Research on energy saving of WSNs with cluster-based routing

在大规模传感和环境监测中,节约能源延长传感器节点生命已成为无线传感器网络最重要的研究课题之一。提供合理的能源消耗和改善无线网络生命周期的传感器网络系统,必须设计一种新的有效的节能方案和节能路由体系。方案采用一种聚类算法减少无线传感器网络的能量消耗,创建一种cluster-tree分簇路由结构的传感器网络。该方案主要目标是做一个理想的分簇分配,减少传感器节点之间的数据传输距离,降低传感器节点能源消耗,延长寿命。实验结果表明,该方案有效地降低了能源消耗从而延长无线传感器网络生命。

In wireless sensor networks （WSNs） for large scale sensor and environmental monitoring, since energy saving can prolong the life of sensor nodes, it has become one of the most important research topics. To provide reasonable energy consumption and improve the lifecycle of the sensor network system in WSNs, a new effective energy saving scheme and energy saving routing system is desirable. We design a clustering algorithm to reduce the energy consumption of WSNs and create a WSN routing structure based on cluster-tree using the sensor node cluster technology. The main goal of our scheme is to make an ideal cluster distribution, reduce the data transmission distance between the sensor nodes, decrease sensor nodes and the energy consumption, and prolong the lifecycle of WSNs. Experimental results show that this scheme can reduce network energy consumption and prolong the lifecycle of WSNs.
