%X <p>In view of cascading failure problem of scale-free fault tolerant topology in wireless sensor networks, the scale of cascading failure caused from one random fault node is deduced based on the probability generating function. The critical load value of the cascading failure is discovered under the condition of power function load distribution. The research result shows that a random fault node will cause cascading failure of the entire network when the load parameter exceeds its critical value. Simulations verify the correctness of the analytical derivation.</p>
