摘　　要：传感器节点的能耗问题是其关键性问题之一,现有的很多路由算法在设计之初就对能耗问题进行了专门考虑,但这些算法大多只关注节点之间的相互协调,而忽略了节点自身状态参数对降低能耗的作用。本文在分析了现有众多路由算法节能方法的基础上,以DTRDD算法为平台,为节点的能量模块加入了门限机制,以抑制低电量节点的能耗降低过快。并用GLOMOSIM进行了实验,大量仿真实验结果表明,改进后的算法对延长网络生存时间、节点死亡率等指标有明显的改善作用。one of the key issues is the energy consumed by sensor nodes,currently; many routing algorithms have taken energy consumed into special consideration at the beginning of designing. But most of them only concern the coordination among sensor nodes,while neglecting the positive function of their own status parameters in reducing energy consumed by sensor nodes,Based on the analysis of many current routing algorithms,this paper adds a door limit mechanism in energy module of DTRDD to reducing energy consumed by sensor nodes. And paper realized the improved algorithm on Glomosim platform,the result of many simulation experiments show that the improved algorithm has obviously positive effect on prolonging network life time,nodes death ratio.
