-The link quality between a directed node pair (A,B) is the probability

 --------------------------------------------------------------------
 
 In a node pair (A,B), with B as the node of reference, in-bound link
 quality is a value in the range of 0 to 255 that describes the quality
 of the link from A to B estimated by B by counting the successfully
-received packets from A among all the transmitted packets or using
-link quality indicators such as LQI and RSSI provided by the radio on
-the node B, or some other methods.
