Abstract

In this paper, performance analysis of the Wireless and Wired computer networks through
simulation has been attempted using OPNET as simulating tool. For wired networks, the
performance parameters like delay and throughput have been investigated with varying
transmission links and load balancers. The load-balancing has been analyzed through parameters
like analysis of traffic sent and traffic received. While in wireless networks the metrics like delay,
retransmission attempts and throughput have been estimated with varying physical characteristic
and buffer size. From the obtained results, it is gathered that performance of the wired networks is
good if high speed Ethernet links like 1000 Base X and server-load balancing policy are used
whereas the performance of Wireless LAN can be improved by fine tuning and properly choosing
the WLAN parameters. For the tested simulation scenarios the performance is observed to be better
with wireless networks using infra-red type physical characteristics and higher buffer size (1024Kb.
