! 2.1 Link Quality
! --------------------------------------------------------------------
! 
! The link quality between a directed node pair (A,B) is the probability
! that a packet transmitted by A will be successfully received by B. The
! bidirectional link quality of an undirected node pair (A,B) is the 
! product of the link quality of (A,B) and (B,A). This definition
! assumes independent link losses. It also includes the case when
! the link quality of (A,B) and (B,A) are different; this can occur
! due to local interference or noise.

  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.
