Directional carrier sense medium access for wireless nodes
A method ( 508 ) and system ( 226 ) provide directional medium access control for wireless nodes ( 102 ) in a wireless network ( 100 ), each of the nodes ( 102 ) having a transceiver ( 228 ) and a plurality of antennas ( 232, 234, 236, 238, 240 ) in selective communication with the transceiver ( 228...

| Zusammenfassung: | A method ( 508 ) and system ( 226 ) provide directional medium access control for wireless nodes ( 102 ) in a wireless network ( 100 ), each of the nodes ( 102 ) having a transceiver ( 228 ) and a plurality of antennas ( 232, 234, 236, 238, 240 ) in selective communication with the transceiver ( 228 ). Packets ( 202 ) are transmitted from a transmitting node ( 106 ) of the nodes ( 102 ) when a channel ( 104 ) is sensed as being free in a beam direction of a selected one of the antennas ( 232, 234, 236, 238, 240 ), and in accordance with a pre-determined transmission mode ( 304 ) for the data packet ( 202 ). The transmitting node ( 106 ) is periodically placed in a forced idle state, thereby being prevented from transmitting data packets ( 202 ), but being able to receive and respond to data packets ( 202 ) from other nodes ( 102 ). |
