Abstract
A collision of data transmitted in an ad hoc network in which a communication system such as a wireless LAN system is managed without a master control station is minimized. A communication station in the network estimates a time at which a neighboring station will transmit a signal and, when a communication start request is received from some other communication station, adds time information, generated based on the length of time to the estimated time, to a response to the communication start request. This allows the reception side communication station, which knows in advance that the transmission will be occupied by a transmission from other communication stations, to cause the transmission side communication station to transmit data at a time other than that occupation time.
