摘要
提出了一种高效节能的链式分层无线传感器网络路由协议(ECR),阐述了协议的组织思想。本协议采用混合控制方式,有效结合中心控制方式和分布式算法的优势,产生两层链式簇结构;利用简单而高效的最大剩余能量原则选取父簇头,有效延长了网络第一个节点失效的时间和提高了网络能量利用率。通过与LEACH和PEGASIS两协议的仿真比较,论证了ECR协议的高效性。
This paper proposes a new routing protocol for wireless sensor networks called Energy-efficient Chain-cluster Routing protocol （ECR） and introduce the main idea of the protocol architecture.This protocol uses the hybrid way to manage the networks,and it takes the advantages of both central control and distributed algorithm and forms a topology with two-hierarchical chains＇ formation.ECR includes a simple but efficient cluster-head-leader selection criterion,which prolongs the time of the first node dying in the network and improves the energy efficiency.The advantage of ECR is demonstrated by the simulation of comparing with both Low-Energy Adaptive Clustering Hierarchy（LEACH） and Power-Efficient Gathering in Sensor Information System （PEGASIS）.
