*5.4. Number of Nodes Alive*

In Table 7, the average number of live nodes is displayed. As it can be concluded from the Table 7, the average number of live nodes was more than 30% of all node counts which confirmed the maintained network stability as it was proposed by our algorithm. Figures 10 and 11 demonstrate the number of live nodes during simulation. The results showed that HCD had better performance compared to other protocols and increased the number of live nodes during simulation. It was due to the balance between the energy consumption of different nodes as it was proposed by the presented protocol and therefore, could prevent node death.
