20090252053 | METHOD AND APPARATUS FOR ESTIMATING LINK QUALITY - A driver for an IEEE 802.11 wireless network node determines a metric for link quality between the node and a remote node. The nodes communicate using a handshake protocol in which the first node expects to receive an acknowledgement (ACK) of receipt of a data packet from the remote node. The driver provides a measure for: collision induced losses (pc) between the first and remote nodes; a slot being erroneously detected as busy when a successful transmission could have been made (pexp) between the first and remote nodes; and a probability of successful reception of a packet when a collision occurs (pplc) between the first and remote nodes. The measure is based on a number (A) of acknowledgements received from the remote node vis-à-vis a number (T) of packets transmitted to the remote node. The driver can adjust one of carrier sensitivity or node transmission power based on the measure. | 10-08-2009 |
