Transmission control protocol (TCP) well known protocol in communication of wireless network and it is also known to
endure from dilapidation in performance in mobile wireless environment. The ii is that the uses of slow start under the wrong
assumption. Error rates on wireless networks are orders of magnitude higher compared to fixed fiber or copper links. Packet
loss is much more common and cannot always compensate foray layer 2 retransmission (ARQ) or error correction FEC).
Mobility itself can cause packet loss. There are many situations where a soft handover from one point to another is not
possible for a mobile end system. While there are a few proposition to streamline TCP within the sight a high piece mistake
rate and versatility, however principally they focus on situations where the TCP sender is a fixed expense. In this paper, we are
concentrating discontinuous detachment issues, the same number of methodologies have been proposed which are affecting
in relieving the antagonistic impact of poor remote channel attributes. We analyze the performance of TCP using a scheme
called ATCP, adopted version of TCP at mobile host. ATCP is designed for improving data transfer performance in 9th
direction i.e. from fixed hosts (FH) to mobile host (NIH) and from MI! to Fit It requires feedback from network layer about
the status of ongoing mobility in terms of connection signal and disconnection signal. Using these signals, it modifies the
action taken when retransmission time expires.
