In a generally positive report card on the maintenance of large parks, New Yorkers for Parks, an advocacy group, last year singled out drinking fountains as a weak link, assigning them a D grade, on average, for a range of problems.
With MR-MC architecture, multiple transmissions/receptions can happen concurrently, and neighboring links assigned to different channels can carry traffic free of interference.
Fig. 1 classifies DSs by symmetry, connectivity and number of links, assigning to each a color and a greek letter, in order to help in the discussion of the results.
For a network with multiple O D pairs, we can get the total link flows by accumulating the link flow assigned by each O D pair.
ch ← best channel in C available for link; assign ch to link in AssignedList; foreach l ∈ L do. if l is neighbor of link in ConflictGraph then.
Then starting node of the selected link is determined before a random inbound link is assigned to the nodes.
After obtaining each link flow assigned by every O D pair as well as the total link flows, we can analyze and visualize link flow sources on a selected link.

Each radio link is assigned a specific frequency band of operation, a specific transmitter radiation pattern, and a maximum transmitter power.
Figure 3 gives the total link flows assigned by the three models.
Finally, every road link is assigned a functional road classification (frc) number on the basis of its OpenStreetMap highway tag.
