... handshake, the delay is higher than the enabled handshake. The reason is that when the handshake is enabled, the attack causes to drop mostly the RTS and CTS frames which lead to their retransmission. In ... consists of two areas as authorized and attacker. The authorized area consists of two wireless stations associated to the access point which follow the I...
