to the fair share of that connection) and keep this congestion window a constant to a point where...

The Impact Of Multihop Wireless Channel On TCP Throughput And Loss
White Papers The analysis and simulations show that, given a specific network topology and flow patterns, there exists a TCP window size W*, at which TCP achieves best throughput via improved spatial channel reuse.

TCP Symbiosis: Congestion Control Mechanisms Of TCP Based On Lotka-Volterra Competition Model
White Papers The paper changes the window size of a TCP connection in response to information of the physical and available bandwidths of the end-to-end network path. This paper proposes TCP Symbiosis, which has a robust, self-adaptive and scalable congestion...

TCP With Sender-Based Delay Control
White Papers This paper describes a congestion control method for TCP that adjusts the transmission rate of a TCP connection by changing not only the congestion window size as in normal TCP, but also by delaying the transmission of packets at the sender.

Known TCP Implementation Problems
White Papers When a TCP begins transmitting data, it is required by RFC 1122, 4.2.2.15, to engage in a "slow start" by initializing its congestion window, cwnd, to one packet (one segment of the maximum size). The minimum of cwnd and the receiver's advertised...

Improving TCP Startup Performance Using Active Measurements: Algorithm And Evaluation
White Papers TCP Slow Start exponentially increases the congestion window size to detect the proper congestion window for a network path. This paper presents a new TCP startup algorithm, called Paced Start, that incorporates an available bandwidth probing...

TCP Over Multihop 802.11 Networks: Issues And Performance Enhancement
White Papers So, one of the critical sources of lowering TCP throughput lies in the TCP window mechanism itself. To fix this problem, a fractional window increment (FeW) scheme for TCP is proposed to prevent the over reaction of the on-demand routing protocol...

Congestion Control: SCTP Vs TCP
White Papers This paper characterizes an inefficiency in the current speciation of SCTP's congestion control, which degrades performance (more than necessary to be 'TCP-friendly') when there are multiple packet losses in a single window.

Optimizing TCP Retransmission Timeout
White Papers This paper shows that the optimal RTO that maximizes the TCP throughput need to depend also on the TCP window size. Intuitively, the larger the TCP window size, the longer the optimal RTO. Delay spikes on Internet paths can cause spurious TCP...

A State Feedback Control Approach To Stabilizing Queues For ECN-Enabled TCP Connections
