White Paper The congestion detection mechanism of congestion control based on dynamic window flow control, which is widely used for reliable window protocols such as TCP, is well-known to be simple, but it may raise false alarms: a sender usually interprets... [03 Jul 2008]
Estimation of Bluetooth TCP Performance With Adaptive Packet Type in the Burst Error Model
White Paper As a result, a TCP sender may reduce the size of its congestion window unnecessarily when a packet is lost due to random error. In a radio network, a packet loss can be due to interference from other electromagnetic wave having the same frequency. [03 Jul 2008]
Queueing Analysis of Simple FEC Schemes for IP Telephony
White Paper Some mechanisms must be introduced at the sender and/or at the receiver to compensate for packet losses and jitter. Audio quality is still however an open problem due to the loss of audio packets and the variation of end-to-end delay (jitter). [03 Jul 2008]
Get mobile addicts out of the BlackBerry jam
Comment The only mitigation is the sender's explanatory signature line of "sent from my BlackBerry". As the number of mobile email users has grown rapidly in recent years - along with their increasing dependency - the impact of any loss of service is... [21 Feb 2008]
Different Mechanism for Improving TCP Performance Over Wireless Links
White Paper The sender identifies the loss of a packet either by the arrival of several duplicate cumulative ACKs, triggering a fast retransmission, or by the absence of an ACK for a timeout interval equal to the sum of the smoothed roundtrip delay and four... [14 Jan 2008]
Robust TCP Congestion Recovery
White Paper Moreover, the new recovery scheme requires only a slight modification to the sender side of TCP implementation, thus making it widely deployable. This paper presents a new robust TCP congestion-recovery scheme to handle bursty packet losses while... [14 Jan 2008]
TCP Westwood: End-to-End Congestion Control for Wired/Wireless Networks
White Paper TCP Westwood (TCPW) is a sender-side modification of the TCP congestion window algorithm that improves upon the performance of TCP Reno in wired as well as wireless networks. In fact, TCPW performance is not very sensitive to random errors, while... [14 Jan 2008]
Adding Network-Layer Intelligence to Mobile Receivers for Solving Spurious TCP Timeout During Vertical Handoff
These schemes require only minor modifications to the network layer of mobile receivers and no change to the TCP protocol and the TCP sender. With the help of Mobile IP/IPv6 and soft handoff, on-going TCP sessions can remain active and handoff... [09 Jan 2008]

Evaluating TCP With Corruption Notification in an IEEE 802.11 Wireless LAN
White Paper It has been suggested to enhance the performance of TCP over wireless links by adding a checksum that covers the packet header, enabling the TCP receiver to detect errors in the payload and inform the sender of such occurrences. [26 Dec 2007]
Data encryption brought into focus by HMRC
Comment The sender would have to use software that encrypts the data using strong algorithms encrypting sensitive data at source and tightly controlling and monitoring the way people access the database. The issue of data encryption has been brought into... [21 Dec 2007]
CTCP: Improving TCP-Friendliness Over Low-Buffered Network Links
White Paper Compound TCP (CTCP) is a sender-side improvement for TCP in high-speed and long distance networks. CTCP is a synergy of delay and loss-based congestion control, effectively combining them to achieve good efficiency, RTT fairness and TCP-friendliness. [19 Dec 2007]
De-Randomizing Congestion Losses to Improve TCP Performance Over Wired-Wireless Network
White Paper This paper proposes a simple biased queue management scheme that "De-randomizes" congestion losses and enables a TCP receiver to diagnose accurately the cause of a loss and inform the TCP sender to react appropriately. [19 Dec 2007]
TCP WestwoodVT: A Novel Technique for Discriminating the Cause of Packet Loss in Wireless Networks
White Paper Towards this issue, the paper proposes a novel technique, WestwoodVT (WestwoodNR based on TCP Vegas buffer Thresholds), which is a sender-based TCP congestion control mechanism for discriminating the cause of packet loss to enhance the performance... [19 Dec 2007]
TCP With Header Checksum Option for Wireless Links: An Analytical Approach Towards Performance Evaluation
White Paper Basically, the TCP sender responds to these losses as if they were due to congestion in the network, and reduces the congestion window unnecessarily. In earlier work, it has been shown that adding a TCP header checksum is very useful in... [19 Dec 2007]
