Considering that the scale-free topology in wireless sensor networks has poor ability of intrusion-tolerance, we use the Poisson network model with node batch arrival to construct a new scale-free topology model with intrusion-tolerance optimization. Additionally, the two adjustment factors about the residual energy and the node degree are introduced in the construction of the topology model. Then the scale-free topology whose power-law exponent can be adjusted in the range of (1, + ∞) is obtained. Finally, the power-law exponent is optimized by the network structure entropy, and its optimal value is derived. Results show that the new topology has a strong fault-tolerance. And it also can enhance the network intrusion-tolerance and has good energy-saving advantages.
