1. Studying TCP and UDP interactions in WiFi networks
Liu Qian Qin Shuo Gao Bo

2. TCP & UDP TCP ---connection-oriented protocol reliable and correctly
UDP---connectionless protocol
unsafe and unreliable

3. experimental procedure
Bandwidth measurement
UDP and TCP same time
UDP and TCP different time
UDP and TCP change file size and packets number
a number of UDP and TCP flow

4. TCP view
TCP file
size with
0.1mb
TCP file size with 10mb

5. TCP view
TCP file
size with 0.1mb
TCP file size with 10mb

6. UDP view
UDP file size with 0.1mb
UDP file size with 10mb

7. UDP view
UDP file size with 0.1mb
UDP file size with 10 mb

8. TCP & UDP interaction Bob computer using Inter my WiFi technique
Host 1 with ip address
Host 2 with ip address

9. TCP & UDP interaction UDP & TCP with 10s delay
TCP & UDP with 10s delay

10. TCP & UDP interaction
TCP send firstly and UDP with 1ms transaction delay.

11. TCP & UDP interaction
Change the UDP file size to 1mb with Poisson distribution

12. TCP & UDP interaction
UDP send firstly and TCP with 1ms delay.

13. TCP & UDP interaction UDP firstly and TCP,UDP with delay 1ms
UDP firstly and TCP,TCP with delay 1ms

14. TCP & UDP interaction
Change first UDP file size with 1mb

15. TCP & UDP interaction TCP firstly and TCP,UDP with delay 1ms
TCP firstly and 2UDP with delay 1ms

16. TCP & UDP interaction
change the first TCP size to 1mb and change the UDP file size to 0.1mb

17. TCP & UDP interaction
We send 3 UDP & 2TCP but with different file size and different delay.
