Scripts for the experiment
Scripts used for some of the above experiments are attached below
- Wired Test with UDP (Please modify the IP address of the wired interface to point to the right subnet 10.10 is for the main grid, 10.19 is for sb9)
- Wireless Test with UDP and default auto-rate with retries (Infrastructure mode)
- Wireless Test with UDP and default auto-rate with retries (Ad-hoc mode)
