  1. 2005 Spring CS492 Lab #3 2005.10.13. Thu8:30pm-10:30pm Building E3-1, Classroom #3 Kim, Dong-Wook Lee, Dooyoung Kim, Taehee Sue Moon Dept of EECS, Div. of CS

  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. 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

  4. Lab #3: Step 1 and 2 Setting team team team team team # # # # # 2 1 9 5 6 team # 7 team # 8 team # 4 team # 3 Host AP Host AP & DHCP server 802 . 11 g network ( 54 Mbps ) access point access point ( IPv 4 _ KAIST or # channel : ( IPv 4 _ KAIST or IPv 6 _ KAIST ) IPv 6 _ KAIST ) # channel : 1 # channel : 6

  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. 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. 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

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

  10. Lab #3: Step 3 setting team # 9 team # 1 team # 7 Host AP team # 5 Host AP & DHCP server team # 8 team # 6 team # 2 team # 3 team # 4
