From the analysis , safely come to the conclusion : when the monitor area is extending , high aggregation rate can effectively save the network energy ; with the strength of the aggregation increasing , energy consumption of each node tends to equilibrium 分析表明,當監測區域擴大時,強融合率將有效節省網絡能耗;隨著融合強度的增加,網絡中節點能量消耗趨于平均。
