<p><P>PROBLEM TO BE SOLVED: To improve efficiency of communication between wireless communication device used for a CSMA wireless LAN system. <P>SOLUTION: The CSMA wireless communication system has one or more wireless communication devices and a communication terminal which communicates through one or more wireless communication devices. Each of the wireless communication device has a transmission buffer which stores packets and outputs the packets according to transmission timing, a means of determining a permissible delay time based upon necessary quality needed for communication, and a control means of determining the transmission timing. The control means determine the transmission timing so that a first packet for transmission is transmitted a standby time, including a period derived from a random number and the permissible delay time, after the reception of the first packet for transmission, and a following second packet is transmitted a certain fixed period after the reception of an answer packet to the first packet. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
