2. 2 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. 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/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

4. 4 Lab #3: Step 1 and 2 Setting team#6 #7 #8 #4 #3 #9 #1 #2 #5 Host AP & DHCP server access point (IPv4_KAIST or IPv6_KAIST) #channel:1 access point (IPv4_KAIST or IPv6_KAIST) #channel:6 802.11g network (54Mbps) #channel: Host AP

5. 5 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

6. 6 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

7. 7 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. 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

9. 9 Lab #3: Step 3 preparation Install AODV Routing Protocol in your host AP
