Transfer Delay Analysis of WAP 2.0 for Short-Lived Flows

In this papers an analytical framework for studying the transfer delay of Wireless Application Protocol (WAP) 2.0 for short-lived flows is developed, which is based on a two-state Markova chain that approximates both correlated and independent packet losses. For a given wireless link and protocol parameters, an explicit mathematical expression which yields a good estimate of the WAP 2.0 transfer delay is derived. The analytical results are validated by simulation. It is shown that for large tile sizes (> 30 kB). WAP 2.0 is more sensitive to Hurst accept losses than random l accept losses. It is also shown that the transfer delay of WAP 2.0 can be improved by increasing the size of the initial window in a low.
