Then we got each degree of the sensor network nodes from
BRITE topology generator. To analyze the degree distribution,
we use Matlab to calculate datas and draw graph. As can
easily be seen from Fig. 1, the distribution of degree k
subjected approximately to Power-Law distribution. However,
the value of γ is no longer between 2 and 3, but a very large
value, which is caused by the random damage probability P e
to new generated nodes when deployed and the maxinum of
communication radius
dmax of each sensor node. It can be
easily seen that the slope of P(k) is very steep and P(k) rears
up because sensor node has a limited degree of saturation
value by 180. The existence of 0 degree nodes is result from
the random damage to new generated nodes when deployed.
