Goals and Overview of Lab #3

• Goals– To introduce students to wireless ad-hod

networking– To introduce students MANET routing protocols– To measure and compare TCP/UDP performance

in ad-hoc mode

• Overview– TCP/UDP throughput measurement under Ad-hoc mode

3

Lab #3: Step 1 and 2 preparation

• Setting up your Linux laptop as an AP– Download host AP driver from web site http://

hostap.epitest.fi/

• Install iperf software on your Linux– Download iperf of linux version from our FTP

server server ftp://143.248.134.182

Lab #3: Step 1

• TCP throughput measurement• Team #1: Run host AP and iperf program on your Laptop

– server : Iperf –s

• Other team : connect to the host AP of team #1 and run iperf

– Client : iperf –c 192.168.11.x –n

• Repeat each team as host AP

• At the end, upload your log at “192.168.11.x”– server : tcp_server_[team number].txt– Client : tcp_cient_[connected server

number]_[team number].txt

Lab #3: Step 1

• UDP throughput measurement• Team #1: Run host AP and iperf program on your Laptop

– server : Iperf –s –u –p 5001

• Other team : connect to the host AP of team #1 and run iperf

– Client : iperf –c 192.168.11.x –u –p 5001 -b

Repeat each team as host AP

• At the end, upload your log at “192.168.11.x”– server : udp_server_[team number].txt– Client : udp_cient_ [connected server

number]_[team number].txt

Lab #3: Step 2

• TCP throughput measurement– Team #1: Run “iperf –c 192.168.11.x –n ”

– Team #1 and #2:

– Team #1 to #4:

– All teams:

• At the end, upload your log at “192.xxx”– tcp_[step number]_[team number].txt

8

Lab #3: Step 2

• UDP throughput measurement– Team #1: Run “iperf –c 192.168.11.x –b ”

– Team #1 and #2:

– Team #1 to #4:

– All teams:

• At the end, upload your log at “192.xxx”– udp_[step number]_[team number].txt
