摘　　要：当前关于三维拓扑控制的研究主要侧重在保证网络的连通性,并没有很好的考虑到邻居节点度和能耗最低路径两者之间的权衡关系。针对该问题提出了一种可调节的无线传感器网络拓扑控制算法,通过调整因子r(0<r<1)动态调整网络拓扑结构,使网络具有良好邻居节点度的同时保留了部分能耗最低路径。仿真实验数据表明该算法构造的网络拓扑图具有良好的可调节性和稀疏性,同时算法在优化网络生命周期和节点功率方面都具有较明显的效果。Nowadays, the research about three-dimensional topology control has mainly focused on ensuring the connectivity of the networks, and seldom considered the balance between neighbor node degree and energy consumption minimum path. This paper proposes an adjustable topology control algorithm in three-dimensional wireless sensor networks, which can dynamically adjust the network topology control structure through changing the adjustment factor r（0 〈 r 〈 1 ） and guarantee that the network has good neighbor node degree while retaining some energy consumption minimum paths. The simulation experiment data shows that the algorithm can make the network topology with good adjustability and sparsity, and also proves that the algorithm has good effect on prolonging the net- work lifetime and the node power.
