*4.3.2. Energy significant networks*

Here we discuss the case when energy is significant. The parameters are defined to be as below: α=1, β=2 and γ=1. According to proposed TOI we can get the best TOI values when data generation rate is from 0.0001 to 100.

Fig. 11 shows the result. We find from the figure that in the region of data generation rate between 0.0001 and 4.0, the non-aggregation is the best TOI. When the data generation rate is about 4-10, the figure shows that the partial aggregation is the best; the full aggregation is the best when event generation rate is larger than 10.
