Abstract :
Abstract - In today’s Internet, several variants of TCP are
deployed. These variants differ with respect to their
congestion control and segment loss recovery techniques.
There are schemes like TCP Reno, TCP NewReno to
overcome the congestion problem. On-demand ad hoc
routing protocols respond to network events such as channel
noise, mobility, and congestion in the same manner, which, in
association with TCP, deteriorates the quality of an existing
end-to-end connection. The poor end-to-end connectivity
deteriorates TCP’s performance in turn. So, to address these
problems, two complementary mechanisms are proposed,
that is, the TCP fractional window increment (FeW) scheme
and the Route-failure nOtification using BUlk-losS Trigger
(ROBUST) policy. These two mechanisms result in a
significant improvement of TCP throughput without
modifying the basic TCP window or the wireless MAC
mechanisms.
