Resumen
The Transmission Control Protocol (TCP) was originally designed to operate on wired networks. However, nowadays
the traffic on wireless networks has grown to a point where
one must take into account the specific characteristics of such
networks when setting up a particular TCP implementation on
them. Particularly, the TCP performance has been studied over
ad hoc wireless networks leading to several new implementations
for TCP. The main issue for TCP on ad hoc wireless networks
is to differentiate between losses due to congestion and losses
occurred at lower network layers. In this paper, we analyze the
TCP performance on two different scenarios of static ad hoc
wireless networks over the DSDV routing protocol. Our findings
show that choosing the right TCP version for ad hoc wireless
networks is a key factor for their performance. We show for the
scenarios we study, that TCP Reno outperforms TCP Westwood
on the average loss rate as well as on the throughput.
