Wireless communication system, wireless communication apparatus, wireless communication method, and computer program
First Claim
1. A wireless communication system in which communication apparatuses perform band reservation to reserve a communication band for use, a plurality of reservation types each defining a different priority for a band reservation, and to handle a conflict of band reservation use between two or more communication apparatuses, the wireless communication system comprising:
- means for comparing reservation type defining priority of each of the communication apparatuses having a conflicting band reservation;
means for continuing band reservation use of a first communication apparatus having a reservation type of a higher priority than a second communication apparatus having a reservation type of a lower priority; and
means for moving band reservation use of the second communication apparatus having the reservation type of the lower priority to another area.

Abstract
In the case where there is a conflict over a band between communication stations that have reserved the band, the communication stations mediate and avoid the conflict of reservation use with low-load processing. In a wireless communication system, band reservation use is permitted, and a plurality of reservation types are provided according to priority of communication. A communication station that performs reservation use describes a reservation type and a rock-paper-scissors value in a beacon. When there occurs a conflict of reservation use at some area, reservation use having higher priority remains, and a communication station that has performed reservation use having a lower priority moves it to another area. In the case where there is a conflict between reservations having the same priority, the communication apparatuses that have performed reservation use perform control by rock-paper-scissors between themselves, and move the reservation of the apparatus that has lost by the judgment.
