Abstract
An ad-hoc network wireless communication system transmits data packets from one hop to another hop in a relay manner, and includes a transmitting node for transmitting a RTS message in order to transmit the data packets, and a receiving node, existing in a next hop of the transmitting node, for transmitting a CTS message in response to the RTS message transmitted from the transmitting node. The receiving node transmits the CTS message to another receiving node successively connected to the receiving node in response to the transmitted CTS message, and the transmitting node transmits the data packets to the receiving node in the case that the CTS message transmitted by the receiving node of the next hop is received over a predetermined number of times. The ad-hoc network wireless communication system can maximize the communication efficiency in a multi-hop network with its complexity minimized by extending a MAC protocol based on a IEEE 802.11 DCF to a reservation-based MAC in the multi-hop network.
