We can also observe from the two figures that EEPCA, MCR, and EDFCM have better performance than the two former protocols, SEP and LEACH.
We can also discover that EEPCA, MCR, and EDFCM have better performance in stable period than LEACH and SEP, because they can make the nodes dissipate their energy uniformly and balance the energy consumption to provide longer stable period.
We can also observe from Figure 7 that EEPCA has better network monitoring quality than the other algorithms.
And, for the same reason we discussed above, EEPCA has the best network monitoring quality in these protocols, and the result shows that MCR is better than EDFCM.
Because EEPCA has a good ability of balancing energy consumption, it can achieve a longer stable period and lifetime no matter whether the network is homogeneous or heterogeneous.
