20080205429 | Channel assignments in carrier sense wireless networks - In a method for assigning transmission channels to links based on link-directionality in carrier sense wireless networks. The transmissions between two nodes of a link can be split into two channels based on their link-directionalities, one channel for transmitting traffic in one direction while the other channel for sending traffic in another direction. Simultaneous transmissions of a nearby node can be assigned based on link-directionality with a different transmission channel if it is within the carrier sensing region of the link or the same transmission channel if it is far enough from the link, which does not affect the reception of the link. | 08-28-2008 |
