Abstract

Exposed terminals play a crucial role in the throughput of a wireless ad-hoc network. The 802.11 MAC protocol introduces no methods for decreasing the amount of the terminals exposed to the transmission of the CTS message by the receiver. This paper proposes a new MAC protocol, which by using power capturing mechanisms, decreases the amount of such terminals. This allows for the better utilization of the available bandwidth via increasing the chances for parallel transmissions in situations where the MAC protocol of the 802.11 standard would allow for only one transmission to occur at a time.
