Wireless LAN - 802.11

How are packet collisions modeled in NetSim?
Packet Collision is a theoretical concept. In the real world a packet is not a "physical" entity that can collide. Therefore a "collision&quo...

How do I configure 802.11 simulation for RTS / CTS to work ?
The RTS / CTS mechanism is invoked when the packet size crosses the RTS threshold. And in general you would wish to use RTS / CTS only when transmitting dat...
