**6.2 Ten-sensor network**

We consider a larger sensor network with 10 sensors, which cannot be dealt with by the previous decision fusion algorithm based on the Riemann sum approximation due to its heavy computation requirements. For different probabilities of channel errors, the ROC curves of the AND rule, the OR rule, the 4-out-of-10 rule, the 6-outof-10 rule, and Algorithm 2 are plotted in **Figure 4**.

Some observations in **Figure 4** are presented as follows:
