Preferred Abstract (Original):
Transmission control protocol has been adapted to
various types of wireless networks (e.g., IEEE 802.11 WLAN, 3G cellular
and ad hoc networks). However, wireless transmission control protocol
flows are much shorter than wired flows due to the time varying
characteristics of wireless networks. Hence, transmission control
protocol performance in these networks is determined by the start up
effects such as connection establishment. Several analytical models were
proposed to describe the steady-state behaviour of short-lived
transmission control protocol flows in wired networks, while few similar
studies targeted wireless networks. Moreover, almost all of the
previous models did not investigate the effect of heterogeneity (e.g.,
link speed and segment loss probability) of wireless networks on the
end-to-end performance of transmission control protocol flows. In this
paper, a recursive and analytical model is developed and used to
determine the performance of short- lived transmission control protocol
flows in heterogeneous wired-cum-wireless networks in terms of average
completion time. Two different schemes are proposed to solve the
wireless loss problems by the end hosts, namely, end-to-end scheme and
connection division scheme. The proposed analytical model has been
validated by means of simulations using NS-2 simulator. Performance
results show that the proposed model is in close analogy with values
obtained from the analytical model. As such, the proposed model can be
used to accurately tune many parameters that affect the behaviour of
transmission control protocol in wired-cum-wireless networks.
