三维无线传感器网络中的一个重要问题是传感器能量优化。为了缓解这一问题，本文引入了一种新的3D球形网络结构模型，并结合原有的能耗模型，构建了一种新的确定最优簇数和均衡总能耗的方法。由于传统的层次分簇方法产生的簇大小不同，导致网络能耗不均衡。为了缓解这个问题，我们采用了一种改进的动态层次分簇方法，并实现了两个策略，包括以下三个贡献：引入距离相似性指标，以获得更好的聚类，双簇头（CH）策略，以减少负载的簇头在一个大的集群，和节点休眠机制，以平衡网络的能量消耗。此外，我们还提出了最优簇头函数来选择每轮簇的CH，最优簇头函数是根据节点的剩余能量和位置来构造的。最后，根据网络结构确定了最优簇首函数的若干参数，以优化CH选举策略。仿真结果表明，与其他四种路由协议相比，该路由协议具有更好的鲁棒性，这对三维环境监测的应用具有重要意义。
An important issue in the three-dimensional (3D) wireless sensor networks (WSNs) is sensor energy optimization. To alleviate this issue, we introduce a new 3D spherical network structure model, and by combining the original energy consumption model to construct a new method to determine the optimal number of clusters and balance the total energy consumption. Since the different sizes of the clusters are generated by traditional hierarchical clustering, it causes unbalanced energy consumption in the network. To alleviate this problem, we adopt an improved dynamic hierarchical clustering method and implement two strategies that include the following three contributions: the introduction of the distance similarity index to get a better clustering, a double cluster head (CH) strategy to reduce the load of a cluster head in a large cluster, and a node dormancy mechanism to balance the energy consumption of the network. In addition, we also propose the optimal cluster-head function to select the CH of each cluster in each round, and the optimal cluster-head function is constructed based on the residual energy and positions of the nodes. Finally, to optimize the CH election strategy, several parameters of the optimal cluster-head function are determined according to the network structure. The simulation results show that our routing protocol is more robust compared with four other protocols, which is of great significance for the application in 3D environment monitoring.
