摘要：为了研究三维地域环境中的网络覆盖和网络寿命问题，采用十字布置策略和随机布置策略，并使用基于动态邻居节点信息的随机调度算法，研究了在这两种布置策略下的区域覆盖、点覆盖和网络寿命问题。实验结果表明，当节点数量很多时，在使用了基于动态邻居节点信息的随机调度算法之后，整个区域的区域覆盖效果变化不明显，网络寿命延长了约1.1倍。

Abstract: Aiming at studying the issues of network coverage and network of life in the threedimensional geographical environment, the cross deployment strategies and random deployment strategies were adopted, and  randomsleep dissemination algorithm based on the dynamic neighbors nodes information was used to study the regional coverage, node coverage and the network life under these two strategies. The experimental results show that, after using randomsleep dissemination algorithm based on the dynamic neighbors nodes information, the effect of the regional coverage throughout the region changes little, the network life extends about 1.1 times when there are enough nodes.
