Abstract:
Abstract--- Since TCP cannot distinguish between packet losses due to transmission errors from those due to congestion, TCP tends to perform poorly on wireless links that are prone to transmission errors. Several techniques have previously been proposed to improve TCP performance over wireless links. Existing schemes typically require an intermediate node (typically, a base station) to be TCP-aware. For instance, the Snoop scheme requires the base station to interpret TCP headers and take appropriate actions to help improve TCP performance. This paper proposes an alternative TCP-unaware technique that attempts to mimic the behavior of the Snoop protocol. Performance evaluation shows that the proposed Delayed Dupacks scheme performs quite well. Keywords--- TCP over wireless, transmission errors, endto-end mechanism, link level retransssion I.
