能量资源的有效管理是无线传感器网络（WSNs）中一个具有挑战性的研究领域。最近的研究表明，分簇是一种有效的拓扑控制方法，将网络组织成一个连接的层次结构，平衡传感器节点的流量负载，提高整体的可扩展性和生命周期的无线传感器网络。受聚类技术优势的启发，本文有三个主要贡献。首先，我们提出了一种能量有效的集群形成算法称为主动节点集群形成（ANCF）。提出ANCF算法的核心目的是通过在网络中提供不等大小的簇，使大数据流量和高能耗负载在网络中均匀分布。所开发的计划任命每个簇头（CH）附近的汇和传感事件，而其余的一组簇头（CH）被任命在每个集群的中间，以实现最高水平的能源效率在密集部署。其次，我们提出了一个轻量级的感知机制，称为主动节点感知算法（ANSA）。提出ANSA算法的主要目的是通过在每个簇中指定一组在事件附近具有满意覆盖的主动节点来避免高感知重叠数据冗余。第三，我们提出了一个主动节点路由算法（ANRA），以解决复杂的簇间和簇内的路由问题，在高密度部署的基础上的节点支配值。通过网络模拟器NCTUNs 6.0进行了广泛的实验研究表明，我们提出的方案优于现有的路由技术在能源效率，端到端的延迟和数据冗余，拥塞管理和设置鲁棒性。(C)2015爱思唯尔有限公司版权所有。
Efficient management of energy resources is a challenging research area in Wireless Sensor Networks (WSNs). Recent studies have revealed that clustering is an efficient topology control approach for organizing a network into a connected hierarchy which balances the traffic load of the sensor nodes and improves the overall scalability and the lifetime of WSNs. Inspired by the advantages of clustering techniques, we have three main contributions in this paper. First, we propose an energy efficient cluster formation algorithm called Active Node Cluster Formation (ANCF). The core aim to propose ANCF algorithm is to distribute heavy data traffic and high energy consumption load evenly in the network by offering unequal size of clusters in the network. The developed scheme appoints each cluster head (CH) near to the sink and sensing event while the remaining set of the cluster heads (CHs) are appointed in the middle of each cluster to achieve the highest level of energy efficiency in dense deployment. Second, we propose a lightweight sensing mechanism called Active Node Sensing Algorithm (ANSA). The key aim to propose the ANSA algorithm is to avoid high sensing overlapping data redundancy by appointing a set of active nodes in each cluster with satisfy coverage near to the event. Third, we propose an Active Node Routing Algorithm (ANRA) to address complex inter and intra cluster routing issues in highly dense deployment based on the node dominating values. Extensive experimental studies conducted through network simulator NCTUNs 6.0 reveal that our proposed scheme outperforms existing routing techniques in terms of energy efficiency, end-to-end delay and data redundancy, congestion management and setup robustness.
