7. Row details
So far, we've seen that rank represents the distance of a node from the root node, and that it should increase along the DODAG (a son's rank is necessarily higher than his father's). Rank is calculated according to a given Objective Function. Rank is in fact an abstract value that has no physical unit as such, but can rather be thought of as a fixed-point number where the position of the decimal point between the integer and fractional part is determined by a value called MinHopRankIncrease.
Let's take the example of a node with a rank of 1048 and a MinHopRankIncrease value of 256 :
1048 in binary can be written as: 10000011000
256 in binary can be written as: 100000000
The decimal point position is: 100.00011000
This gives an integer part: 4
