Figure 2

Degree distribution of sensors network and the probability density function of its Gaussian distribution approximation for different external attacks scenario. The parameters in Gaussian distribution are estimated as (a) and , (b) and , (c) and , and (d) and .

(a) Unassailed

(b) Wormhole attack

(c) Interference attack

(d) Replay attack
