摘要
针对一种簇头节点能量高于普通节点能量的异构网络,详细分析了异构网络中普通节点和簇头节点的能量消耗特征,建立了异构无线传感器网络能量消耗模型。在此基础上,完成对簇内节点的最佳发射半径和最佳簇半径的优化计算,并给出了簇头节点的优化取值。
Energy consumption characteristics of the ordinary nodes and cluster head nodes in heterogeneous network were detailedly analyzed where the initial energy of cluster heads is higher than the ordinary nodes.Further,an energy consumption model for heterogeneous wireless sensor network was established.On this basis,the optimal transmission radius and optimal cluster radius of the cluster nodes were calculated,and the optimum values were given.
