摘要

在无线传感器网络的应用开发中,如何将传感器节点组织成一个通信网络,并将传感数据从传感器节点路由到远程接收器是一个具有挑战性的任务。以最小的功耗实现数据从源到目的的高效、可靠路由一直是研究的核心问题。因此,在无线传感器网络中,我们需要一种有效的协议来路由任何传输的数据,并延长网络的生存期。在本文中,我们提出了一种新的聚类算法——前向高效簇头(FLEECH),该算法将整个网络划分为大小递减的区域。在每个区域,我们形成多个集群。簇头(CH)的选择是基于剩余能量和每个节点到汇聚点的距离作为参数。仿真结果表明,我们提出的FLEECH模型在能耗和网络寿命延长方面优于低能量自适应聚类层次(LEACH)。

A Novel Cluster Head Selection Method for Energy Efficient Wireless Sensor Network
In the development of wireless sensor networks (WSNs) applications, organizing sensor nodes into a communication network and route the sensed data from sensor nodes to a remote sink is a challenging task. Energy efficient and reliable routing of data from the source to destination with minimal power consumption remains as a core research problem. So, in WSN we need an efficient protocol to route any transmitted data with extended lifetime of network. In this paper, we propose a novel clustering algorithm, Front-Leading Energy Efficient Cluster Heads (FLEECH), in which the whole network is partitioned into regions with diminishing sizes. In each region, we form multiple clusters. The selection of the Cluster Head (CH) is based on residual energy and distance of each node to the sink as its parameter. Simulation results show that our proposed model FLEECH outperforms Low Energy Adaptive Clustering Hierarchy (LEACH) with respect to energy consumption and extension of network life time.
