基于DBL模型的网络节能研究

Research of the Network Energy Saving Based on DBL Model

摘要: 在无线传感网络中，多跳的分簇路由协议大多采用固定层边界的模型。层边界固定的模型使得节点的备选簇头数量受限，这样就会制约网络的生存时间。针对PMRC（Progress Multi-hop Rotational Clustered）固定层边界模型对网络寿命的限制，提出一种DBL（Dynamic boundary layer）模型，即层边界动态变化的模型，该模型可动态的改变相邻层的边界结构，来平衡同一层簇头的能量消耗。通过仿真实验表明此方法能够很好的实现能量的有效利用，使网络生存时间得以延长。

Abstract: In wireless sensor networks,many jump clustering routing protocol is used mostly fixed boundary layer model.Layer boundary fixed model makes the node of the cluster head optional quantity is limited,so will restrict the network life time.This paper PMRC (Progress Multi-hop Rotational Clustered) fixed layer boundary model for network life limit,this paper puts forward a DBL (Dynamic boundary layer) model,that is,the Dynamic changes of boundary layer model,this model can be used to Dynamic change of adjacent layer boundary structure,to balance the same layer cluster head of energy consumption.Through the simulation results show that this method can well realize the effective use of energy,and make the network survival time prolonged.
