摘要

研究了现有成簇路由算法

提出了分布式能量有效成簇路由算法

该算法主要包括3部分内容:一是选择候选簇头时通过引入平均能量因子来平衡全网节点的剩余能量情况;二是构造了基于能量和距离的能量消耗率函数以平衡节点的能量效率;三是首次提出了基于同构单跳网络的分布式能量有效非均匀成簇路由算法。理论和仿真结果均说明该算法优于EECS

生命周期比EECS延长达到约30%。

Abstract

A distributed energy-efficient unequal clustering （DEEUC） algorithm was proposed for wireless sensor net-works by research current routing algorithms. The core of DEEUC has three parts. Firstly

when tentative clusterheads are selected

an average energy factor was introduced to balance the residual energy of the whole network nodes so that it may improve the network energy efficiency. Secondly

an energy consumption ratio function was proposed to balance energy-efficient of each node. Finally

an unequal clustering algorithm was proposed for single-hop homogeneous networks. Through both theoretical analysis and numerical results

it is shown that DEEUC prolongs the network lifetime significantly against the other clustering protocols such as LEACH-C and EECS. Under general instance

DEEUC may prolong the lifetime up to 30% against EECS.
