The full scale of the disaster has yet to sink in.

人们还没有完全意识到这场灾难的严重程度。

The simulation results show that the mechanism extends the network lifetime effectively compared with fixed sink and random movement sink in different network scale.

仿真实验表明，相比于固定汇聚节点和随机移动汇聚节点，该机制在不同网络规模下都可以更有效地延长网络生存周期，并且节点初始能量越高性能越好。
