Most of the link rate adaptation algorithms reduce transmission rate on a failed transmission assuming the cause of the loss to be due to radio channel impairment. However, if this failure is due to collision, then lowering the transmission rate in response is unnecessary. This paper proposes a solution to address this problem by augmenting the rate adaptation algorithm with a loss classification...
Protocols such as TCP depend on loss detection and recovery algorithms to provide a reliable data delivery service. TCP detects loss events using either retransmission timeout or receipt of duplicate acknowledgements. Since, TCP does not have any explicit knowledge about the cause of packet loss, it always treats it as a congestion indication and then adjusts sending rate conservatively to maintain...
Responsive transport protocols e.g. TCP, back-off on packet loss. This is because packet loss is by default treated as a sign of congestion. However losses in a wireless network may not only arise from congestion but also because of the inherent characteristics of the wireless medium. If a TCP source assumes a wireless loss as a loss due to congestion and reduces its transmission rate, it fails to...
