IEEE802.11DCF, which is a most widely used wireless LAN employs RTS/CTS handshake as an option for mitigating effects of hidden terminals. This handshake can prevent packet collisions by exchange RTS and CTS among transmitter and receiver in order to notify length of its transmission period to neighboring terminals. However, by the handshaking, terminals overhearing RTS and/or CTS prohibit its transmission needlessly even though the terminals can transmit packet without any damaging effect for on going transmission. This paper proposes a new method for synchronous parallel transmissions with exposing terminal on the basis of overhearing RTS header information.
